Fault
Cause
Remedy
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.
F30027: Precharging DC link
time monitoring
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
•
The power unit DC link was not able to
be pre-charged within the expected
time.
There is no line supply voltage con-
nected.
• The line contactor/line side switch has
not been closed.
• The line supply voltage is too low.
• The pre-charging resistors are over-
heated as there were too many pre-
charging operations per time unit
• The pre-charging resistors are over-
heated as the DC link capacitance is
too high.
• The pre-charging resistors are over-
heated.
• The pre-charging resistors are over-
heated as the line contactor was
closed during the DC link fast dis-
charge through the Braking Module.
• The DC link has either a ground fault
or a short-circuit.
• The pre-charging circuit is possibly
defective.
Check the line supply voltage at the input ter-
minals.
F30036: Internal over-
temperature
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The temperature inside the drive has ex-
ceeded the permissible temperature limit.
• Insufficient cooling, fan failure.
• Overload.
• Surrounding air temperature too high.
•
Check whether the fan is running.
• Check the fan elements.
• Check whether the surrounding air temper-
ature is in the permissible range.
Notice:
This fault can only be acknowledged once the
permissible temperature limit minus 5 K has
been fallen below.
