Possible causes
1.the motor parameters was
not set according to the
nameplate
2.the identification process of
parameter is timeout
1.the encoder is damaged
2.PG card is abnormal
3.the encoder model does not
match
4.the encoder connection has
error
EEPROM chip is damaged
1.overvoltage
2.overcurrent
Motor short to ground
Cumulative running time
arrival fault
Input custom fault 1 signal
through the multi-function
terminal DI
Input custom fault 2 signal
through the multi-function
terminal DI
Total power-on time reaches
the set value
The inverter running current is
less than F8.31
PID feedback is less than the
set value of E2.11
1.whether the load is too large 1.reduce the load and

Chapter 7 Troubleshooting
Solutions
1.correctly set motor
parameter according to the
nameplate
2.check the lead wire from
the inverter to the motor
1.replace the encoder
2.replace the PG card
3.correctly set the encoder
model according to the
Actual conditions
4.eliminate the line fault
Replace the main control
panel
1.eliminate overvoltage
fault
2.eliminate overcurrent
fault
Replace the cable or motor
