3 to 6: Seek for maintenance.
Err10
Drive overload
1. The load is too heavy or the rotor is locked.
2. The drive is of too small power class.
1: Reduce the load, or check the motor, or check the
machine whether it is locking the rotor.
2: Select a drive of higher power class.
Err11
Motor overload
1. F9-01 is too small.
2. The load is too heavy or the rotor is locked.
3. The drive is of too small power class.
1: Set F9-01 correctly.
2: Reduce the load, or check the motor, or check the
machine whether it is locking the rotor.
3: Select a drive of larger power class.
Err12
Power input
phase loss
1. The three-phase power supply is abnormal.
2. The drive board is faulty.
3. The lightening protection board is faulty.
4. The control board is faulty.
1: Check the power supply.
2 to 4: Seek for maintenance.
Err13

fault
1. Motor parameters are wrong.
2. Motor tuning overtime.
1. Check motor parameters F1-00 to F1-05.
2. Check the wiring between drive and motor.
Err21
EEPROM
read-write fault
The EEPROM chip is damaged.
Replace the main control board.
Err23
Short circuit to
ground
The motor is short-circuited to ground.
Replace the cables or motor.
Err26
