Good day everyone
I am in the process of wiring a 2.2kw spindle to a Haunyang VFD type 2. Checking continuity to determine which of the 3 inputs should receive the ground wire shows that none of them are grounded to the spindle case. I opened up the top to see if any of the wires were loose and I cant tell which of them is the ground. Shouldn't the case be grounded? I would appreciate any input.
