F30005
Power unit: Overload I2t
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power unit was overloaded (r0036 = 100 %).
- the permissible rated power unit current was exceeded for an inadmissibly long time.
- the permissible load duty cycle was not maintained.
Fault value (r0949, interpret decimal):
I2t [100 % = 16384].
Remedy:
- reduce the continuous load.
- adapt the load duty cycle.
- check the motor and power unit rated currents.
- Reduce the current limit p0640.
- During operation with V/f characteristic: reduce p1341 of the current limiting controller.

F30006
Power unit: Thyristor Control Board
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The Thyristor Control Board (TCB) of the Basic Line Module signals a fault.
- there is no line supply voltage.
- the line contactor is not closed.
- the line supply voltage is too low.
- line supply frequency outside the permissible range (45 ... 66 Hz).
- there is a DC link short-circuit.
- there is a DC link short-circuit (during the pre-charging phase).
- voltage supply for the Thyristor Control Board outside the nominal range (5 ... 18 V) and line voltage >30 V.
- there is an internal fault in the Thyristor Control Board.
Remedy:
The faults must be saved in the Thyristor Control Board and must be acknowledged. To do this, the supply voltage
of the Thyristor Control Board must be switched out for at least 10 s!
- check the line supply voltage
- check or energize the line contactor.
- check the monitoring time and, if required, increase (p0857).
- if required, observe additional power unit messages/signals.
- check the DC link regarding short-circuit or ground fault.
- evaluate diagnostic LEDs for the Thyristor Control Board.
F30011
Power unit: Line phase failure in main circuit
Reaction:
OFF2 (OFF1)
Acknowledge:
IMMEDIATELY
Cause:
A line phase failure was detected at the power unit.
- the fuse of a phase of a main circuit has ruptured.
- the DC link voltage ripple has exceeded the permissible limit value.
Note:
The cause may also be a phase failure in the motor feeder cable.
Remedy:
- check the main circuit fuses.
- check the motor feeder cables.
