POSSIBLE CAUSES
1: The ambient temperature is too high.
2: The air filter is blocked.
3: The fan is damaged.
4: The thermo-sensitive resistor of the IGBT
module is damaged.
5: The IGBT module of the inverter is dama-
ged.
1: The external fault signal connected at
DI.
2: The external fault signal connected at
virtual I/O.
1: The host computer is in an abnormal
state.
2: The communication cable is defective.
3: The communication extension card is
not configured correctly.
4: The communication parameters in
group bA are incorrectly configured.
1: The drive board and the power supply
are defective.
2: The contactor is faulty.
1: The HALL device is defective.
2: The transmission board is defective.
1: The motor parameters are not set accor-
ding to the nameplate.
2: Motor autotuning timeout has elapsed.
1: The encoder type is incorrect.
2: The encoder cable connection is
incorrect.
3: The encoder is damaged.
4: PG card is defective.

SOLUTIONS
1: The ambient temperature is too
high.
2: The air filter is blocked.
3: The fan is damaged.
4: The thermo-sensitive resistor of
the IGBT module is damaged.
5: The inverter IGBT module is
damaged.
1: Restart the operation.
2: Restart the operation.
1: Verify host computer wiring.
2: Verify the communication wiring.
3: Configure the communication
extension board correctly.
4: Configure the communication
parameters correctly.
1: Replace the defective unit board
or power supply board.
2: Replace the defective contactor.
1: Replace the defective HALL
device.
2: Replace the defective drive plate.
1: Set the motor parameters accor-
ding to the nameplate correctly.
2: Check the cable connecting the
frequency converter and the motor.
1: Set the encoder type correctly
according to the actual situation.
2: Eliminate external faults.
3: Replace damaged encoder.
4: Replace the defective PG card.
