Cause : Excessive intermediate circuit DC voltage.
Check that overvoltage controller is on, parameter 47.01 Overvolt ctrl.
Check that the supply (input power) voltage matches the drive nominal input voltage.
Check mains for static or transient overvoltage.
Check brake chopper and resistor (if used).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit frequency converter with brake chopper and brake resistor.
