Possible Cause
The drive has detected too high a current (>4*I
the motor cable:
● sudden heavy load increase
● short circuit in motor cables
● unsuitable motor
The DC-link voltage has exceeded the limits
defined.
● too short a deceleration time
● high over-voltage spikes in supply
● Start/Stop sequence too fast
Current measurement has detected that the sum
of motor phase current is not zero.
● insulation failure in cables or motor
The charging switch is open, when the START
command has been given.
● faulty operation
● component failure
Various causes:
● Defective component
● Brake resistor short-circuit or
overload

) in Check loading.
H
Check motor.
Check cables and connections.
Make identification run.
Check ramp times.
Make deceleration time longer.
Activate overvoltage controller.
Check input voltage.
Check motor cables and motor.
Reset the fault and restart.
Should the fault re-occur, contact the
distributor near to you.
Cannot be reset from keypad.
Switch off power.
DO NOT RECONNECT POWER!
Contact the factory.
If this fault appears simultaneously with F1,
check motor cables and motor.
