Fault
Cause
Remedy
F30004: Drive heat sink over-
temperature
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The temperature of the power unit heat
sink has exceeded the permissible limit
value.
•
Insufficient cooling, fan failure.
•
Overload.
•
Surrounding temperature too high.
•
Pulse frequency too high.
•
Check whether the fan is running.
•
Check the fan elements.
•
Check whether the surrounding tempera-
ture is in the permissible range.
•
Check the motor load.
•
Reduce the pulse frequency if this is high-
er than the rated pulse frequency.
F30005: Power unit: Overload
I
2
t
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The power unit was overloaded.
•
The permissible rated power unit cur-
rent was exceeded for an inadmissibly
long time.
•
The permissible load duty cycle was
not maintained.
•
Reduce the continuous load.
•
Adapt the load duty cycle.
•
Check the motor and power unit rated
currents.
F30011: Line phase failure in
main circuit
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
At the power unit, the DC link voltage rip-
ple has exceeded the permissible limit
value.
Possible causes:
•
A line phase has failed.
•
The 3 line phases are inadmissibly
unsymmetrical.
•
The fuse of a phase of a main circuit
has ruptured.
•
A motor phase has failed.
•
Check the main circuit fuses.
•
Check whether a single-phase load is
distorting the line voltages.
•
Check the motor feeder cables.
F30015: Phase failure motor
cable
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
A phase failure in the motor feeder cable
was detected.
The signal can also be output in the follow-
ing case:
The motor is correctly connected, however
the closed-speed control is instable and
therefore an oscillating torque is generat-
ed.
•
Check the motor feeder cables.
•
Check the speed controller settings.
F30021: Ground fault
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
Power unit has detected a ground fault.
•
Ground fault in the power cables.
•
Winding fault or ground fault at the
motor.
•
Check the power cable connections.
•
Check the motor.
