In theory that is a great idea but many times you wouldn't want to re-zero over the center of your work.
Many times I need to jog to an area that has the original raw material height.
Many times this is not in the center of my work.

Makes perfect sense.
Did you add the pause in your post processor or can it be set in Mach4?

I now have added a relay and can turn the spindle on/off from Mach4. Since doing this it seems Mach4 now has no feedback as to what the spindle RPM is.
This causes the pause on start not to work in the spindle setup screen and also trying to check the box that says wait till spindle is at 90% does not work either.

Do I need to add a wire to monitor the spindle speed that the Hitachi VFD is commanding so it can be read in Mach4 or am I missing something else?

Craig
Thanks for your expert assistance.
I will use a relay as I can certainly understand why one would want to totally isolate the spindle so there is no spurious unsafe start of the spindle.

Is it possible to use the G540 Pin 7 VFD Ground to turn on the spindle.
It seems like I read somewhere that it is possible to use this method?
Does this seem correct?

Is an external relay required to turn the spindle on & off? Still stumped on why no On & Off from Mach4 but can control Spindle speed from Mach4 once VFD Run button pressed.

A002 to 01, right next to A001 which you must have already changed to get terminal control of speed/frequency. If it's set to 01 already then you have a Mach setup/wiring issue. But, really, is MUST be set to 02 to have control panel control of on/off!!

I think!!

It is very close to working correctly. Most likely parameters and not wiring. Since once I press the run button on the VFD I'm able to start & stop it and change the speed all from the mach 4 screen. So it just isn't getting a signal to initiate the run command when I'm trying to start the VFD initially from Mach 4.

What about A005? This one I'm not totally sure of what it is supposed to be set at.

I believe that is where the problem is at this point.
I have control of the VFD via Mach 4 once the Run button is pressed on the VFD.
I'm just not able to command it to Run/Stop from Mach 4.
I have a Hitachi WJ200 so I need to figure out which parameter on the VFD to change to enable remote Run/Stop Command.

How is it that? Once it is running I can then control it in Mach4?
So it doesn't seem like I need to change any setting in the VFD.
I have it set to be controlled by Analog Voltage 0-10VDC input.
It is a Hitachi WJ200-022SF if it matters.

I've seen where some people use a relay to turn the VFD spindle on and off is the necessary in my case as well? But also thought I read somewhere this is not necessary for a G540.
