327 DVDT Fltr Mismth
DVDT Filter Mismatch. Main control
board firmware has detected an invalid
combination of motor side inverter power
modules with and without dv/dt filters.
Either all power modules in the motor side
inverter must have dv/dt filters or none of
them must have the filters.
Power down. Then correct the
configuration.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically
reset: No. Emergency override
response: Cannot override this fault.

328 Inv AFE mode
Invalid AFE Mode. Main control board
firmware has detected power modules in
the line side converter with dv/dt filters.
None of the power modules in the line
side converter can have dv/dt filters.
Power down. Then correct the
configuration.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically
reset: No. Emergency override

330 No SysId Match
No System ID Match. The system does
not recognize the product type.
Power down and verify fiber-optic cable
connections.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically

331 Unknow Op Mode
Unknown Operational Mode. Unknown
Operating Mode was provided by a power
layer interface (PLI) circuit board.
Cycle power. If the fault persists,
replace power layer interface (PLI)
circuit boards one by one. See the
hardware service manual, publication
750-TG100 for PowerFlex 755T or
publication 750-TG101 for PowerFlex
755TS products, for the replacement
procedure.

334 Inv TAM Config
Invalid TAM Configuration. Main control
board firmware has detected a torque
accuracy module (TAM) connected to an
invalid channel on the fiber interface
circuit board.
Power down and examine the fiber-
optic connection on the fiber interface
circuit board to the torque accuracy
module (TAM). See the hardware
service manual, publication 750-TG100
for PowerFlex 755T or publication 750-
TG101 for PowerFlex 755TS products,
for information on the fiber transceiver
circuit board connections.

Fault
335 Inv Filtr Config
Invalid Filter Configuration. Main control
board firmware has detected a current
sense board (CSB) connected to an
invalid power layer interface (PLI) circuit
board. For paralleled converter power
modules, the CSB fiber-optic cable
connects to the lower numbered Ln
module. Example for L0 and L1, the CSB
connects to L0.
Power down and correct the fiber-optic
cable connections.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically
reset: No. Emergency override
response: Cannot override this fault.

344 SafetyInit Error
Safety Initialization Error. Safety system
failed to initialize due to unexpected
discrepancy in detected fiber peripherals.
Cycle power and verify fiber-optic cable
connections and peripherals. If this fault
persists, replace main control board
and/or peripherals. See the hardware
service manual, publication 750-TG100
for PowerFlex 755T or publication 750-
TG101 for PowerFlex 755TS products,
for the replacement procedure.

103 Device Timeout
Device Message Timeout. The main
control board has detected that one of the
power peripherals (power layer interface
board, current sense board, or precharge
board) has stopped transmitting
messages.
Check status indicators. Verify that all
power peripherals are powered. Power
down and then check the fiber-optic
communication connections. This fault
can be issued during some power
down sequences.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically
reset: No. Emergency override
response: Cannot override this fault.

200 Image Wtchdg Flt
Image Watchdog Fault. Communication
between the main control board and the
image buffer in one of the power
peripherals (power layer interface board,
torque accuracy module, or DC
precharge board) has stopped
transmitting for 10 milliseconds.
Power down and then check the fiber-
optic communication connections.
Coast (Motor Side Inverter). Stop
(Line Side Converter). Additional
Fault Action. Fault opens main circuit
breaker: No. Fault can automatically
reset: No. Emergency override
response: Cannot override this fault.

201 Const Inv Flt
Constants Message Invalid Fault. The
constants header information did not
match the content that is expected by the
power peripheral (power layer interface
board, current sense board, or precharge
board).
