YASKAWA v1000 plc

2 posts in this topic

Over the past couple months we have had 5 Yaskawa v1000 CIMR-VU2A0002FAA VFD go bad. While this is only a small fraction of how many we have its still alot to go bad when the line is only 8 years old. 

They got a ol1 fault. Investigate, find no issues with the motor and wiring. Replace the vfd and the problem goes away for good. 

Is something causing these vfd to go bad or did Yaskawa simply produce bad vfd 8 years ago. 

Only experience with VFD is Mitsubishi VFD and they seem to last forever. 

Background information. 

208 v 3 phase (Input and Output)

Used to power 2 foot section of conveyor moving engine heads. 

Motor= Baldor IDGMP2503

I would check the physical motor install, verify bearings are good, check runout / alignment, things like that would cause the drive to be working too hard.

Also recommend plugging into the drive and using the software to monitor the drives performance. it might point you in the right direction.
