Cause : The load on the drive has fallen below the low load detection level comes when the low load detector is active, the low load condition is detected when the Percentage Load (Pr 04.020) falls below the threshold defined by the Low Load Detection Level (Pr 04.027).
- Enable Trip On Low Load (Pr 04.029) defines the action taken when low load is detected.
- If Enable Trip On Low Load (Pr 04.029) = 0, a Low Load warning is displayed and Low Load Detected Alarm (Pr 10.062) = 1.
- If Enable Trip On Low Load (Pr 04.029) = 1 no warning is given, but a Low Load trip is initiated.
- Check the load on the motor has not changed
