Overvoltage at
constant speed
Err07
1: The input voltage is too high.
2: An external force drives the motor during
deceleration.
1: Adjust the voltage to normal
range.
2: Cancel the external force or
install the braking resistor.
Control power
supply fault
Err08
The input voltage is not within the allowable
range.
Adjust the input voltage to the
allowable range.
Under voltage
Err09
1: Instantaneous power failure occurs on
the input power supply.
2: The AC drive's input voltage is not within
the allowable range.
3: The bus voltage is abnormal.
4: The rectifier bridge and buffer resistor
are faulty.
5: The drive board is faulty.
6: The main control board is faulty
1: Reset the fault.
2: Adjust the voltage to normal
range.
3: Contact the agent or HNC
Electric.
AC drive overload Err10
1: The load is too heavy or locked-rotor
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 locked-rotor
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 the agent or HNC
Electric.
