I've deliberated on a suitable replacement drive for the original, failed Yaskawa drive. Yaskawa did not inspire any confidence in their recommendation when I contacted them. At the recommendation of a few that have done more of this than me, I ordered the 10HP HY import VFD. I received it today. I currently have accel/decel both set at 8 seconds. Single phase 240v supply sees about 20a peak on that acceleration time. Running current, spinning the spindle only, is 6a in, around 5a out.
I don’t expect this drive to perform like a drive that would cost 10x the $300 I paid for it. It is nice to see the spindle move. For the money, I can see why guys like these drives.
I wonder what the old drive’s life was like..
