Chapter 2 Faults and Troubleshooting
Introduction
The drive software includes selftest diagnostics to aid in troubleshooting. When
these tests detect an unfavorable condition, they output fault indications to the
drive’s operator interfaces: the door-mounted Drive Diagnostic Interface (DDI,
referred to as the keypad) or a connected PC running the GE Control System
Toolbox (the toolbox). An operator can then use either interface to examine the fault
and clear it, as applicable.
For information on using the
keypad refer to the drive
User's Guide, GEH-6382.
GEH-6401 describes the
toolbox.
This chapter lists and defines the relevant fault messages for the drive, with
troubleshooting suggestions. It is organized as follows:

Chapter 2 Faults and Troubleshooting • 2-1
Types of Faults
There are currently two types of fault conditions:
•
Alarm faults indicate conditions that you should note, but that are not serious
enough to automatically shut down or trip the drive. If the condition goes away,
some alarm faults clear themselves and the display then identifies the alarm as
brief. Otherwise, you must stop the drive to clear this type of fault.
•
Trip faults indicate a more serious condition that needs to be corrected.
Therefore, it trips the drive. The drive should not be restarted until the condition
is corrected.
You can clear most faults by selecting Clear Faults on the drive’s keypad or in the
(optional) toolbox program.
Fault Indication
The drive indicates a fault condition on the keypad, toolbox display, and on the
DSPX board.
The DSPX board is the
IS200DSPX Digital Signal
Processor, located in the
drive control rack.
On the keypad, a fault icon appears in the right side of the display: The operator can
then use the keypad to access the fault/alarm description (see Figure 5-1) and to clear
the fault.

Figure 2-1. Sample Fault Display Screen on Keypad
The toolbox uses a Windows -based PC display. When a fault occurs, the word
Alarm or Trip appears in the lower right corner of the screen. You can view a
description and clear the fault using the toolbox functions. (GE publication GEH-
6401 describes these tools and this feature.)
The DSPX Fault LED displays at the front of the drive’s control rack. This red
indicator is on solid for a fault and flashes for an alarm.
A fault is identified by an assigned number and abbreviated description. Both of
these are displayed when an operator examines a fault using the keypad (see Figure
2-1) or the toolbox.
Table 2-1 lists the drive faults and their probable cause.

1 CPFP isolation lost
Type Description
Trip
The CPFP isolation lost trip fault is hardware generated. The CPFP power
supply isolation card is indicating that power supply isolation to the phase
modules has been compromised. The CPFP card is designed to provide
control power to circuit cards in the high voltage compartment. This card has
a double voltage barrier that isolates the phases from each other and from the
control. This fault indicates that one of these voltage barriers has failed. This
is a dangerous situation since failure of the second barrier could cause
dangerous voltages to conduct into the control cabinet or cause a phase-
phase short on the CPFP card. The fault is generated when the status light
conducted via fiber from the CPFP goes out. The fiber connects CPFP (PWR
OK) to FOSA (SPARE-R). Check that the fiber is installed correctly.
Disconnect the fiber from FOSA and look for the status light traveling up the
fiber. If you do not see a light then the problem is on CPFP. If there is light
then the problem is on FOSA or BICM.
Primary causes:
CPFP power supply failure
Fiber not connected
Possible board failures:
CPFP
FOSA
BICM
Possible wiring faults:
Power distribution wiring to CPFP.
2
Illegal seq state
Trip
The Illegal seq state trip fault occurs when the sequencer state (variable
Sequencer state) is unrecognized. This trip may occur during system
development but should not occur in the field.

No. Name
Type Description
The Cont failed to close trip fault occurs when contactor A is commanded to
3 Cont failed to close Trip
open or close and fails to do so within the allowed time (defined by parameter
MA pickup time).
Primary causes:
The contactor A feedback is missing or bad.
Possible configuration faults:
The allowed time for contactor A to open and close is too short. The allowed
time is represented by parameter MA pickup time.
Contactor A feedback is enabled when no contactor is present in the system.
In the absence of the contactor, parameter MA contactor fbk should be set
equal to Disable.

Local flt
Trip
Trip
The Local flt trip fault occurs when the local permissive circuit is open and a
Run request, Jog request, Full flux request, or diagnostic test (cell test, pulse
test, autotune) request is issued.
Possible wiring faults:
The connections to ATBA terminal board locations 8 (L115), 10 (L24), and 12
(LCOM) are missing or damaged.
The connection to backplane connector J2 is missing or damaged.

6
Tool requested trip
The Tool requested trip trip fault is generated from the engineering monitor
issuing the “uf” command. It is for test purposes only.
Run cmd during init Alarm
The Run cmd during init alarm occurs when a Run request, Jog request, Full
flux request, or diagnostic test (cell test, pulse test, autotune) request is issued
during drive initialization. When the alarm occurs, the request to perform a
drive action is ignored.
Primary causes:
The external application layer issues a request to perform a drive action during
drive initialization.
An external input (i.e. digital input) used to request a drive action was high
during drive initialization.
7
Over speed
Trip
The Over speed trip fault occurs when the magnitude of speed (variable
Speed reg fbk) is greater than the over speed threshold (parameter Over
speed flt level).
Primary causes:
Motor speed is too high.
Possible configuration faults:
Parameter Over speed flt level is set too low.
Related functions:
Speed Control Fault Check

Timed over current
EE flash corrupted
Trip
Trip
The Timed over current trip fault occurs when one of the squared phase
currents (variables Ia^2 filtered, Ib^2 filtered, and Ic^2 filtered) in the timed
over current detection model exceeds the timed over current threshold level.
This fault indicates that the motor has exceeded its thermal limit.
The EE flash corrupted trip fault occurs when the memory containing the drive
parameters is determined to be bad during drive initialization.
EE flash corrupted requires a hard reset to clear.
Possible board failures:

The Run cmd w high flux alarm occurs when a Run request, Jog request, Full
flux request, or diagnostic test (cell test, pulse test, autotune) request is issued
and the variable Flux reference is greater than 2 percent rated flux (100%
Flux).
Primary causes:
An attempt is made to restart the drive quickly. Normally four rotor time
constants are required to allow the flux to decay after the drive stops running.

EE erase failed
Alarm
The EE erase failed trip fault occurs when the preparation of memory for the
next parameter save operation fails to happen satisfactorily. The next
parameter save operation is expected to be invalid, and the integrity of future
parameter save operations are in doubt.
EE erase failed requires a hard reset to clear.
Possible board failures:
DSPX

13
Gnd flt, coarse
Trip
The Gnd flt, coarse trip fault occurs when a large ground current is detected.
The trip fault occurs when the magnitude of the sum of the three phase
currents is too large.
Vdc Fbk voltage
trim
Alarm
The Vdc Fbk voltage trim alarm occurs when the automatic Vdc feedback trim
function on the BICM is not functioning correctly. You will not receive this
warning unless you are using drive firmware version V02.21.00B or higher
AND you have a BICMH1AB version card or higher. Older versions of
software and hardware suffer from Vdc feedback inaccuracy, which can lead
to problems in some circumstances. Getting the trim function to operate
properly is important to optimum performance of the drive. There are several
situations that can lead to this alarm.
First, make sure you have run the Cell Test Wizard (either fiber optic test or
bridge cell test) at least once when the DC link is fully discharged (<100V).
This wizard calibrates the DC bus feedback and saves a parameter in the
drive. This procedure does not need to be repeated unless hardware has
changed in the drive or the previously saved parameter was overwritten by a
parameter downloaded from the toolbox. If this procedure has not been
performed then this alarm is generated.
Second, make sure that JP1 on the BICMH1AB card has been moved to the
non-default position. This jumper enables the circuit that this alarm is
concerned with. The jumper JP1 being in the dashed-box indicates the non-
default position. The jumper being in the solid box indicates the default
position. The default position is used only when the card is placed in drives
that have software versions prior to V02.21.00B
If both if these steps fail to clear this alarm then your BICM card may be
defective.

107 Motor volt offs high
Alarm
The Motor volt offs high alarm occurs when the line-line voltage offset
measurements are invalid when the drive is started. Generally the alarm
occurs when the drive is stopped and quickly started again.
The voltage offsets are represented by variables A-B, Voltage offset and B-C,
Voltage offset. They are the outputs of automatic voltage offset
measurements. They are valid for a certain length of time after the
measurements are performed.
The voltage offset measurements are performed when the drive is started and
enough time has elapsed to cause the previous voltage offset measurements
to be invalid. However, there is an exception to this statement. The offset
measurements are not performed during the flux decay time, which begins
when the drive is stopped and continues for 8 rotor time constants.
When the drive is started during the flux decay time, and the previous offset
measurements are invalid because too much time has elapsed since they
were performed, the Motor volt offs high alarm occurs.

135 AC line transient
Alarm
The AC line transient alarm occurs as a result of significant phase lock loop
error or significant phase imbalance.
A phase imbalance signal is calculated by subtracting a control calculated
threshold from a filtered signal which is formed by filtering the sum of two
signals. One of these signals is the phase lock loop error and the other is the
error between the demodulated real component of line voltage and the
measured magnitude of the line.
The calculated threshold phase imbalance level which is computed by the
control is based on the magnitude of the input line voltage. This calculated
phase imbalance threshold represents a phase imbalance of about 18% or a
phase lock loop error of about 6.7 degrees. The phase imbalance signal
which is a result of the previously mentioned subtraction is equal to about
18% imbalance when it becomes positive.
The phase imbalance signal feeds an integrator designed to cause the AC line
transient alarm when the threshold has been exceeded for a very short time.
That amount of time is dependent upon the amount of the phase imbalance,
but the alarm will occur eventually if the imbalance signal remains positive.
Primary causes:
AC line disturbances.
Transient phase imbalances.
Weak control of frequency on diesel generator sets or gas turbine generator
sets.
Very fast voltage magnitude changes.

137 AC line rev phs seq Trip
The AC line rev phs seq trip fault occurs when the control senses that the
rotation of the AC line is opposite of what is expected. This condition is
checked only one time after the control is powered up. When the phase lock
loop locks for the first time, just after the charging sequence has begun, the
sign of PLL frequency is checked against the expected sign. The expected
sign is determined by the setting of Phase rotation req. If Forward sequence
is selected, the sign of PLL frequency is expected to be positive, otherwise, it
must be negative. If the expected sign is not found, the trip fault is given. AC
line rev phs seq requires a hard reset to clear.
Before changing Phase rotation req, review the rotation of any AC cooling
pumps or blowers in the drive. Incorrect phase sequence can lead to
ineffective air or water flow in the cooling system.
Primary causes:
Control senses wrong phase sequence.

149 Sat curve data bad
The Sat curve data bad trip fault occurs when the flux saturation curve is not
monotonic.
Primary causes:
The saturation curve data entered by the operator is bad.
The saturation curve data calculated by autotune is bad.
Possible configuration faults:
One or more of the saturation curve parameters is bad. The saturation curve
parameters are Flux curve amps 1, Flux curve amps 2, Flux curve amps 3,
Flux curve amps 4, Flux curve amps 5, Flux curve voltage 1, Flux curve
voltage 2, Flux curve voltage 3, Flux curve voltage 4, and Flux curve voltage 5.
150 Rated flux data bad Trip
The Rated flux data bad trip fault occurs when the motor control calculation of
rated flux (variable 100% Flux) does not converge to a stable value.
151 Leakage curve bad Trip
The Leakage curve bad trip fault occurs when the leakage flux curve is not
monotonic (i.e. Point 1 < point 2 < point 3 < point 4 < point 5).
Primary causes:
The calculated leakage curve has been derived from bad motor reactance
data.
The leakage curve data entered by the operator is bad.
The leakage curve data calculated by autotune is bad.
Possible configuration faults:
When the leakage curve is not entered specifically point-by-point (see below)
one is calculated from Starting react Xst, Magnetizing react Xm, Stator lkg
react X1, and Rotor lkg react X2. The relationship between these parameters
should be: (Rotor lkg react X2 || Magnetizing react Xm) + Stator lkg react X1
> Starting react Xst. If Motor reac parms bad fault is also present, this is the
likely cause.
When the leakage curve is not entered specifically point-by-point, one or more
of the leakage curve parameters is bad. The leakage curve parameters are
Lkg flux current 1, Lkg flux current 2, Lkg flux current 3, Lkg flux current 4, Lkg
flux current 5, Lkg flux voltage 1, Lkg flux voltage 2, Lkg flux voltage 3, Lkg flux
voltage 4, and Lkg flux voltage 5. If the leakage parameters are not set, the
leakage curve is determined as above, or as the results of autotune.

Capture Buffer
The Innovation Series capture buffer is used to collect coherent data at a specified
rate in the drive. The capture buffer is circular, and will collect a fixed number of
samples of each data channel before overwriting the oldest data. The capture buffer
can be triggered on any available variable signal in the drive by using a Boolean
trigger mode or comparison to a value. The capture buffer will also trigger on a Trip
fault. It is useful for capturing drive variables for troubleshooting field problems and
capturing specific drive events. The Trend Recorder can display the capture buffer
output.
Function Inputs
The following table specifies the input parameters to the Capture Buffer function.

GEH-6385 Reference and Troubleshooting, 2300 V Drives
Chapter 3 Paramters/Functions • 3-5
Function Configuration
The following table specifies the parameters that configure the size and execution
rate of the capture buffer.
Parameter
Description
Capture buff config
Specifies the number of channels to collect. The depth
of the capture buffer is inversely proportional to the
number of channels collected. Possible values are:
2 channels enabled
4 channels enabled
8 channels enabled
Note Whenever this parameter is modified, the
capture buffer must be re-enabled to collect data with
the new channel configuration.
Capture period
Determines the rate at which the capture buffer collects
data. Each rate in the enumeration list is based on a
particular execution rate in the processor. Actual
execution rates vary between each Innovation Series
product. Possible values are:
Disable - Disables the capture buffer from collecting
data.
Task 1 rate - Collects data at the fastest execution rate
of the processor.
Task 2 rate - Collects data at n times slower than Task
1 rate. (n Task 1’s are executed every 1 Task 2).
Task 3 rate - Collects data at m times slower than Task
2 rate. (m Task 2’s are executed every 1 Task 3).
Note Whenever this parameter is modified, the
capture buffer must be re-enabled to collect data at the
new rate.
Capture period gain
Cap re-enable delay
Increases the collection period of the capture buffer
(data is collected at a slower rate). For an integer
value, n (>1), the capture buffer would collect data
every nth execution of the Capture period.
Controls an auto re-enable function for the capture
buffer. This parameter sets the delay from when the
capture buffer has completed its collection to when the
capture buffer is re-enabled automatically. Minutes.
The capture buffer will only re-enable when the drive is
not stopped (Stopped is False). If Cap re-enable delay
expires when the drive is stopped, the capture buffer
will not re-enable until the drive is running again.
Note A value of –1 disables the auto re-enable
function.

Capture Buffer Compatible Behavior
To view more than 4 channels or more than 512 samples, the Capture Buffer
function should be used with a GE Control System Toolbox with a release of at least
V6.1. Toolbox version prior to the V6.1 release can handle a maximum capture
buffer size of 4 channels x 512 samples.
The capture buffer will present the collected data in a backward compatible format if
used in conjunction with an older Toolbox release, however, because the capture
buffer size has increased, only a sub-set of the data will be presented when viewed
with an older Toolbox.

General Purpose Constants
Each Innovation Series product provides three general purpose constants. The
general purpose constants allow users to place constant values in device variables.
The general purpose constants are particularly useful in configuring diagnostic
functions.
Function inputs
The following table specifies the input parameters of the General Purpose Constants
function.
Parameter
Description
GP Constant 1
GP Constant 2
GP Constant 3
User defined constant 1
User defined constant 2
User defined constant 3
Function outputs
The following table specifies the output variables of the General Purpose Constants
function.
Variable
Description
GP Constant 1
GP Constant 2
GP Constant 3
User defined constant 1
User defined constant 2
User defined constant 3
Function description
The General Purpose Constants function sets the general purpose constant output
variables equal to the general purpose constant input parameters:
GP Constant 1 = GP Constant 1
GP Constant 2 = GP Constant 2
GP Constant 3 = GP Constant 3
The units of the general purpose constants are determined by their use. For example,
if one of the constants is used as a comparison level in a diagnostic function such as
an SLD, the implied units of the constant are the internal control units of the signal
against which the comparison is made. The units of the general purpose constant are
not necessarily the display units of the comparison signal. For more information on
the difference between display units and internal control units, see the Language and
Units Presentation function help.

GEH-6385 Reference and Troubleshooting, 2300 V Drives
Chapter 3 Paramters/Functions • 3-11
The general purpose filters run at the fastest execution rate available in the product.
This is the same rate at which bridge feedbacks are collected, the fastest regulators
are operated, and hardware commands are issued. The filter execution rate is
generally faster than the 1-millisecond rate at which the application functions and the
LAN communications occur.

Function description
The output signals Position counter and Pos cntr mark are the tachometer position
and the marked tachometer position extended from 16 to 22 bits. Position counter
and Pos cntr mark roll over to zero (0) at the maximum value that can be represented
in 22 bits (4,194,303). The transition happens in both the forward and backward
directions.
Position counter is sampled when the signal selected by Pos sample cmd sel
transitions between True and False. Pos up edge sample equals Position counter
when the signal selected by Pos sample cmd sel changes from False to True. Pos
down edge smp equals Position counter when the signal selected by Pos sample cmd
sel changes from True to False.
The Task Interval Strobe shown on the Position Feedback diagram represents
sampling of hardware that takes place at the Task 1 rate, the fastest execution rate
available to the control. The Task 1 rate is faster than the fastest rate at which
Position counter can be sampled.

Variable
Description
AC line voltage mag
Filtered ac line magnitude. A true magnitude calculation
of Vab and Vbc which is then filtered.
AC line frequency
Filtered ac line frequency produced by the phase lock
loop.
Line Simulator
The Line Simulator function allows the user to simulate the operation of the drive
and the ac line without applying power to the bridge.
Function inputs
The following table specifies the input parameters of the Line Simulator function.
Parameter
Description
Sim line frequency
AC line frequency in simulator mode. It is normally set
to, but not restricted to, 50 or 60 Hertz.
Sim freq slew rate
Sim A-N volt scale
Simulator frequency slew in radians/sec/sec. Setting
this value to a something other than zero causes the
frequency to slew continuously from (-)0.5 of nominal to
(+)0.25 of nominal and back. This exercises the entire
transient frequency range covered by the specification.
Sim A-N volt scale can be used to attenuate phase A
line to neutral voltage in order to simulate transient line
conditions. The line to neutral voltage for phase A will
be attenuated according to Sim A-N volt scale every
2.70046 Seconds. The duration of the transient is
specified by the parameter Volt short time. The 2.70046
Seconds period was chosen so that the transient
condition gradually walks through the sine wave. In
order to simulate an open on phase A, set Sim A-N volt
scale to 1.0, Sim B-N volt scale to 1.0, and Sim C-N volt
scale to 0.5.
Sim B-N volt scale
Sim C-N volt scale
A-B volt fault scale
Sim B-N volt scale behaves identically to Sim A-N volt
scale except that it affects phase B instead of phase A.
Sim C-N volt scale behaves identically to Sim A-N volt
scale except that it affects phase C instead of phase A.
A-B volt fault scale simulates a line to line fault
between phases A and B. The default for A-B volt fault
scale is 0, providing no attenuation.

General Setup Functions
Keypad Overview
The Drive Diagnostic Interface (DDI; also known as the keypad) is mounted on the
door of an Innovation Series drive. The DDI provides a simple, easily accessible
means for a user to set, monitor, and maintain the drive locally.
The DDI provides both analog and digital representations of drive functions and
values. Its keypad is logically organized into two functional groups: navigation keys
and drive control keys. The Run and Stop keys are set to the side for easy access.
The operator can use the DDI to perform the following common tasks:
•
•
•
•
•
Monitor speed / current / voltage / power
Start/Stop the drive
Adjust a configuration parameter
Reset a fault condition
Commission the drive through a wizard
Each drive has its own DDI for local control.

Keypad Contrast Adjustment
Normally the LCD contrast of the Drive Diagnostic Interface (DDI) should be
adjusted at the DDI or keypad. The user can modify the Keypad contrast adj
parameter under the General Setup -> Keypad -> Keypad Functions menu.
A special keypad key sequence is also available to make this adjustment and is
especially useful when the contrast is too light or too dark to navigate the menus.
The sequence is to hold down the Menu key and press either the up (darker) or down
(lighter) arrow keys until the contrast is acceptable.
If your DDI firmware version is prior to V02.01.03C and the DDI contrast is too
light or too dark to navigate through the menus you will need to use Toolbox to find
the Keypad contrast adj parameter and make the adjustment.
Function configuration
Parameter
Description
Keypad contrast adj
Adjusts the contrast of the DDI LCD screen. Values are
from 0 to 63 where 63 is the darkest contrast. Setting

Analog Inputs/Outputs and Mapping
Analog Inputs
Two bipolar (±10 volts) analog inputs are available at the terminal board (ATB).
Jumpers on the BAIA board connect a burden resistor that allow these inputs to be
used for 4-20 ma references.
Analog in 1 offset and Analog in 2 offset provide a voltage offset adjustment. Analog
in 1 gain and Analog in 2 gain can be used to scale the inputs from volts to
appropriate application units. Analog in 1 filter and Analog in 2 filter provide first-
order signal softening at Analog input 1 and Analog input 2.
Loss of 4-20 ma signal can be configured by selecting a lower threshold Analog in 1
flt lev and Analog in 2 flt lev and then selecting the appropriate fault type, Analog in
1 flt mode and Analog in 2 flt mode.
Analog Outputs
Two bipolar (±10 volts) DAC outputs are available at the terminal board (ATB).
The signal to be output is selected by Analog out 1 select. This signal can be offset
by Analog out 1 offset using the same units as the signal to be output. The signal is
scaled for output by setting Analog out 1 scale to the value that will produce +10
volts. The second DAC is configured in a similar manner.
Meters
Four bipolar (±10 volts) meter drivers are available for use with the optional meter
assembly. This assembly is connected to the drive at connector J8 on the backplane.
The signal to be metered is selected by Analog meter 1 sel. This signal can be offset
by Meter 1 offset using the same units as the signal to be metered. The signal is
scaled for output by setting Analog meter 1 scale to the value which shall produce
+10 volts. Meter 1 mode is used to accommodate both 0 - +10 volt meters and -10 -
+10 volt meters. Analog meter 1 scale is unaffected by Meter 1 mode. The remaining
three meters are configured similarly.

Digital Inputs/Outputs and Mapping
Digital inputs and outputs provide an interface between the outside world and the
control. The ATB (terminal board) provides six general purpose digital inputs.
Three dry contact relays and one solid state relay driver are provided as outputs.
System and Local fault strings provide start and trip interlocks to the control.
Isolated digital inputs are listed with their associated terminal board points. A filter
debounces a noisy input signal. The filter should be set to zero in most instances,
since the hardware provides a level of debounce conditioning. The variables Digital
input 1 through Digital input 6 indicate the logical state of each digital input and are
used to interface to functions in the drive that require a Boolean signal.
Each relay output may be used by setting the parameters Relay 1 select through
Relay 3 select to the variables whose logical states are desired to drive the
corresponding relay. The associated terminal board points are shown for output
terminals of each relay. The variables Relay 1 state, Relay 2 state, and Relay 3 state
indicates whether the relay coils are energized.
Relay four is a solid-state relay driver that should be used for driving a 24 V dc, 10
mA relay. The relay driver output may be used by setting the parameter SS relay
driver sel to the variable whose logical state is desired to drive the relay. Solid state
relay indicates the status of the relay driver.
In addition to the four programmable outputs available on ATB, the drive provides 3
additional application outputs through the CTBC terminal board. The CTBC outputs
are not programmable but instead are mapped to some commonly used signals in the
drive. CTBC outputs are solid-state relay drivers that can be used for driving 24 V
dc, 10 mA relays. Signals available on CTBC are as follows:
CTBC Output
Pre-programmed function
D08 (pins 33 & 35)
D07 (pins 29 & 31)
D06 (pins 25 & 27)
Closed when No trip fault is True
Closed when Running is True
Closed when No faults active is True
A pilot relay controls a main contactor. Most applications do not require a contactor
(see MA contactor absent). This contactor is normally controlled through drive
sequencing, but it may be controlled alternately by MA close req sel. The contactor
cannot be energized if either the Local Fault String or the System Fault String are
open. If the contactor is closed and the Local Fault String or the System Fault String
open, the contactor will be de-energized.
Contactor status feedback is available (MA contactor closed). MA contactor fbk
determines if the drive sequencer requires MA contactor closed to be active in
response to a contactor close command.

Frame Phaselock Loop
The Frame Phaselock Loop function can synchronize the execution of the Innovation

periods are 1, 2, 4, and 8 milliseconds.
3-34 • Chapter 3 Paramters/Functions
Innovation Series Medium Voltage GP Type - G Drives GEH-6385
Function description
The product completely handles configuration of the Frame Phaselock Loop
function. Appropriate user selections of Network interface activate the function, and
user specification of LAN frame time sets the nominal period.
The Boolean variable Frame PLL OK status indicates the status of the Frame
Phaselock Loop. The asserted state indicates that the function has been activated and
that lock status has been validated. The unasserted state indicates that the function is
not activated or that lock status is not validated.
The FPLL Phase error signal reflects the phase error when valid phase information
has been extracted from the interface. A signal value of zero indicates either zero
phase error or invalid phase information. Scaling is such that one per-unit phase error
represents a full communication frame period.
The FPLL Freq Output signal is the frequency adjustment output of the function; the
authority of the function to modify away from nominal frequency is strictly limited.
When the function is not activated, the FPLL Freq Output signal is zero. When the
function is activated but no valid phase information is detected, then FPLL Freq
Output maintains its last valid calculated value.
When phaselock is achieved, Frame PLL OK status is asserted, FPLL Phase error is
at a zero-mean steady-state value, and FPLL Freq Output is at a non-zero, but very
small, steady-state value. When the Frame Phaselock Loop has been requested by
configuration but phaselock is not achieved, then Frame PLL not OK is shown.

Function description
Determining the integrity of the LAN interface involves several communication
layers, and may vary depending upon the specific communication options in use.
The Innovation Series Drive has two levels of validation available: LAN watchdog
and LAN heartbeat. Status information is conveyed to the user and/or application by
status signals and fault declarations.
GEH-6385 Reference and Troubleshooting, 2300 V Drives
Chapter 3 Paramters/Functions • 3-37
The LAN watchdog function describes the set of mechanisms the drive uses to
determine the status of the connection between DSPX and the module immediately
“above” the drive in the LAN hierarchy. For Dual-Port RAM interfaces, such as that
used for an embedded ACLA controller and for a direct LAN interface, the watchdog
takes the form of a handshake protocol. In this handshake protocol, the drive
determines the presence of a minimum level of intelligence on the host on the LAN
side of the shared memory. For ISBus interfaces, such as that used by a remote or
embedded ACLA controller, the watchdog reflects the reception of ISBus frame
synchronization codes. The watchdog function’s immediate authority is limited to
alarms and status variables, although the status information does play a functional
role in the interface management. Note that the watchdog does not offer information
about the LAN connection’s status which may be supported beyond the immediate
interface to DSPX. In fact, many device networks offer no means of determining
basic network health.
The LAN heartbeat function is visible to the user. The heartbeat function uses
published signal map channels, and is available for use by the application. It provides
a means to “loop back” a signal between the drive and any level in the LAN
hierarchy so a higher-level controller can validate the entire connection pathway,
including the drive itself. Locally, the drive can be configured to trigger a trip or
alarm if the heartbeat reference signal fails to transition within a configurable period
of time. The heartbeat offers the most robust validation options from a system
perspective, although it offers the least information about the detected problem’s
location.
The System ISBus error alarm occurs when an ISBus fault is detected in the DSPX
control. The variable Sys ISBus error reg contains the bit-coded value of the last
ISBus fault detected; each bit indicates a particular ISBus fault seen by the control.
The variable Sys ISBus error cnt increments upon fault detection. When initializing
the interface, the user should expect the alarm to signal intermittently.
The Frame PLL not OK alarm occurs when phase-lock between the DSPX control
and the System ISBus or (local ACL) is not assured. Detection of the fault is enabled
when the parameter Network interface is configured to select an interface for which
synchronized operation is supported. This alarm indicates that data coherency is
compromised. Status of the Frame Phaselock Loop function can be observed via the
signals Frame PLL OK status, FPLL Phase error, and FPLL Freq Output.
LAN Signal Map
The following information describes the primary signal interface between the
Innovation Series Drive and the product application layer interface. The application
layer may consist of an embedded ACL card, a direct LAN interface card, or an
application-level ISBus serial bus.
The LAN Signal Map is a fixed signal map that defines dedicated registered
communication channels for specific signals. It is defined in terms of paired
reference and feedback pages that are the same size physically. The internal data
organization of the reference and feedback pages may differ. The standard
Innovation Series signal map page consists of eight 32-bit elements.

Motor Control Functions
Motor Control Overview
The Innovation Induction motor control algorithm utilizes a Flux-Vector control
strategy. The motor control features include the following:
•
•
•
•
•
•
•
•
•
•
•
Motor torque, flux and thermal models
Online motor parameters adaptation
Voltage and current regulators
Voltage feedback offset correction
Power-Dip ride through control
Tach and Tachless mode operation
Tach loss detection
Current limit and Motor pull-out limit
Automatic field-weakening control
Torque Compensation
Cross-over voltage control
Motor Equivalent Circuit parameter information is required for the motor controller.
These parameters can be obtained by running the Motor Control Tuneup wizard
during commissioning of the drive. The motor parameters will change due to motor
temperature variations; because of this, on-line parameter adaptation, motor thermal
model and torque compensation schemes (shown in diagram, Motor Control
(Ovr_MCtrl) are incorporated in the motor control to enable accurate tracking of
torque, flux and calculated speed.
Motor electrical models are used to form feedforward models, feedback torque, flux
and speed calculations.
The induction motor controller can be used with or without tachometer. It can also be
configured to operate in tachometer control mode with automatic switch over to
Tachless control upon detection of a Tach-loss situation (comparison between model
calculated speed and actual speed feedback signal).
Field flux control can be manipulated by Flux ref ratio (inputs to motor control
shown in the diagram, Motor Control (Ovr_MCtrl). However, if the inverter output
voltage approaches its limit (Crossover Voltage) by increasing speed, an automatic
field-weakening control will take action to limit the output voltage (by reducing flux
command) to the Crossover Voltage level.
Current limits in the drive are affected by motor Pull-out torque capability, Power
Dip Protection control, and user current limit setting (as shown in diagram Motor
Control Interface (Core)). Motor pullout limit normally occurs when a large torque is
demanded in deep field-weakening operating region.

Flux Curve
The Flux Curve describes the relationship between the induction motor voltage and
current. Specifically, each point of the curve specifies the voltage that is measured at
the motor terminals for a particular excitation current, under no load conditions at the
nameplate frequency.
Function configuration
The Flux Curve consists of five voltage and current points. Two parameters are
associated with each point. The following table lists the parameters that configure the
Flux Curve.
Parameter
Description
Flux curve voltage 1
Flux curve voltage 2
Flux curve voltage 3
Flux curve voltage 4
Flux curve voltage 5
Flux curve amps 1
Flux curve amps 2
Flux curve amps 3
Flux curve amps 4
Flux curve amps 5
No load voltage for data point 1. RMS volts
No load voltage for data point 2. RMS volts
No load voltage for data point 3. RMS volts
No load voltage for data point 4. RMS volts
No load voltage for data point 5. RMS volts
No load current for data point 1. RMS amps
No load current for data point 2. RMS amps
No load current for data point 3. RMS amps
No load current for data point 4. RMS amps
No load current for data point 5. RMS amps
The parameters listed above specify the curve if they contain meaningful values. If
all the parameters are set to <No Value>, then the control uses the curve measured
during Motor Control Tuneup.
Function description
Often the motor data sheet contains four or five voltage and current measurements
that specify the Flux Curve. The voltage points are generally labeled "VNL" and the
current points "INL".
If five data points are available on the motor data sheet, they can be entered directly
into the configuration parameters. Flux curve voltage 1 and Flux curve amps 1
represent the smallest voltage and current, and Flux curve voltage 5 and Flux curve
amps 5 represent the largest voltage and current.
If fewer than five data points are available on the motor data sheet, the highest data
points should contain meaningful values and the lowest data points should be set to
<No Value>. To reset one of the parameters to <No Value>, highlight the value and
press the Delete key.
If the curve data is not available, all the configuration parameters should be set to
<No Value>, and the Flux Curve should be determined using the Motor Control
Tuneup.

Leakage Inductance Curve
The Leakage Inductance Curve describes the relationship between motor leakage
flux and torque current. The motor data sheet does not provide Leakage Inductance
Curve information. The characteristics of the curve can be obtained experimentally
or by running the Motor Control Tuneup.
Line Transfer
The Line Transfer function transfers a motor from the drive to the utility line and
captures a motor from the utility line to return control to the drive. In addition to the
parameters and variables documented here the Line Transfer Tuneup wizard is
provided to simplify and automate many of the tasks required to correctly
commission this function. To use this function you must have the necessary
contactors and operator interfaces as described in the "Innovation Series Line
Transfer Application Guide". The following figure summarizes the power one-line of
a basic line transfer application.

General operation
The following table specifies the general configuration parameters for this function.
Parameter
Description
Selects the source of the utility line reference. The use of the
internal line reference (ILR) is encouraged unless conditions exist
such that it is not possible to accurately predict the utility phase and
magnitude at the motor from the source voltage applied to the drive.
See the "Innovation Series Line Transfer Application Guide" for a
complete discussion of issues related to line reference selection.
Line reference
The following table specifies the general status variables for this function.
Variable
Description
Line xfer enabled
Indicates that the line transfer function is enabled.
Transfer MA
request
Indicates that the transfer/capture sequence has requested the
MA contactor to close.
