Fig. 1.1 shows the SR–HSP series system robot.

Structure

1.1.1

The robot consists of the basic robot, controller and teach pendant connected with the controller,

which is intended for teaching positions and entering programs.

To make the robot do a job, programs and position data are necessary so that the robot can

execute the job.

Normally, such programs and position data should be created and stored in the controller memory

beforehand. When operating the robot, the controller interprets the contents of programs and

gives the robot the instructions on motions according to the program sequence to cause the robot to

do the job.

Programs and position data for one process which are put together are called the task program,

which can also be called the file when they are loaded to and saved in the controller.

As the control unit of the controller uses the SCOL language (symbolic code language for robot), a

task program can be easily created and entered as if you were creating a BASIC program.

Entry of position data is possible in the three manners; guiding by the robot and teach pendant,

entry of coordinates through the teach pendant and manual guiding of the robot by the operator

after turning off the servo control.

The teach pendant can be shared by many robots, and automatic operation is possible even when it

is disconnected from the controller.

Also, saving and management of files are very easy, using an optional FDD unit.

In addition to the above, a great number of options and functions including optical sensors for

position data compensation and interface software with a personal computer are also available.

Fig. 1.2 shows a system configuration of SR series Toshiba system robots.

System Configuration of SR Series System Robot

1.1.2

Functions

(1) Control method

A 32-bit microprocessor serves as the central processor.

A 16-bit microprocessor is used for communication control and a 32-bit microprocessor for

each axis servo control, thus servo control, robot language processing and editing are

possible. Also, an 8-bit microprocessor is employed for the teach pendant to realize a more

intelligent robot.

(2) Motion

The motion comes in three types; PTP (point-to-point) control, CP (continuous path) control

(linear interpolation, circular interpolation (option)) and short-cut.

PTP control: Dedicated SCOL language MOVE

This control is used to move each axis fast to a specified position, irrespective of a path.

Simultaneous operation is executed in which all axes start moving simultaneously and

finish simultaneously.

CP control (linear interpolation): Dedicated SCOL language MOVES

This is the path control in which all paths are predetermined. Each axis moves between

two taught points in the Cartesian coordinate system along the shortest distance. It is

used to move the end effector of the robot along a straight line.

CP control (circular interpolation): Dedicated SCOL language MOVEC

Each axis moves on an arc from the current point to the target point via specified mid-

point.

Short-cut

Each axis passes the vicinity of a taught point without reaching and stopping at the same

point, then moves to the next point. The travel time can be reduced.

(3) Number of controlled axes

A maximum of five axes can be controlled simultaneously. Additionally, the air cylinder can

be driven.

(4) Storage capacity

The storage capacity of the RAM drive is 512 K bytes.

To save files, a 1.44 M bytes FDD unit (option) is available.

The rate of file active area is displayed in units of byte on the teach pendant.

Storage capacity of program alone (approximation): 500 points for 1,000 lines

A floppy disk is initialized in the MS-DOS format. It should be noted that reading of the data

contained in floppy disks for the SR-5500 controller is not possible.

(5) Storing method

A file (programs and position data) is stored in the memory backed up by a battery. Check is

performed on battery voltage drop and destruction of memory contents, and if an abnormality

has generated, an alarm is output to inform the operator to that effect.

(6) Number of program files

Up to 256 program files can be registered.

(7) Position detection

Detected by an absolute encoder on the no-load side of the AC servo motor.

(8) External input/output signals

Standard external input

In all, 32 inputs insulated optically are open to the user. Branch of a program and

interlock by input signals can be programmed easily, using the robot language.

STE 58760

Standard external output

In all, 24 outputs of transistor and open collector are open to the user. Output signal

ON/OFF and pulse output can be programmed easily, using the robot language.

Extension external input/output

When an option board is added, addition of 24 inputs and 16 outputs is possible.

Furthermore, sixty-four each of input and output that can operate as the slave station of

our TC200 programmer are available.

(9) External operation signal

To facilitate construction of an FA system, servo ON, servo OFF, start, feed hold, cycle stop,

robot operating speed, program reset, etc. are possible by external signals in the external-

automatic mode.

In any other mode, these external signals are neglected, except for the servo OFF signal.

The low speed instruction becomes effective also in the internal-automatic mode, however.

Also, the signals of ready, automatic operation ON, external-automatic mode ON, fault, servo

ON, emergency stop ON, etc. necessary for external operations are output.

(10)

Teaching method

A program can be entered easily through the teach pendant, using the robot language

(SCOL). Position data can be given in the following three manners.

Teaching by remote-guidance through teach pendant.

Entry of coordinates through teach pendant.

Manual guidance in servo-free status.

(11)

(12)

File editing function

A file can be registered and deleted on the teach pendant. Program editing is also

possible on the display. When the FDD unit (option) is provided, reading and writing of

data contained in a floppy disk of 1.44 MB MS-DOS format are possible. Thus, a program

can be edited on the personal computer.

Speed setting

Program

Robot travel speed can be programmed in the range of 1 to 100 % in 1 % increments.

Override

A programmed speed can be overridden in the range of 1 to 100 % in 1 % increments.

STE 58760

Acceleration/deceleration speed setting

Speed at acceleration can be programmed in the range of 1 to 100 % in 1 % increments,

using the ACCEL instruction.

Likewise, deceleration speed can be programmed in the range of 1 to 100 % in 1 %

increments by means of the DECEL instruction.

Speed limit

A limit can be set on the maximum speed so that the robot speed can always be slower

than this limit. It is convenient to use in the TEST RUN mode.

(13)

(14)

Servo gain ON/OFF function (servo-free)

Servo control ON and OFF are possible for each axis, using the program instruction (GAIN).

The same operation is also possible through the teach pendant.

Torque limiting function

A limit value for each joint motor torque can be set in the range of 0 to 300 %, using the

program instruction.

When transferring or inserting a workpiece, there are occasions in which the robot motion is

mechanically obstructed due to faulty workpiece, etc., or no excessive force should be

exerted on the workpiece. When this happens, it is possible to prevent damage of the

work hand or robot by limiting the motor torque.

(15)

(16)

(17)

Interruptive function

When any external signal is input during robot motion, the motion can be stopped instantly

and required processing can be executed by means of external input signals.

Coordinate system setting function

Coordinate systems of the robot and peripheral equipment can be established through the

teach pendant.

Program function

When the robot language SCOL is used, jump, subroutine, loop, interruptive processing,

delay time, speed setting, interpolation, hand operation, vertical movement and rotation of

each axis by an air cylinder are possible.

For details, see the Robot Language Manual.

(18)

Operation

In the internal-automatic operation mode, the five modes are available; step, motion step,

cycle, continue and machine lock. (The step and machine lock modes can be selected

only in the test operation.)

In the external-automatic operation mode, the continue or cycle mode can be selected.

STE 58760

Step

A program is executed step by step.

Motion step

A motion instruction given in a program is executed once.

Cycle

A program is executed until the END instruction of main task has been executed. That is,

a series of operation is executed only once.

Continue

A program is executed, neglecting motion instructions in the same man-machine lock

program (i.e., the robot will not move).

Machine lock

A program is executed, neglecting motion instructions programmed, as if the robot were

actually moving.

(19)

(20)

Working range limitation

To detect the stroke end limit, soft limits are provided, which can be set by the user at his

discretion.

Self-diagnosis function

The system performs check on the servo fault, overtravel, transmission error, battery

voltage drop, control power fault, parameter destruction, etc. If an error is detected, an

appropriate error number is displayed on the teach pendant, and the servo power is turned

off according to the error.

(21)

(22)

FDD unit (option)

Files stored in the controller memory (programs and position data) can be stored in floppy

disks. It is also possible to load the data of the floppy disks into the controller. A floppy

disk is initialized in the MS-DOS format. It should be noted that reading of the data

contained in floppy disks for the SR-5500 controller is not possible.

Personal computer and printer interface

The interface function of an personal computer and printer is standard-equipped. Thus,

management of the robot language and line management can be performed very easily,

using the personal computer. Additionally, management of a group of robots is possible by

the host computer, thus construction of a highly advanced FA system can be realized.

1.2 OUTLINE OF OPERATIONAL PROCEDURE

At the least, the following operations are required to start up the robot.

(1) Installing the robot and controller at the site and connect the cables in place.

Unpack the controller and robot and install them at the site. After the installation work is

complete, connect cables between the controller, robot and peripheral equipment. For details,

see the Transportation and Installation Manual.

(2) Starting up and manually guiding the robot.

After robot installation work is complete, turn on the robot power so that it can be manually

operated. The operation range of the robot should have been set before teaching the

operation. For the setting procedure, see Chapter 2, "Power ON to Manual Guidance".

(3) Teaching the contents of the operation to the robot.

To make the robot work, a robot language program and position data should be prepared.

After the robot has been started up, input the program and position data. An example of the

operation is described in Chapter 4, "Example of Simple Operation". For details, see the

Operating Manual and the Robot Language Manual.

(4) Checking the operation being taught with a test run.

Check that the robot correctly works as taught. An example of the operation is described in

Chapter 4, "Example of Simple Operation". For details, see the Operating Manual.

(5) Making the robot work in an automatic operation mode.

After checking that the robot correctly works as has been taught, make the robot work. An

example of the operation is described in Chapter 4, "Example of Simple Operation". For

Check that cables have been securely connected between the robot body and controller and

between the controller and teach pendant.

Note 1)

In the automatic operation mode, it is not necessary to connect the teach pendant to the robot

body. Even if the teach pendant is not to be used, it is necessary to connect a dummy

connector to the teach pendant connector on the controller. Otherwise, the servo power

cannot be turned on.

Note 2)

The low speed instruction signal, servo OFF signal, and emergency stop signal of the external

control signal cables should be short-circuited even if they are not used. For the connector

locations and terminal numbers to be short-circuited, see the Transportation and Installation

Manual. (For the connectors attached to the controller, such signal cables have already been

short-circuited.)

1.4 COORDINATE SYSTEM

A coordinate system comes in a world coordinate system, base coordinate system and tool

coordinate system. Once the coordinate system is established, positions where the robot has to

move can be set by coordinate values.

A function which offsets the coordinate system is also provided, and even if the robot position or tool

has been changed, the entire program need not be modified accordingly.

In addition to the above, a work coordinate system is also available, which is useful to create

position data for palletizing operation.

Positional relationship of respective coordinate systems is shown in Fig. 1.3.

World coordinate system

A coordinate system the user defines in a space at arranging equipment or workpieces is

called the "world coordinate system."

Base coordinate system

A Cartesian coordinate system based on the robot center is called the "base coordinate

system." Normally, each axis is set based on the origin (0°) orientation.

The base coordinate system can be offset by entering a deviation of each axis of the world

coordinate system. Thus, each time the coordinate system is changed, operation points

need not be taught to the robot.

(3)

(4)

Tool coordinate system

A Cartesian coordinate system based on the tool set surface (i.e., flange surface) of the

robot end effector is called the "tool coordinate system."

Like the base coordinate system, the tool coordinate system can also be offset so that the

robot can move on the basis of the tool edge. Thus, the operator can teach the robot

based on the tool edge.

Work coordinate system

A coordinate system defined in an actual working space, such as workpiece layout and

pallet, is called the "work coordinate system. Thus, data can be created easily at

palletizing or offline teaching.

1.5 SYSTEM CONFIGURATION

Basically, the robot system is composed of the basic robot, basic controller and teach pendant.

The controller has comprehensive interface functions to allow construction of various systems.

Fig. 1.4 shows the maximum system configuration.

The basic controller consists of the control panel, CPU printed board serving as the control center,

relay printed boards relaying external output signals and other units (such as servo driver).

An external control unit required for external-automatic operation is not provided, which

should be prepared by the user at job site.

A system disk (used for cold-starting the system) is attached to the controller. Keep it in your

custody.

(3) Internally controlled automatic operation

Operation of the robot according to files (programs and position data) loaded to the controller

is called the "automatic operation." The automatic operation can be controlled internally and

externally.

Start and stop of the robot through the control panel of the controller is called the "internally

controlled automatic operation."

Note:

Automatic operation is possible by connecting or disconnecting the teach pendant to

or from the controller.

When the teach pendant is disconnected, connect a dummy plug to the teach

pendant connector. Unless the dummy plug is connected, the servo power cannot

be turned on.

(4) Externally controlled automatic operation

Automatic start and stop of the robot with external signals is called the "externally controlled

automatic operation."

(5) Floppy disk

Files (programs and position data) stored in the controller can be saved in floppy disks (3.5

inch), using an optional FDD unit. It is also possible to load the data in the floppy disks into

the controller.

(6) Automatic operation, using optical sensors (option)

Automatic operation is possible by using an optical sensor system while recognizing the items

subject to the operation and compensating position data.

2.1 TURNING ON MAIN POWER

After checking that there are no problems with the controller and robot cable connections, turn on

the main power to start up the robot. There are two methods to turn on the main power; cold

starting and hot starting. Normally, only the hot starting is required. For details, see Para. 2.1.2.

2.1.1 Cold Starting

After cold starting has been conducted, programs and data necessary for operating the robot

are loaded from the floppy disk to the controller. Once the cold starting has been effected, it

need not be repeated unless the robot went wrong. If there is some problem with the robot,

perform hot starting.

Caution

If an abnormality has generated or the POWER LED lamp on the control panel remains off after the main

power switch of the controller was turned on, turn off the main power immediately and confirm the wiring.

Otherwise, you will be struck by an electric shock or a fire will break out.

Caution

When the cold start operation is conducted, the contents of the controller memory (including a robot

language program, position data, and user parameters) are initialized. To prevent user data from being

erased, be careful not to unintentionally conduct the cold start operation.

Be sure to back up the user programs. It is also recommended to always back up all user programs.

Conduct the cold start operation in the following manner.

(1) Insert the system disk into the FDD unit (option). (For the connections, see the Interface

Manual.)

(2) Hold the floppy disk in the manner that the label side is up and the disk shutter (metal

cover) enters the FDD first. Lightly insert the attached floppy disk (system disk) into the

FDD unit until a click is heard.

STE 58760

Note)

The disk provides a write-protection tab which prevents the user from mistakenly erasing the

contents. When using the system disk, prior to inserting it into the FDD, make sure to slide the

write-protection tab outward. When the tab is in the outward position (figure (a)), data cannot

be written on the floppy disk. On the other hand, when the tab is in the inward position (figure

(b)), data can be written on the floppy disk. In any case, slide the tab all the way until a click

sound is heard.

(3) Turn on the MAIN POWER switch on the control panel.

Turn on the MAIN POWER switch on the control panel. When the main power is turned on,

the POWER LED will light up.

Note)

Should the "POWER LED" not light even if the MAIN POWER switch is turned on, or should

any fault occur, immediately turn off the MAIN POWER switch and check the cables connected

to the controller.

The LED on the FDD blinks several times and the contents of the floppy disk are read to the

controller. When the controller is correctly started up, the following message appears on the

LCD screen on the teach pendant.

■

EDIT LOAD SAVE TESTRUN> RESET NEXT

When the cold start operation is conducted, the controller works as follows.

When the power is turned on, the controller reads in the system programs from the system disk.

While the system programs are read, the lamp on the "START" switch blinks. When the system

programs have been read in from the disk, the lamps on the "START", "STOP" and "CYCLE

STOP" switches light up for 0.5 sec. After that, the lamp on the "STOP" switch lights up and

the screen as shown above appears. After that, files of parameters and so forth are read to

the controller. After all the required files are read to the controller, the contents in the

automatic execution file are executed. In this state, the controller can be operated.

For details of the automatic execution file, see 3.5, "Batch Process".

When an error occurs during the cold start operation, take proper action corresponding to the

error message appearing on the screen.

(5) After the controller has been started up, remove the system disk from the FDD. When

pressing the FDD pushbutton, the floppy disk is slightly ejected from the disk entrance.

Hold the label portion of the disk and remove the disk.

Note)

While the LED on the FDD lights or blinks, be certain not to remove the floppy disk from the

entrance. Otherwise, the FDD, floppy disk, and/or controller may be damaged.

The cold start operation is now complete.

2.1.2 Hot Starting

While programs and data necessary to operate the controller are stored in memory of the

controller, the controller can be started up directly without performing the cold start operation,

which is called the “hot start”. Once the cold start operation has been conducted, unless any

fault occurs in the robot system, it is not necessary to conduct the cold start operation again.

Caution

If an abnormality has generated or the POWER LED lamp on the control panel remains off after the main

power switch of the controller was turned on, turn off the main power immediately and confirm the wiring.

Otherwise, you will be struck by an electric shock or a fire will break out.

When hot starting has been done, the controller enters a program reset status.

Conduct the hot start operation in the following manner.

(1) Turn on the MAIN POWER switch on the control panel.

Turn on the MAIN POWER switch on the control panel. When the MAIN POWER is turned on,

turned on, or should any fault occur in the system, immediately turn off the Main Power switch

and check the cables connected to the controller.

Note 2)

If the system disk was in the FDD unit when the main power was turned on, the controller will

perform cold start. Before turning on the main power, check to see that the system disk has not

been inserted into the FDD unit.

Note 3)

If a floppy disk which contains any of the files CONSTRUC. SYS, SYSTEM. PAR, USER. PAR,

EXTRNSEL. SYS, SCOL. LIB, ALARM.MES, or AUTOSTR. BAT has been inserted into the

FDD unit, the contents of the files will be read to the controller when the main power is turned

on. For an outline of each file, see Chapter 5.

STE 58760

During hot start-up, the controller works as follows: When the main power is turned on, the

controller reads in the contents of the floppy disk in the FDD. Unless the system disk has not

been inserted, the system stored in the controller conducts hot starting. During the hot start

operation, the lamp on the "START" switch on the control panel blinks. When the controller is

started up, all the lamps on the "START", "STOP" and "CYCLE STOP" switches light for approx.

0.5 sec. After that, the lamp on the "STOP" switch lights and the screen as shown above

appears. After that, files for parameters and so forth are read in from the floppy disk to the

controller. Any required files are read to the controller.

After all the files have been read, the automatic execution file is executed. In this state, the

controller can be operated.

For details of the automatic execution file, see 3.5, "Batch Processing".

If an error occurs during the hot start operation, take proper action corresponding to the error

message which appears on the display. If the controller cannot be started up using the hot

start operation, conduct the cold start.

The hot start operation is now complete.

2.2 SETTING CONTROLLER ENVIRONMENTAL CONDITIONS

Before operating the robot system, it is necessary to set data for the controller. This data is stored

in the system configuration file (file name: CONSTRUC. SYS).

In addition, the controller requires the operator to set date and time.

This data setting is referred to as setting the environmental conditions of the controller. Details of

how to set individual data items are described in Chapter 3, "Setting Environmental Conditions for

the SR7000 Controller". This paragraph outlines setting environmental conditions for the controller.

Controller environmental conditions should be set only when the robot is installed. The included

system disk stores standard environmental condition values corresponding to the robot being

delivered. If the operator does not need to change the preset values, he or she can use them as

they are. (Date and time have been set at the factory.)

Set the environmental condition values of the controller in the following manner.

(1) Set the current date and time.

(2) Check the contents of the system configuration file.

(3) When selecting files to be executed with external input signals, create an external selection

file.

(4) When changing the contents of the system configuration file or when creating the external

selection file, the contents should be saved on a floppy disk.

(5) Turn off the power supply of the controller and then start up the controller using the hot

start operation.

For details of how to set environmental condition values of the controller, see Chapter 3,

2.5 MANUAL GUIDANCE OPERATION

The manual guidance operation can move the robot along various coordinate systems as well as

moving each joint (axis). The operation which guides each joint of the robot is named JOINT

guidance, while the operation which guides the robot along a coordinate system is named

coordinate guidance. The operator can select either the world, work, or tool coordinate system in

which to move the robot. The coordinate system in which the robot moves depends on the robot

type. For details of the robot's coordinate system, see the Introductory Manual.

When operating the robot, take care that the robot does not hit workers or anything else. Because

manual guidance is conducted in the manual mode, it is necessary to place the MASTER MODE

KEY switch on the control panel in the "MANU" (manual mode) position.

Conduct manual guidance for the robot in the following manner.

2.6 MOTION RANGE LIMIT

In executing the automatic operation or in teaching a position, the operation range and the teaching

range of the robot can be limited. When they are limited, the robot is not moved to a position out of

the operation range in the automatic operation, so that the position out of the operation range

cannot be taught. The limitation of the operation range is called the joint limit. The joint limit

should be set in two directions of + direction and - direction of each joint.

The joint limit can be set in the following two methods. 1st method: Guide the robot and teach

positions. 2nd method: Input the position of each joint with numeric values from the teach

pendant.

When a joint limit is changed, software which used to work may not work anymore. Thus, any joint

limit should not be unintentionally changed.

Each joint limit has been set to the maximum motion range at the factory. Unless there is

necessity to change a joint limit, use it as it has been set at the factory.

Note)

The joint limit values are stored in the user parameter file (USER. PAR). Before the operator

changes the joint limit values, it is recommended to back up the user parameter file. For an

instruction of how to back up the file, see 5.5, "Backing Up Files".

2.6.1 Setting Joint Limit Values by Teaching

The joint limit values are taught in the following manner.

(1) Check that controller monitor command menu appears at the bottom of the LCD display on

the teach pendant.

CHAPTER 3

SETTING ENVIRONMENTAL CONDITIONS

FOR THE SR7000 CONTROLLER

The operator should set items such as the robot configuration and the communication channel

modes before he or she operates the robot system. The operator should set the date and time for

the controller for file management and fault display information. The operation for setting such

data is called controller environmental condition setting. Except for the date and time, such data is

stored in a system configuration file (CONSTRUC. SYS).

In addition, to use external signals to select a file to be executed, it is necessary to first create an

external selection file (EXTRNSEL. SYS).

This chapter describes how to set individual data which defines the environmental conditions of the

controller.

3.1 SETTING DATE AND TIME

The controller provides a clock function which indicates the current date and time. When the robot

system detects an error, the function indicates the date and time when the error occurred along with

a related error message.

Date and time have been set at factory. However, when the controller power has been turned off

for a long time, the controller clock may become off. In this case, it is necessary to reset the

correct date and time.

Note)

The accuracy of the controller clock is within 15 sec per month. Thus, it is necessary to

periodically check and adjust the clock.

3.1.1 Setting Date

Set the current date in the following manner.

(1) Turn on the controller main power and place the MASTER MODE KEY switch on the

control panel in the "MANU" position. The following monitor command menu will appear

at the bottom on the teach pendant LCD display.

... [= "SR-L"]

(1) Robot axis configuration

Specifies which of the jointed axes 1 to 4 are to be used. The setting is to be changed when the

number of axes of the robot is less than four, or when a servo motor is to be used outside of the

robot. The data are to be specified for 4 axes separated with a space. To use an axis, set

that axis to "1". To not use an axis, set that axis to "0".

Example)

When the Z axis is not used for a horizontally articulated type robot, set the data to [= 1 1 0 1].

Note 1)

Robot axes vary by robot type. For details of the robot axes, see the Transportation and

Installation Manual.

Note 2)

This data should be set for all four axes.

(2) Type of joint

Specifies whether the joint type of the robot is a directly moving joint or rotating joint. The data

are to be specified for 5 axes separated with a space. To use the linear moving axis, set that

axis to "0." To use the rotating joint, set the axis to "1."

3.4 SETTING EXTERNAL SELECTION FILES

To select a file to be executed using external input signals, the name of the file should have first

been registered in the external selection file (EXTRNSEL. SYS). This paragraph describes the

contents of the external selection file. For details of how to create and change this file, see 3.2,

"Changing File Data".

Note)

To select a file to be executed from outside of the controller, it is necessary to specify an input

signal line to be used for selecting the file as well as creating the external selection file. For

details of the system configuration file, see 3.3, "Setting System Configuration".

3.4.1 Signals Used for Selecting File

To select a file, use a signal having up to 8 consecutive signal points among 32 input signal

points. Signals used to select a file are specified in the system configuration file. Change

the data line corresponding to the file selection signal line in the system configuration file in

accordance with the signals to be used.

Example)

When using the 6 points (extending from points 10 to 15) of an input signal, change the data

line of the system configuration file as follows.

[9.]SPECIFY FOR EXTERNAL FILE SELECTION SIGNAL

[1<=CH.NO. <=24,1<=LENGTH<=8]

= 10 6

To actually select a file, take the timing using a strobe signal and acknowledge signal. For

details of the signal timing for selecting a file, see the Interface Manual.

Any signal used for selecting a file is read in as a file selection number. The file selection

number is one digit numeric value in binary notation representing the conversion of the state of

each input signal being specified. The smallest input signal number of the input signals being

specified is treated as bit 0, and, in order, each bit corresponds with its input signal number.

The ON and OFF states of each signal correspond with 1 and 0, respectively.

3.4.2 Contents of File

The names of files written in robot language are registered on one line at a time in the external

selection file. Each file name corresponds with the file selection number, which is determined

by subtracting a 1 from the number on which the file is registered. The file on line 1 accords

with the file selection number 0; the file on line 2 accords with the file selection number 1; and

so on. The number of characters per line should be 12 characters. For an example of how to

create a robot language program file, see Chapter 4, "Example of Simple Operation

For a detailed description, see the Operating Manual. For details on robot language, see the

Robot Language Manual.

The following are examples of external selection files.

STE 58760

In the above example, when the file selection number is 0, the file MAIN0. SRC is selected;

when it is 1, the file MAIN1. SRC is selected; and so on.

Note 1)

Files registered in the external selection file must be in the memory of the controller. Any file

which is not in the controller memory cannot be selected.

Note 2)

When a file to be executed is selected externally, the file corresponding to the line of the

external selection file is selected. Thus, be careful with the order of file names in the external

selection file.

Note 3)

When registering file names in the external selection file, do not place a blank line between any

file names.

Note 4)

If the file name to be registered consists of less than 12 characters, include a space or spaces

before the file name to make the total number of characters 12. DO NOT enter a space or

character at the 13th character and after.

3.5 BATCH PROCESSING

The SR7000 controller provides a function which sequentially executes a set of commands entered

from the teach pendant. This function is named a batch processing. To conduct a batch

processing, it is necessary to describe commands in the order of execution in a file. This type of

file is named a batch file. When a batch file name is used like a command, commands listed in

that batch file are executed in sequence.

3.5.1 Batch File

A file where commands are to be executed in a batch is called a batch file. The extension for

all batch files should be ".BAT".

The following table lists commands available for batch processing. For details of how to use

each command, see the Operating Manual.

STE 58760

Note 1)

"AUTO" in the "Available mode" column represents the internal automatic mode, the external

automatic mode, and the test operation mode. "MANU" represents the manual mode (all

modes beside the automatic modes listed above).

Note 2)

When any command which is not effective in the current mode is used, an error occurs and the

command will not be executed. In this case, any command where an error occurs is skipped

and the remaining commands are executed in sequence.

Note 3)

When a batch processing is specified in another batch processing, the former batch processing

is complete when the last command of the latter batch processing being called is complete.

Note 4)

In the automatic operation mode, batch processing cannot be executed.

Note 5)

Controller operation which are effective in a batch processing are as follows:

EMERGENCY STOP, SERVO ON, and SERVO OFF

Note 6)

Commands specified for batch processing are immediately processed without any prompt to the

operator such as "Press Y key to delete the file".

In a batch file, commands of the controller should be listed in the order of the execution. For

details of how to edit a file, see 3.2, "Changing File Data".

Any batch file is executed by entering its name (without the extension) from the teach pendant

just like with any command.

LOADPRO3

LOADPRO4

LOADPROS

LOADPRO6

To execute the above batch file, enter the following from the teach pendant.

[F] [L] [O] [A] [D] [Exec]

When the batch processing is executed, the controller reads the file PRO1 to PRO6 from a

floppy disk to the RAM drive in the controller.

Note 1)

In the external automatic mode, batch files cannot be executed from the teach pendant.

Note 2)

As opposed to selecting a program, batch files cannot be selected or executed using external

input signals.

Note 3)

Unless a batch file is in the controller RAM drive, it cannot be executed.

3.5.2 Automatic Execution File

A batch file which is executed just after the controller power is turned on is called an automatic

execution file. The contents of the automatic execution file are just like any other batch file,

although the file name of the automatic execution file is AUTOSTR. BAT.

The automatic execution file can be used to select a file in the external automatic mode. For

details of how to edit files, see 3.2, "Changing File Data".

Example)

To select a file which is to be executed just after the power is turned on in the external

automatic mode:

File name: AUTOSTR.BAT

SELECT PRO1

In order to execute the above automatic execution file, it must first have been stored in the RAM

drive of the controller and the MASTER MODE KEY switch on the control panel must have

been placed in either the "INT" or "EXT" position. In this situation, after the power of the

controller is turned on and the hot start operation is complete, file PRO1 is selected as a file to

be executed.

Note)

When the MASTER MODE KEY switch is in the "MANU" position, when the controller power is

turned on, a program will not be selected because an execution of the SELECT command

results in an error.

3.5.3 Using Batch Processing Effectively

Batch processing is effective for executing a predetermined process by pushing just a few keys.

For example, when a process which reads files stored on a floppy disk to the controller is

described as a batch file, all the required files can be read by just running the batch file.

Likewise, when replacing a file in the controller with another file to change system operation, a

prepared batch file corresponding to the system change can be readily executed.

Example)

When reading files stored on a floppy disk into the controller after a cold start, the files to be

read in and a batch file can be stored on the floppy disk in advance.

File name: ALOAD. BAT

and any program files whose extension is ".PRO" to be read to the RAM drive of the controller.

Note)

Save files on a floppy disk other than the system disk. To prevent the contents of the system

disk from being accidentally altered, it is strongly recommended to place the write protect tab of

the floppy disk in the write disable position.

3.6 PROGRAM EXECUTION ENVIRONMENT

3.6.1 Program Execution Environment

The following items are conditions for automatically operating a program.

Execution file

①

A file for automatically operating the robot. Normally, this file is selected by using the

"SELECT" command in the internal automatic mode.

In the external automatic mode, the execution file can be selected by using an external control

signal.

Execution step

②

A step for executing a program. Even if the automatic operation of the program is stopped, the

program can be executed from the subsequent step.

Variables

③

Variables used in the program.

Digital output signals

④

Output signals for synchronously operating a robot language program and peripheral units.

Basically, the output signals are specified by the robot language program.

Once the signal is output, it is kept on until the off command is executed.

When the power is turned off, the signal is turned off. When the power is turned on, all the

output signals are in the off state.

Auxiliary output signals

⑤

Signals for controlling an end effector such as a hand. Basically, the auxiliary output signals are

specified by the robot language program.

Once the signal is output, it is kept on until the off command is executed.

When the power is turned off, the signal is turned off. When the power is turned on, all the

output signals are in the off state.

STE 58760

Operation modes

⑥

There are three operation modes; step, cycle, and continue. The step operation mode can be

selected only in the test operation mode. In the internal operation mode, the operation mode

is selected by the "MODE" command or by the "CYCLE STOP" switch on the control panel.

In the external automatic mode, the operation mode is selected by an external control signal.

⑦ Speed override (MSPEED)

The speed of the automatic operation is decreased in the entire program.

The speed override is set by the "MSPEED" command in the internal automatic mode or in the

test operation mode. Even if the mode is changed, the setting value is stored.

When the power is turned on, the speed override is set to 100%.

Speed limit (LSPEED)

⑧

A speed limit in the automatic operation.

The speed limit is set by the "LSPEED" command in the internal automatic mode or in the test

operation mode. Even if the mode is changed, the setting value is stored.

In the test operation mode, the speed limit is limited to 25%. In addition, with the low speed

command signal, which is an external control signal, the speed limit is restricted to 25%.

When the power is turned on, the speed limit is set to 100%.

Machine lock

⑨

A function for executing the automatic operation without operating the robot. The machine lock

is available only in the test operation mode. It can be set by using the "MACHINE" command.

When the power is turned on, the robot is not in the machine lock state.

Coordinate system

⑩

A coordinate system for operating the robot is set. For details, see 3.7, "SETTING

COORDINATE SYSTEM."

Only ① to ③ above are stored as the program execution environmental data.

The coordinate system being set is not initialized even if the program is hot-started.

Other items are initialized when the program is hot-started.

3.6.2 Resetting Execution Environment

To reset the execution environmental data of the program, the "RESET" command can be used.

The "RESET" command can be used in the manual mode or in the internal automatic mode. In

the external automatic mode, an external control signal has the same function as the "RESET"

command. For details of the external control signal, see "INTERFACE MANUAL."

To execute the "RESET" command, select "RESET" by using the function key, specify a desired

data item by using the alphanumeric keys, and then press the "Exec" key.

The following are reset types.

Program reset (RESET PROG)

①

Initializes all execution environmental data of the program. The execution step of the program

is placed at the beginning of the program. All variables are initialized.

Step reset (RESET STEP)

②

Only the execution step of the program is placed at the beginning of the program. The

variables are not initialized.

③ Cycle reset (RESET CYCLE)

The execution step of the program becomes a step with label "RCYCLE." The variables are

not initialized.

Output signal reset (RESET SIG)

④

3.7 SETTING COORDINATE SYSTEM

A coordinate system can be set according to the application of the robot.

When the robot is guided to an actual operation position and the position is taught to the robot, it is

not necessary to set a coordinate system.

When a coordinate system is set unintentionally, the teaching operation of the position becomes

complicated. Unless otherwise required, it is recommended to operate the robot in the initial state

without setting a coordinate system.

A coordinate system should be set in the following cases.

To manually guide the robot along a coordinate system other than the base coordinate

system.

①

To represent an operation position by means of a relative position of a workpiece when the

same operation is conducted for two or more workpieces.

②

③ To perform a linear interpolation/circular interpolation in accordance with the edge of the

tool.

④ When the installation position of the robot is changed, to use the position data which was

used in a previous operation.

3.7.1 Robot Coordinate Systems

The robot has five coordinate systems; world coordinate system, base coordinate system,

work coordinate system, mechanical interface coordinate system, and tool coordinate system.

World coordinate system (absolute coordinate system)

①

A coordinate system intrinsic to the operation place where the robot is installed. The world

coordinate system can be set regardless of the robot. Generally, a coordinate system where

the installation reference point of the robot is the zero point is selected (namely, the base

coordinate system is selected).

Base coordinate system (machine coordinate system)

②

A coordinate system intrinsic to the robot. This coordinate system is intrinsic to the structure of

the robot. Generally, the installation reference point of the robot becomes the zero point.

STE 58760

Work coordinate system (operation coordinate system)

③

A coordinate system intrinsic to work for which the robot is operated. The zero point of the

work coordinate system is set at the reference point of the work. It is also determined by the

operation of the robot.

Mechanical interface coordinate system

④

A coordinate system in which the position of an end effector of the robot is set to the zero point.

As the robot is moved, this coordinate system is accordingly moved.

⑤ Tool coordinate system

A coordinate system where the end of an end effector of the robot is set to the zero point.

As the robot is moved, this coordinate system is accordingly moved.

The base coordinate system and the work coordinate system are set in accordance with the

world coordinate system.

The tool coordinate system is set in accordance with the mechanical interface coordinate

system.

(The base coordinate system and the mechanical interface coordinate system are determined

only depending on the mechanism of the robot. The world coordinate system is relatively

determined by setting the base coordinate system.)

In the initial state where the coordinate system has not been set, the world coordinate system

and the work coordinate system accord with the base coordinate system, while the tool

coordinate system accords with the mechanical interface coordinate system.

3.7.2 Teaching Coordinate Data

When setting and using a coordinate system, it is necessary to teach coordinate data for giving

the coordinate system.

(1) Coordinate data

Coordinate data are data for giving a new coordinate system by means of an original coordinate

system.

Coordinate data are structured as follows.

(Coordinate data name) = X, Y, Z, C

Coordinate data name

X, Y, Z

: A name representing coordinate data with up to 10 characters

starting with an alphanumeric character.

: X, Y, and Z axis values of the zero position of the new coordinate

system viewed from the original coordinate system (unit: mm).

: Amount of rotation around axis Z between the new coordinate

system and the original coordinate system (unit: deg).

The new coordinate system is that the original coordinate system is horizontally moved for axes

X, Y, and Z and then the original coordinate system is rotated for C around the new axis Z.

(2) Teaching coordinate data

Like position data, coordinate data are taught to individual files. There are three teaching

methods;

numeric value input method,

one-point teaching method and

two-point

teaching method.

The coordinate data are taught in the following manner.

When coordinate data are substituted into system variables TOOL and BASE in the robot

language, after the existing operation is completed, the selected coordinate becomes valid

(the short cut operation is cancelled).

When coordinate data are substituted into system variables TOOL and BASE by using

WITH clause in the robot language, the coordinate system is selected before the existing

operation is completed.
