Im tearing my hair out regarding this issue. We have a motor with an ATV61 on it. The drive keeps tripping out on IGBT desaturation. We have meggered the cable and motor and everything comes up clean. We have even changed the motor and still get this fault.
The ATV61 does have an IGBT diagnostics which checks the status op each IGBT. The test says all the IGBT's are ok with or without the motor connected.
Just hoping here someone has had the same problem somewhere.
Thanks for any advice
