Axis Definition

[cmcdonald]

Is there a way to get a axis definition into a P or M variable?

 

 

I want to a plc to calculate a scale factor based on the axis definition. I have several machines that i want to update and they have different axis definitions (gear ratios) for motor 1 and motor 2.

 

Thanks

From manual sugested M vars

Motor #1 Axis Definition Registers

M191->L:$0000CF ; #1 X/U/A/B/C-Axis scale factor (cts/unit)

M192->L:$0000D0 ; #1 Y/V-Axis scale factor (cts/unit)

M193->L:$0000D1 ; #1 Z/W-Axis scale factor (cts/unit)

M194->L:$0000D2 ; #1 Axis offset (cts)

Motor #2 Axis Definition Registers

M291->L:$00014F ; #2 X/U/A/B/C-Axis scale factor (cts/unit)

M292->L:$000150 ; #2 Y/V-Axis scale factor (cts/unit)

M293->L:$000151 ; #2 Z/W-Axis scale factor (cts/unit)

M294->L:$000152 ; #2 Axis offset (cts)

I have found it useful to add these as we for adding and removing axes under program control.

M190->Y:$0000C0,16,4,U ; #1 CS Type Register None=0 A=1, B=2 C=3 UVW =4 XYZ = 7, I=5 (Kinematic)
