Thanks for the detailed response!! Awesome!

I know I 've had the "oC" fault for overcurrent. I believe I have also gotten "oH" and possibly another one. Not sure if the drive is just being overworked or if I have other issues.

I believe it is a J1000 Yaskawa drive and the motor is 2/3 HP.

Yaskawa Drive Reviews

I have a Yaskawa drive that has given me various faults at various times. It is a few years old and it seems like it should have lasted longer so I am considering replacing it with another brand.

Any Yaskawa drive reviews, complaints, compliments, etc for other Yaskawa drive users?

Looking for some help fault troubleshooting Yaskawa AC drives. I have had a few faults on a tested and proven application. Not sure if these drives are junk, or if I have need to replace and start over. This particular Yaskawa AC Drive is a J1000.

Any thoughts on Yaskawa AC Drives or advice on troubleshooting these units?
