Just a heads-up.........
1) If the motor is 3 phase, it'll work just fine. Slamming a 3Ø motor in the other direction while it is running is called 'plugging'. Perfectly fine for most motors.
2) If it's a basic standard single phase motor, swapping 5 & 8 (the start winding) while it's running won't make it reverse. The motor needs to be going slow enough (or stopped) that the start winding is engaged in order to make it change direction. Instant-reverse single phase motors are available but they need to be built this way from the factory.
Thanks
Yes it is 3 phase.
It has a 5 position hand/drum switch on it. LF, HF OFF, LR, HR.
It also had 2 micro switches on the quill and a busted up plastic enclosure on the front to auto reverse.
That added a lot of wires and junk hanging all over it - which I never liked the looks of.
I had him remove the micro switches and give me one foot switch. Also move the main and reversing contacters into a single enclosure which is now up top and facing the back and not in your face like it was.
I mounted the enclosure so it will swivel to the side if you need to work in it.
He'll be back to finish on Friday.
