Troubleshooting chart (continued)

Symptom

Possible cause

Action

Electric machine does not work
properly or the performance is
poor

Wrong electric machine parameters in
the inverter.

Check and correct the electric machine parameters from the inverter.

Demagnetization of magnets due to
overheating.

Measure the winding resistance, refer to manufacturer data. Replace the
electric machine if necessary.

Bearing fault.

Check the bearings, lubrication and conditions.

Insulation fault.

Measure the insulation resistance, refer to the manufacturer limits. See
Chapter 

Insulation resistance test

. Replace the electric machine if

necessary.

Anti-condensation heater failure

The heater element is faulty.

Measure the resistance of the heater element. See Chapter 

Anti-

condensation heater connections

 on page 51. If the heater is faulty,

contact Danfoss.

Temperature measurement failure The PT100 sensor is faulty.

Measure the resistance of the PT100 sensor, see Chapter 

Low

voltage connections

. If the sensor is faulty, read out the signal from

another sensor. Contact Danfoss. See Chapter 

 Emergency operation

.
