1
1
Over-current
(hardware fault)
The drive has detected too high a current
(>4*I
H
) in the motor cable:
● sudden heavy load increase
● short circuit in motor cables
● unsuitable motor
Check loading.
Check motor.
Check cables and connections.
Make identification run.
Check ramp times.
2
Over-current
(software fault)
2
10
Over-voltage
(hardware fault)
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
Make deceleration time longer.
Activate overvoltage controller.
Check input voltage.
11
Over-voltage
(software fault)
3
20
Earth fault
(hardware fault)
Current measurement has detected that the sum
of motor phase current is not zero.
● insulation failure in cables or motor
Check motor cables and motor.
21
Earth fault
(software fault)
5
40
Charging switch
The charging switch is open, when the START
command has been given.
● faulty operation
● component failure
Reset the fault and restart.
Should the fault re-occur, contact the

60
Saturation
Various causes:
● Defective component
● Brake resistor short-circuit or
overload
Cannot be reset from keypad.
