Any abnormity occurs during operation, the driver will lock PWM output immediately and enter
protection status. Meanwhile, the keypad will display function codes indicating the current fault,
and the ALM indicator light will be on.
Follow the method described in Table 6-1 to check the fault cause and conduct according actions.
If the problem remains, contact us directly.

code
Fault
descriptions
Possible reasons Actions
E-01
Over-current
in Acc process
Too short Acc time (including
tuning process)
Prolong the Acc time
Restart the rotating motor Start after setting as DC brake, or
rotational speed tracking start
Drive power is too small Select a higher power drive
V/F curve is not suitable
Adjust V/F curve or torque boost
E-02
Over-current
in Dec process
Too short Dec time (including
tuning process)
Prolong the Dec time
Too low driver's power Select the drive with large capacity
the load inertia is too high Connect suitable braking resistor or
braking unit
E-03
Over-current
in constant
speed
operation
Low network voltage Check the power supply
Sudden change or abnormal
of load
Check the load or reduce the change of
the load
Too low driver's power Select the driver with larger capacity
E-04
Over voltage
in Acc process
Abnormal supply voltage
(including tuning process) Check the power supply
The driver is restarted with a
rotating motor
Start after setting as DC braking, or
rotational speed tracking start
Special potential energy load Connect suitable braking resistor or
braking unit
E-05
Over voltage
in Dec process
Too short Dec time (including
tuning process)
Prolong the Dec time
The load inertia is too high Connect suitable braking resistor or
braking unit
Abnormal of supply voltage Check the power supply
