4.3.4. Read / write spindle pitch (scaling) „c“ (63h)
This command reads or writes the scaling factor related to the spindle pitch within the range from
0.0000001...9.9999999. Transmission is without decimal point.
Resolution per turn is 2304 steps. A scaling factor of 1.000000 will increase respectively decrease the indicated
value by 23.04 mm.
How to calculate the scaling factor:
Resolution per turn: 23,04 mm (corresponding to length with scaling factor 1.0000000)
Spindle pitch: 4.00 mm
Spindle pitch 4.00
scaling = ───────────────── = ───── = 0,1736111
resolution per revolution 23.04
