Look at my option 9. I haven't a clue what that means unless it's tied to another input option somehow?
The switch is a "three position" on/off/on. The switch will have three contacts, the center will be "common", one end contact will connect to X4 the other contact to X5. So as on/off/on implies, if the switch is in the center position nothing happens, if the switch is flipped toward X4 then the motor goes forward, if the switch is flipped toward X5 then the motor goes in reverse. With this switch you can't have X4 and X5 on at the same time.
And this makes sense with what he is seeing. You can't have FWD and REV activated at the same time.
I had to tie two contacts and COM together on my PA switch it had 4 connection points.

Did you set these two parameters for x4 and x5 it appears the factory default is idle for both.
I did on mine. Who are you asking?

My instruction are a bit different. It appears to me x4 and x5 are already forward and reverse. I see x6 is by default also a reverse function of some sort but I don't understand what the difference between option 6 "wire reverse operation" and option 9 : wire reversing switch" . My gosh this has me baffled and feeling really stupid.
Can you post a pdf of your instructions?
Oh.... you know what..... It just occurred to me... "wire reversing switch" is probably swapping the direction of FWD and REV.
Don't feel stupid. As I said before these things can be a challenge to get your head around and language translated manuals don't help either.
If everything works but you spindle RPM sensor, then just treat it as a completely separate entity and don't attempt to tie it into the VFD. Others here seem to indicate that's the recommended approach.
As far as your panel goes you're all setup to implement FWD/STOP/REV and JOG FWD/STOP/JOG REV. You just need the right kind of switches. If you can't get them locally I can get them at PA and mail them to you.

So is that a good thing?
I'm not following? I'm guessing that's what "wire reversing switch" is.

Just wondering about your statement. Sometimes communication with just text leaves room for misunderstandings

I puzzled over what my "Forward and reverse switch of drive-by-wire" could possibly mean and it just occurred to me that it might be a poor translation for direction swap. I don't see a programing option on your VFD to swap direction like mine. When I wired in my motor it turned the wrong direction so rather than re-wire it I changed the direction programmatically.

That looks right to me if p53 is set to 5 and p54 is set to 6 which are the factory defaults.
My guess is the x6 is the same as the fwd/rev on the panel?
Most of these types of instructions have something left to be desired in the translation sometimes they can be the most confusing "instructions" anyone has ever seen.

So I'm thinking I have to change switches. I made machine specific control boxes for the switches and tach and would really like to use them if I can with the right switches. The switch in my hand is what I have in the box.
If I understand right I think I can use a single pole double throw switch for the reverse/forward switch instead of the single pole single throw switch I now have.
However I'm not sure what sort of switch I need for the on switch. A momentary switch?

What do you expect ON to do? If all you want to accomplish is FWD/STOP/REV then all you need is one ON-OFF-ON switch. With your box already drilled for two switches I would use two ON-OFF-ON switches and implement FWD/STOP/REV and JOG-FWD/STOP/JOG-REV. Apart from that you could play with the wire reversing option and see how that behaves.

First of all I appreciate yours and others help with this, I know this is getting long so thanks y'all for hanging in there with me.
I want the on switch to turn the spindle on and off, which my present switch does well. However I want the other switch to change spindle directions just like the keypad does. Right now if I throw the reverse switch on it will start the spindle (in reverse) despite my on switch being off.
I hadn't thought about a jog switch as I have never needed one before. I will give it some thought.
I sure wish there were better explanations in the instructions of what the heck all the different ports and configurations do.
I've just had hair brain idea...I will sleep on it and if it is still with me in the morning I will run it by you then.
