Fault
Name
Display Possible Causes Solutions
AC drive
overload
Err10
1: The load is too heavy or
lockedrotor occurs on the motor.
2: The AC drive model is of too
small power class.
1: Reduce the load and
check the motor and
mechanical condition.
2: Select an AC drive of
higher power class.
Motor
overload
Err11
1: P9-01 is set improperly.
2: The load is too heavy or
lockedrotor occurs on the motor.
3: The AC drive model is of too
small power class.
1: Set P9-01 correctly.
2: Reduce the load and
check the motor and the
mechanical condition.
3: Select an AC drive of
higher power class.
Power
input
phase loss
Err12
1: The three-phase power input is
abnormal.
2: The drive board is faulty.
3: The lightening board is faulty.
4: The main control board is faulty.
1: Eliminate external faults.
2: Contact technical
support.
Power
output
phase loss
Err13
1: The cable connecting the AC
drive and the motor is faulty.
2: The AC drive's three-phase
outputs are unbalanced when the
motor is running.
3: The drive board is faulty.
4: The IGBT is faulty.
1: Eliminate external faults.
2: Check whether the
motor three-phase winding
is normal.
3: Contact technical
support.
IGBT
overheat
Err14
1: The ambient temperature is too
high.
2: The air 󽗉lter is blocked.
3: The fan is damaged.
4: The thermally sensitive resistor
of the IGBT is damaged.
5: The AC drive IGBT is damaged.
1: Lower the ambient
temperature.
2: Clean the air 󽗉lter.
3: Replace the damaged fan.
4: Replace the damaged
thermally sensitive resistor.
5: Replace the AC drive IGBT.
External
equipment
fault
Err15
1: External fault signal is input via DI.
2: External fault signal is input via
virtual I/O.
Reset the operation.
