What to Do
Check inverter fan.
Check ambient temperature.
Check liquid cooling system.
Reduce load or increase ramp time.
Increase parameter 20.03
Check Fault Function parameters.
Check motor load and drive ratings.
Check Fault Function parameters.
Wait until drive indicates that motor
identification is completed.
Check motor ratings, load and cooling.
Check start-up data.
Check Fault Function parameters.
Check value of alarm limit.
Check that actual number of sensors
corresponds to value set by parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
