how to reference LimitAll input in M91 (Resolved)

[Allin1Chris]

Hey pmchoudek,

What both Keith and Marty suggests would be a good way to ensure that everything would work properly. However i do see you have a custom PLC and may be difficult for you to move over your custom logic over to the new PLC.

For M91/M92 program looks at the inputs defined in the Motor screen of the software and not the PLC definition. The wizard sets this up for you when you assign an home input. But you will have to do it manually if you wish to not start fresh.

To use M91 for your X and Y axis, Navigate to Setup (F1) > Config (F3) > Mach. (F2) > Motor (F2). Here under Home - you will want to Input "6" for both X and Y axis. This will designate that Input 6 is your home switch for these two axis and M91 will now look for input 6. IF your using M92 you will ofcourse need to put the number under Home +.

In your home Program simply having the following should work.
M91 /X L1
M26 /X
M91 /Y L1
M26 /Y

Let us know if that works for you.

YES!! That worked Chris.

All I had to do was change the 'Home -' in the parameters to input 6 for both axes.

Now my M91 command works for both X and Y axis.

Thanks for the help!
