Cause
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.
•
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.
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.
•
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.
Power unit has detected a ground fault.
Ground fault in the power cables.
•
Winding fault or ground fault at the
•
motor.
Remedy
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.
Reduce the continuous load.
•
Adapt the load duty cycle.
•
Check the motor and power unit rated cur-
•
rents.
Check the main circuit fuses.
•
Check whether a single-phase load is dis-
•
torting the line voltages.
Check the motor feeder cables.
•
Check the motor feeder cables.
•
Check the speed controller settings.
•
Check the power cable connections.
•
Check the motor.
