EFC5610 with diagnostic 9SC Surge current

Hello support,

We have an application using 160Kw EFC5610 to run and control a 200KW motor.

Intermittently we are getting diagnosis 9 SC surge current.

It is possible to operate the motor up to the full speed of 1790 rpm without error occurring.

So therefore we have discounted the suggested causes of failure for motor Short Circuit or Inverter module failure.

Parameter set attached

Any thoughts?

Thanks in advance
