Wow Mike with those qualifications it should be a breeze for you to fault find a VFD ! and it surprises me that one with such qualifications would ask for help with an electrical problem .
Oh well noted for future reference .
I was just doing my best with the limited information in your first post .
My bad I should have wrote low
Reducing the accel time to 4s will increase current draw .
I would have used a Megger and do to test for electric motor insulation faults . DMM,s can lie as using the DMMs 9v internal battery is not a real test of a motor's insulation , but hey what do I know you're the expert

Quote:#3 , have you reduced the acceleration time , if sethighlow this will cause a high inrush current .
