Control board.
parameters were not programmed.
Incorrect I/O board identified.
Loss of communication to I/O board.
Board failure.
High current was detected in an IGBT.
High current was detected in an IGBT.
ware reported unexpected fault.
Inverter gate kill contact is open.
High current was detected in an IGBT.
Rectifier overcurrent.
Temperature switch in reactor opened.
Rectifier section of power structure hard-
ware reported unexpected fault.
Excessive ground current measured.
measured.
Short-term current rating of rectifier
exceeded.
Long-term current rating of rectifier
exceeded.
Input power loss timed out.
Input line voltage is too high.
The bus voltage is too low.
The bus voltage is too high.
ACTION
Load compatible version files into drive.
a. Press reset.
b. Reprogram parameters.
Restore I/O board to original configuration, or,
if new configuration is desired, reset fault.
Cycle power.
a. Cycle power.
b. If fault repeats, replace I/O board.
a. Check for loose connection in IGBT wire
harness.
b. Check IGBTs.
c. Check precharge resistors and fuses.
d. Check precharge contactor.
a. Verify proper motor data is entered.
b. Reduce current limit.
Check wiring harness.
Close gate kill contact.
a. Check for loose connection in IGBT wire
harness.
b. Check IGBTs.
a. Verify proper motor data is entered.
b. Reduce current limit.
Check for proper temperature and fan
operation.
Check wiring harness.
Check for grounded input wiring.
Check for proper temperature and flow rate of
coolant.
Check for proper temperature and flow rate of
coolant.
Low input voltage can result in increased cur-
rent load. Provide proper input voltage to the
drive.
Low input voltage can result in increased cur-
rent load. Provide proper input voltage to the
drive.
a. Verify input power and connections.
b. Check Line Sync board.
c. Check AC Line I/O board.
Reduce input voltage to meet specification of
480 ±10%.
Verify proper input voltage.
Monitor the AC line for high line voltage or
transient conditions. Bus overvoltage can also
be caused by motor regeneration. Extend the
decel time or install dynamic brake option.
