VM24 I/O Module

Overview — VM24
The VM24 external I/O modules act as an interface for the general-purpose
programmable inputs and outputs of all the 6000 Series servo and
microstepping products. The VM24 module consists of a base board and one
to three SIM (single in-line module) style boards that can be inserted to
provide the user with a scaleable solution for their input and output needs.
• The outputs are enhanced by an undervoltage lockout circuit and a
thermal shutdown protection circuit. These outputs operate over 5VDC
to 24VDC, will sink 50 mA to 0.4VDC or 300mA to 2.5VDC, and
will source 50 mA to a voltage level of V – 2VDC (user-supplied
o
voltage level V minus 2 volts, e.g. for V =24V, output is 22V) or
o
o
300 mA to a voltage level of V – 2.5VDC (user-supplied voltage
o
level V minus 2.5 volts, e.g. for V =24V, output is 21.5V).
o
o
• The inputs are enhanced by decompression, hysteresis, high-frequency
filtering, and overvoltage clamping. These inputs, capable of operating
in sinking or sourcing mode, have a range from 5VDC to 24VDC. The
switching level for inputs is based on the user-supplied voltage V , such
i
that OFF ≤1/3 (V ) and ON ≥ 2/3 (V ), with hysteresis of 1/3(V ).
i
i
i
(For example, with V of 24VDC, OFF ≤ 8VDC and ON ≥ 16VDC,
i
with 8VDC of hysteresis.) Jumpers are used to configure the inputs as
sinking or sourcing. Each of the three SIM sockets has its own
corresponding jumper, allowing each input SIM to be independently
configured.
The VM24 module accepts a 50-pin ribbon cable from the 6000 Series
product and provides screw terminal connections for easier interface with the
user's application. The 24 I/O signals to/from the 50-pin DIN connector and
the 50-pin screw terminal are interrupted by three SIM sockets (each SIM
interrupts an 8-bit group of signals).
Optical isolation is inherited from the 6000 product, except for OEM
products. (I/O ground is isolated from microprocessor ground, but inputs and
outputs are not isolated from each other.)

Undervoltage
Protection.........The under-voltage lockout circuit is meant to
prevent the output driver from sinking or sourcing
unless the user-supplied voltage V is between
o
5VDC and 24VDC.
Thermal Shutdown....The thermal shutdown protection is intended to
protect the device from marginal environmental
factors. It must not be considered short circuit
protection. The thermal resistance between the
FET junction and the thermal protection circuit
on the SIM cards is great enough that the rapid
rise in junction temperature caused by a short
circuit will not transfer fast enough to protect the
device from damage.
+5V Output.............Supplied by the 6000 Series Controller/Indexer
through the 50-pin ribbon cable to connector J4.
Accessed on the VM24 through the screw
terminals (J5). Refer to the User/Installation
Guide for the 6000 Series Controller/Indexer
being used for the load limit of its +5V Output.
Subtract any loads being drawn from the +5V
Output at the 6000 Series unit level. The VM24
draws 0.25mA per active output and 0.5mA per
active input from the +5V supply. Use this
information to calculate the load limit available
for the +5V Output on the screw terminal of the
VM24.
NOTE: Outputs are not short-circuit protected.

Ribbon Cable Connection
Caution
Remove power to the VM24 before
attaching or removing the cable.
The VM24 is shipped with a 2-foot ribbon cable, with mating connectors.
Connectors are keyed to ensure that they are inserted into mating connectors
correctly. Cable installation for the VM24S, VM24-IN, and VM24-OUT
consists of simply inserting the connector from one end of the cable into the
Programmable I/O connector of the 6000 Series Controller/Indexer, then
inserting the connector at the other end of the cable into connector J4 of the
VM24.
Multi-axis 6000 Series Controller/Indexers have separate input and output
connectors. Therefore, the two multi-axis configurations of the VM24
which offer both inputs and outputs, listed below, require a split cable to
access both of these connectors.
• VM16/8
• VM8/16
The connector that is attached to the portion of the ribbon cable with the red
stripe corresponds to the I/O boards in sockets J2 and J3 — either 16 IN or
16 OUT. This connector should be inserted into its corresponding Input or
Output connector on your 6000 Series Controller/Indexer. See Figures 6 and
7. The connector that is attached to the smaller width of ribbon cable
corresponds to the I/O board in J1 — either the SIM8-IN or SIM8-OUT.
This connector should be inserted into its corresponding Input or Output
connector on your 6000 Series Controller/Indexer.

VM24 Module Configuration Summary
The VM24 is shipped with the SIM8 boards already installed.
1. Mount the VM24 module (standard DIN rail).
2. Set the jumpers to position 3 (default) for sinking inputs or to position
1 for sourcing inputs. (See page 11).
3. Connect the 50-pin ribbon cable to the I/O connector(s) of the 6000
Series Controller/Indexer (see page 12). Connect the other end of the
cable to the J4 connector of the VM24 module. Make sure that power is
off to the 6000 Series unit before making these connections because the
50-pin ribbon cable provides +5V to the VM24 from the I/O connector.
4. Connect the output pull-up pin OUT-P of the 6000 Series unit to V
(J6) of the VM24 module. This ensures the proper sequencing of
outputs upon application of power. Make sure the jumper
between OUT-P and +5V on the 6000 Series unit is
removed to avoid damage to the VM24. (This step is not
necessary for the VM24-IN.)
o
5. Connect the desired power supply to V at connector J6. Do not apply
o
power until all connections are made. (This step is not necessary for the
VM24-IN.)
6. Connect the desired power supply to V at connector J6. Do not apply
i
power until all connections are made. (This step is not necessary for the
VM24-OUT.)
7. Make connections to the desired input and/or output signals using the
screw terminals. (J5). See Pin-Out Table on page 8.
8. Apply power to the VM24 module. The power-up sequence is not
important as long as OUT-P is connected to V .

Basic Troubleshooting
When your system does not function properly (or as you expect it to
operate), the first thing that you must do is identify and isolate the problem.
When you have accomplished this, you can effectively begin to resolve the
problem.
•
Is the 50-pin ribbon cable connected properly to the 6000 Series
Controller / Indexer? If it's a split cable, is the input connector of the
cable connected to the input connector of the 6000 Series unit? Is the
output connector of the cable connected to the output connector of the
6000 Series unit? (See pages 12-14.)
•
•
•
•
•
Is the 50-pin ribbon cable connected properly to connector J4 of the
VM24?
Is the OUT-P pin on the 6000 Series Controller/Indexer connected to
V ? (Not applicable for the VM24-IN.)
o
Is the IN-P pinon the 6000 Series Controller/Indexer connected to +5V
(or other power supply)? (Not applicable for the VM24-OUT.)
Are the V and V power supplies connected to the VM24? See pages
o
i
4 and 10.
Are the voltage values and polarities correct for V and V ? (The
o
i
output circuitry of the SIM8-OUT and SIM8-4X4 cards are susceptible
to damage from improperly applied power. The VM24 is not short
circuit protected.)
•
•
Are the jumpers set properly to select sinking or sourcing mode for the
inputs? (Not applicable for the VM24-OUT.) See page 11.
Are the input and output devices connected to the proper inputs or
outputs on the screw terminal (J5). Verify with the I/O pin out table
on page 8.
•
Is the +5V Output load limit being exceeded? (Any connections to the
+5V Output on the screw terminal [J5]? Any connection to the +5V
Output on the 6000 Series unit? See the Specification Summary on
page 6 for how to calculate the load limit.)
•
•
Are the SIM8 boards installed in the proper slots? (See page 9.)
Are the SIM8 boards seated properly in their designated slots? (See pg.
23.)

6000 Series Controller/Indexer
First, verify that 6000 Series Controller/Indexer I/O is functioning properly
to aid in isolating the problem. Disconnect the 50-pin ribbon cable, or just
disconnect the cable from connector J4 of the VM24, before performing this
test.
Outputs:
Use the Transfer Output Status (TOUT) command to check the status
of the outputs. Use the Output State (OUT) command to change the
outputs. Use a voltage meter to check individual outputs at the I/O
connector of the 6000 Series unit to verify that the voltage level
toggles between Ground and V .
o
Inputs:
Use the Transfer Input Status (TIN) command to check the status of
the inputs. Use the Input Active Level (INLVL) command to define
the active state of all programmable inputs. Alternate between
applying supply voltage V to an input and grounding it, using the
i
TIN command to verify that the input toggles as you do so.
If the inputs or outputs do not appear to be functioning properly at
the 6000 Controller level, refer to the Common Problems &
Solutions section of the Troubleshooting chapter in the User Guide
or Installation Guide for the 6000 Series Controller/Indexer being
used in the application. Specific I/O problems are addressed in the

50-pin Ribbon Cable
Next, verify that the ribbon cable is relaying the signals properly. Connect
the 50-pin ribbon cable to the 6000 Series unit, but do not connect the other
end of the cable to the VM24. Repeat the above test, applying and checking
voltages at the connector that would plug into J4. (The red stripe on the
ribbon cable corresponds to pin 50 on the 6000 Series Controller/Indexer I/0
connectors.)
As an alternative, disconnect the 50-pin ribbon cable from the 6000 Series
unit and the VM24. Use a volt meter and a voltage source to verify the
continuity of the 50-pin ribbon cable.
VM24
Caution
Remove power to the VM24 before
making any connections. Remember to
turn off power to the 6000 Series unit
before connecting the 50-pin ribbon
cable to the VM24. (The ribbon cable
provides +5V to the VM24 from the
6000 Series unit I/O connector.)
Once it has been verified that the 6000 Series unit and 50-pin ribbon cable
are operating properly, check the VM24 to isolate the problem. Reconnect
the 50-pin ribbon cable to the 6000 Series, and the other end to connector J4.
Turn on power.

Use a volt meter to verify the voltage level of the +5V output on
the screw terminal block (J5). (The +5V is supplied by the 6000
Series unit, and is used to power the input and output circuitry on
the SIM8 cards.)

Outputs
Use the Transfer Output Status (TOUT) command to check the status
of the outputs. Use the Output State (OUT) command to change the
outputs. Use a voltage meter to check individual outputs at the
screw terminals (J4) of the VM24 to verify that the voltage level
toggles between Ground and (V -2). [The output level should be
o
approximately 2 volts less than the user supplied voltage V .]
o
If one output does not appear to toggle, check all other outputs. If
none of the outputs will toggle, check V again. If some outputs
o
will toggle, and some won't (after verifying that they toggle
properly at the 6000 Series unit I/O connector), the corresponding
SIM8-OUT or SIM8-4X4 board isn't seated properly or has been
damaged. (See page 9.)
Inputs
Use the Transfer Input Status (TIN) command to check the status of
the inputs. Use the Input Active Level (INLVL) command to define
the active state of all programmable inputs. Alternate between
applying supply voltage V to an input and grounding it, using the
i
TIN command to verify that the input toggles.
If one input does not appear to toggle, check all other inputs. If
none of the inputs will toggle, check V again. If some inputs will
i
toggle, and some won't (after verifying that they toggle properly at
the 6000 Series unit I/O connector), the corresponding SIM8-IN or
SIM8-4X4 board isn't seated properly or has been damaged. (See
page 9.)
SIM Board Insertion and Removal
In the event that an I/O board needs to be replaced, the I/O boards must be
inserted and removed from the VM24 in a particular order due to the limited
clearance between the sockets. Remove all power to the VM24
before removing or inserting an I/O board, including the +5V from
the connection to the 6000 Series Controller/Indexer at connector J4. When
removing I/O boards, remove the board from the J1 slot first, J2 second, and
then J3. When inserting I/O boards, insert the board into the J3 slot first, J2
second, and then J1.
