We purchased a Hayward ECO pump-motor-VFD approx 7 years ago and it's worked great since day 1..! Last week we had some rough weather and apparantly, this unit was hit by lightning. After checking, the PM motor and pump are good, VFD is toast. My question is, does anyone have PM electric motor information? Since this is a permanent magnet motor, it has to be controlled with a VFD bit there is information (normally found on nameplate) that has to be entered into VFD in order to operate. This information is not on nameplate and I'm curious if anyone can help me figure out back EMF voltage or a value close enough to allow autotune?
