I do not immediately see anything wrong with your parameters or PLC program, except that you should probably have Parameter 1 set to 3 (instead of 1) if you have front-mount tooling.

When you do programmed moves (e.g. "G0 Z0", "G0 Z1", "G0 X0", "G0 X1" at the F3/MDI prompt) does the correct axis move? Or does Z move when you give a programmed move for X, and vice versa?

When the Z axis is moving, which axis changes on the DRO position display?

On further review, I see in Chris's comments in your PLC program that you have a vertical lathe. Do you think that might be relevant to your issue?

If you have a T400 console with the standard vertical lathe jog panel (right side tools), then the Z+ jog button would point up; the Z- jog button would point down; the X- jog button would point left; and the X+ jog button would point right.

In that case, you would usually set Parameter 1 = 12: +4 to swap the axis 1 and 2 jog buttons; and +8 to display vertical-lathe graphics on the screen.

Thanks guys. setting parm 1 = 12 fixed the problem
