The SOF [Motor Overspeed] fault condition appears when an overspeed is present on the drive. Unstable or too large and overhauling load.
Resolution:
The threshold is 110% of the TFR parameter and during 250 ms in open or closed loop mode.
Check the motor parameters and the speed feedback loop if it applies.
Ensure that CLI [Current Limitation] is set higher than nCr [Nominal Motor Rated Current]
Adding a braking resistor.
Check the size of the motor, drive and or load.
