I'm trying to wrap my head around some things before I finish the wiring of the VFD to a BP clone.
Breaking it down to the most simplistic explanation it is my understanding that source logic (jumper from L to PLC) is basically making terminals 1-7 ground side switching and the opposite for sink logic (jumper wire PLC to P24) correct?
The jog switch explaination is a bit vague for me. Can someone explain this better than the manual. First do I need an actual on/off switch or can it be a momentary switch for the jog button? I am a bit confused by the procedure for using it. As I understand it I need to turn the jog on first then the fw or rev switch. How do I repeat this ? I will be using a drum switch with center off for fw/rev. The switch is actually a 2 pole but I assume I should be able to use it in place of a single pole with the center off.
I wish to see if this example I am about to give is correct as well. If I Wire using source logic I would wire everything from p24 through the E stop switch last while it was NC then if necessary I would push the E stop to the NO position?
I'm sure Ive gone severely wrong somewhere. I will probably have other questions as well, but I will read the manual a 3rd time and go from there. I don't want to let the magic black smoke out of the box so I will understand this completely even if it kills me.
Thanks for your time.
EDIT After checking the fwd/off/rev switch I am going to order a single pole 3 position sw. This one may provide feedback issues the way it is laid out and frankly I have enough to contemplate elsewhere. I took some pics as I understand it people like pics? Will load later if I can figure it out.
