Hi We are using WCIII Robicon VFD for extruder application. Recently after long shutdown with Siemens support did Hoses change. After this we did OLTM and found output voltage fluctuations from 40% demand to 80% demand by 200-300Volts variation. SCB, output attenuators along with transorbs and diodes, modulator board, System interface board replaced but no improvement seen. There are no any alarms nor debug tool faults indicating cell issues. Is this ok, to proceed for motor solo run OR Regards, N Vijay ------------------------------------------------------------------------------------------ |

You've been a member of this for almost 10 years and you should know it: No multiple posts for the same problem. You have also opened your own topic for your problem: OLTM variations
