WHAT TO DO
Check motor current settings and group 77
settings.
Wait until drive has finished task.
See Master drive for more detailed description
of fault of limit.
Reduce load or increase ramp time.

Increase parameter
CURRENT value.
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 with parameter.
Let motor cool down. Ensure proper motor
cooling: Check cooling fan, clean cooling
surfaces, etc.
