"A fatal alarm occured while the MCS inverter unit and MCS software are executing their processing"
'#13'-> IPM protective function activated
Not long ago we replaced the MIP22 spindle drive with a refurbished unit. Since then this alarm would appear every now and then but now it is frequent. I have my suspicions but would like to get some fresh perspective.
Have you checked the cable connections at the drive and the inverter? As I understand it that is the most common cause for that paticular error.
