Faults and Alarms
Number / Fault Cause
F008 The lower limit value of 76 % of the DC link
voltage (P071 Line Volts), or of 61 % when
DC link undervoltage kinetic buffering has been enabled, has been
fallen short of.
Undervoltage in the DC link in 'normal'
operation (i.e. no SIMULATION).
Undervoltage in the DC link with active kinetic
buffering and speed less than 10 % of the
rated motor speed.
It was a 'brief power failure' which was not
detected until system recovery (auto restart
flag).
F010 Due to excessive DC link voltage, shutdown
has taken place:
DC link overvoltage Line voltage
380 V - 480 V
Note:
Only at U800 = 1 and f(Pulse) > f(derating)
Lower threshold value than F006 !
F011 Overcurrent shutdown has occurred.
The shutdown threshold has been exceeded.
Overcurrent
F012 During excitation of the induction motor, the
current did not rise above 12.5 % of the
I too low setpoint magnetizing current for no-load
operation.
F014 During excitation of the motor, the current
component is less than 25 % of the motor no-
I too low load current.
Note:
Only for U800 = 1
Irrespective of the type of control

Operating Instructions
Counter-measure
Check
- Input DC voltage
- DC link
Check the supply voltage
Check the braking resistor
Converter operates regeneratively without a
feedback possibility. Braking unit must be set
to the lower response threshold (673 V)
- Check the converter output for short-circuit or
earth fault
- Check the load for an overload condition
- Check whether motor and converter are
correctly matched
- Check whether the dynamic requirements
are too high
Only for closed loop n/f/T control (P100 = 3, 4
or 5)
If no motor is connected, go into the simulation
mode P372.
Check current detection, check power section.
Check the output contactor
Check the motor cable
