Fault
Cause
Remedy
F30004: Drive heat sink
overtemperature
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The temperature of the power unit heat
sink has exceeded the permissible limit
value.
• Insufficient cooling, fan failure.
• Overload.
• Surrounding air temperature too high.
•
Pulse frequency too high.
• Check whether the fan is running.
• Check the fan elements.
• Check whether the surrounding air temper-
ature is in the permissible range.
• Check the motor load.
• Reduce the pulse frequency if this is higher
than the rated pulse frequency.
F30005: Power unit: Over-
load 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 cur-
rents.
F30011: Line phase failure
in main circuit
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
At the power unit, the DC link voltage
ripple 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 dis-
torting 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.
