Fault code

What does the FREQROL-F400's fault code (E.0uT) mean?
Category : 


Regenerative overvoltage protection (E.OVT).
This error occurs when the regenerative power returns from the motor to the inverter (for example, during deceleration) and the DC bus voltage inside the inverter exceeds the protection level.
As a countermeasure, lengthen the deceleration time (Pr.7) or use the brake unit (BU or FR-BU).
