Make sure that no real overcurrent or block on the motor 2. Swap power module 3. If fault disappeared repair damaged power module Good luck Rejjal Attachment Power module board .jpg (344 Downloads)

Regarding repairs, I have received a recommendation from the Product Management: Product Management We would like to point out that for such a repair, which is carried out independently, is at your own risk. It is advised to contact trained personnel, as always indicated in the manuals, e.g. in the following FAQ in chapter 11 "Spare Parts and Service": Further information regarding SIMODRIVE can be found here: https://support.industry.siemens.com/cs/products?dtp=Manual&mfn=ps&pnid=13259&lc=en-WW Best regards, Jen_Moderator
