Cause
The pole position identification routine was
unsuccessful.
The power unit has detected an
overcurrent condition.
•
Closed-loop control is incorrectly
parameterized.
•
Motor has a short-circuit or fault to
ground (frame).
•
Power cables are not correctly
connected.
•
Power cables exceed the maximum
permissible length.
•
Power unit defective.
•
Line phase interrupted.
The power unit has detected overvoltage in
the DC link.
•
Motor regenerates too much energy.
•
Device connection voltage too high.
•
Line phase interrupted.
The power unit has detected an
undervoltage condition in the DC link.
•
Line supply failure
•
Line supply voltage below the
permissible value.
•
Line supply infeed failed or interrupted.
•
Line phase interrupted.
The temperature of the power unit heat
sink has exceeded the permissible limit
value.
•
Insufficient cooling, fan failure.
•
Overload.
• Ambient temperature too high.
•
Pulse frequency too high.
The power unit was overloaded.
•
The permissible rated power unit
current was exceeded for an
inadmissibly long time.
•
The permissible load duty cycle was
not maintained.
Remedy
Contact the Hotline.
•
Check the motor data - if required, carry out
commissioning.
•
Check the motor circuit configuration (star-
delta)
•
Check the power cable connections.
•
Check the power cables for short-circuit or
ground fault.
•
Check the length of the power cables.
•
Replace power unit.
•
Check the line supply phases.
• Check the external braking resistor
connection.
• Increase the ramp-down time
•
Activate the DC link voltage controller
•
Use a braking resistor
•
Increase the current limit of the infeed or
use a larger module
•
Check the device supply voltage
•
Check the line supply phases.
•
Check the line supply voltage
•
Check the line supply infeed and observe
the fault messages relating to it (if there are
any)
•
Check the line supply phases.
•
Check the line supply voltage setting.
•
Check whether the fan is running.
•
Check the fan elements.
•
Check whether the ambient temperature 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
currents.
