1
Overcurrent
(hardware fault)
AC drive has detected too high a cur-
rent (>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
Overcurrent
(software fault)

10
Overvoltage
(hardware fault)
The DC-link voltage has exceeded the
limits defined.
• too short a deceleration time
• brake chopper is disabled
• high overvoltage spikes in supply
• Start/Stop sequence too fast
Make deceleration time longer.
Use brake chopper or brake
resistor (available as options).
Activate overvoltage controller.
Check input voltage.
11
Overvoltage (soft-
ware fault)
3
20
Earth fault (hard-
ware 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 (soft-
ware fault)

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, con-
tact the distributor near to you.

Various causes:
• defective component
• brake resistor short-circuit or
overload

DO NOT RE-CONNECT POWER!
Contact factory.
If this fault appears simultane-
