F004, A0503, r0200=0

JHoltbean Posts: 3 Rating: (0)	I have a MicroMaster drive that recently had an IGBT replaced and now it comes up with F004 and A0503 when it boots up. I've checked the actual DC link voltage with a multimeter and it is around 670 VDC. I noticed that r0200 is 0 and from what I've seen on other posts is that means there is a hardware malfunction. I'm wondering if someone can point me in the right direction to fix this problem?
