Anybody else experienced intermittent OC (Overcurrent stable conditions) fault on the Rockwell VSD attached to Mquay centrif. Also shows LU (Low dc bus voltage) at the same time. Not been on site while the fault occurs. Mains voltage is fine, it has been monitored, vfd settings have been verified.
Any assistance would be greatly appreciated.
