4.3.4. Read / write parameter spindle pitch (scaling), command „c“ (63h)
This command is utilized to read or write the scaling factor relating to the spindle pitch within the range from
0,0000001...9,9999999. The decimal point is not transmitted.
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 factor = ───────────────── = ───── = 0,1736111
Resolution per turn 23,04
