Cause : DC overvoltage comes when the intermediate circuit voltage exceeds the limit, the adjustable frequency drive trips after a time.
- Connect a brake resistor.
- Extend the ramp time.
- Change the ramp type.
- Activate the functions in 2-10 Brake Function.
- Increase 14-26 Trip Delay at Inverter Fault.
- If the alarm/warning occurs during a power sag, use kinetic backup (14-10 Line Failure).
