You need to configure the VFD and/or wire your spindle motor to run the correct direction in high range. There is no "reverse in high range" parameter. Typically you would swap two of the power leads coming out of the VFD (U, V and W).

There is also no high range speed ratio Parameter, as such. P65 ...

I assume that, when you say "#3", you really mean INP13, named "SpinLowRange_I" or something similar.

Set Parameter 65 to the ratio of low range speed to high range speed (0.193, in your example).

Assuming you have a typical back gear assembly, so that the spindle turns the opposite direction when ...

There is a loophole in ATCMoveZAxisStage, where it will only proceed if the tool pot is in the up (idle) position.

Since the pot will swing down as soon as the carousel is in position, that causes the pot to be out of the expected position by the time Z axis movement is acknowledged, if the ...

Yes, if it were any ordinary PLC-reported fault condition, then pressing and releasing emergency stop would reset it.

If your problem were directly related to the emergency stop button, then you could replicate the problem simply by pressing and then releasing emergency stop.

In your picture of ...

You could use the PLC Detective logic analyzer to log when, and for how long, the EStopOk input was open; and whether any other inputs opened at the same time.

I came in this morning at 9AM, and it was in e-stop state. It generated a weekly report too. Restarting CNC12 didn’t fix it. I had to quit ...

When you use the F8/Graph key in CNC12 to preview the program before you try running it, you can look at the scales/rulers on the Graph screen to see where the toolpath cuts, relative to the WCS X0 Y0 Z0.

BTW, the PLC has nothing whatsoever to do with WCS locations or G code interpretation.

If you can find them in a pre-update report or in a backup of the pre-update cncm folder, and they were not corrupted back then, then it would work to restore those copies.

Reinstalling CNC12 and choosing to install a factory-supplied PLC program would give you fresh factory-standard macros, but it ...

Assuming that your 6/6/25 v5.26 report is still current, your M3 and M4 (and M7 and M8) macro files have been corrupted.

All the characters in those macro files have been replaced with zero (NUL) bytes.

That is probably why you cannot start the spindle in Auto mode at the MDI prompt (although I do ...

In general, you can keep the spindle off simply by selecting Manual spindle mode. In Manual spindle mode, M3 and M4 cannot start the spindle.

Unfortunately, the factory-supplied M3 and M4 macros prevent you from proceeding without changing back to Auto spindle mode (at which point they they start ...
