2: The cable connection of the
encoder is incorrect.
3: The encoder is damaged.

Damaged EEPROM Chip
1: Overvoltage;
2: Overcurrent.
Ground fault of the motor
The user-defined fault 1 signal is
input via Terminal X.
The user-defined fault 2 signal is
input via Terminal X.
Accumulated power-on time
(F8.13) reaches the set value
(F4.16).
Operation current of inverter is
smaller than F9.64.
The PID feedback is lower than
the setting of FA.26.
1: Excessive load or motor
stalling;
2: The model of inverter is too
small.
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
activated.
3: F9-69 and F9-70 are set
incorrectly.
1: The encoder parameters are set
incorrectly.
2: The motor auto-tuning is not
activated.
3: F9.67 and F9.68 are set
incorrectly

1: Set the encoder type correctly
based on the actual situation.
2: Eliminate external faults.
3: Replace the damaged encoder.
4: Replace the faulty PG card.
Replace the main control board.
1: Deal it as overvoltage error;
2: Deal it as overcurrent error.
Change electric cables or motors.
Reset the operation
Reset the operation
Clear the records using the initiation
of parameters.
Confirm the removal of load or if
parameters setting of F9.64 and
F9.65 matches real situation.
Check the PID feedback signal or
set FA.26 to a proper value.
1: Reduce load and inspect the
motor and mechanical conditions;
2: Use the inverter that has a higher
power level.
1:Set the encoder parameters
properly.
2: Perform the motor auto-tuning.
3: Set F9.69 and F9.70 correctly
based on the actual situation.
1:Set the encoder parameters
properly.
2: Perform the motor auto tuning.
3: Set F9.67 and F9.68 correctly
based on the actual situation.
