Holding torque
This parameter is utilized to enable respectively disable the motor holding torque. Both directional signals “motor
ccw” and “motor cw” are activated by the spindle position display (SPA). Thus, the motor is hold at its actual
position. Refer also to command „DB“ for temporary holding torque disabled.

0 = Off

holding torque disabled

1 = On

holding torque enabled

4.3.4. Read / write spindle pitch (scaling) „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 1440 steps. A scaling factor of 1.000000 will increase respectively decrease the indicated
value by 14.4 mm.

How to calculate the scaling factor:
Resolution per turn: 14.40 mm (corresponding to length with scaling factor 1.0000000)
Spindle pitch:

4.00 mm

Spindle pitch 4.00
scaling = ───────────────── = ───── = 0.2777777

resolution per revolution 14.40
