F30005
Power module: Overload I2T
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power module was overloaded (r0036 = 100 %).
- the permissible rated power module current was exceeded for an inadmissibly long time.
- the permissible load duty cycle was not maintained.
Fault value (r0949, decimal):
I2t [100 % = 16384].
Remedy:
- reduce the continuous load.
- adapt the load duty cycle.
- check the motor and power module rated currents.

F30006
Power module: Thyristor control board
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The thyristor control board of the basic line module signals a fault.
- there is not 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).
- power supply thyristor control board outside the nominal range (5 ... 18 V) and supply voltage >30 V.
- there is an internal fault in the thyristor control board.
Remedy:
The faults are saved in the TCB and are acknowledged by switching-out the TCB supply voltage 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 module messages/signals.
- check the DC link regarding short-circuit or ground fault.
- observe the LED fault display of the thyristor control board.
A30010 (F)
Power module: Sign-of-life, cyclic data
Reaction:
NONE
Acknowledge:
NONE
Cause:
A DRIVE-CLiQ communications error has occurred between the control unit and the power module involved.
The cyclic setpoint telegrams of the control unit were not received on time by the power module for at least one clock
cycle.
Remedy:
- check the electrical cabinet design and cable routing for EMC compliance
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowledge
upon F:
IMMEDIATELY (power on)
F30011
Power module: Line phase failure in main circuit
Reaction:
OFF2 (OFF1)
Acknowledge:
IMMEDIATELY
Cause:
A line phase failure was detected at the power module.
- the fuse of a phase of a main circuit has ruptured.
- the DC link voltage ripple has exceeded the permissible limit value.
Remedy:
Check the fuses in the main circuit.
F30012
Power module: Temperature sensor heatsink wire breakage
Reaction:
OFF1 (OFF2)
Acknowledge:
IMMEDIATELY
