Description
The time limit for the short term current in-
jection has been exceeded.
An excessive common mode current has
been detected in the LCL-filter.
A resonance on the DC link with excessive
RMS current values has been detected.
The rectifier is thermally overloaded. Mission
profile is too demanding.
An overcurrent on the main DC-link capaci-
tors has been detected.
The drive has exceeded the allowed time in
current limit.
Thermal overload is detected in the inverter
of the drive. Reduce the output load.
The output current of the drive has exceeded
its normal range at low speed. Shock load or
too fast acceleration with high-inertia loads
can cause this fault. Check that the motor
size matches the drive and the motor data
is correct. Check that the motor shaft can be
turned.
The output current of the drive has exceeded
its normal range. Shock load or too fast ac-
celeration with high-inertia loads can cause
this fault. Check that the motor size matches
the drive and the motor data is correct. Check
that the motor shaft can be turned.
The output current of the drive has exceeded
the current limit multiple times. Check that
the motor size matches the drive and the mo-
tor data is correct. Check that the motor shaft
can be turned.
A Smart Derating fault is detected. The load is
too demanding for the current derating level.
Lower the switching frequency if possible.
