MD32460 $MA_TORQUE_OFFSET

(additional torque for electr. weight compensation)

to a value other than zero and activated with the next RESET or POWER ON operation or

with softkey "Activate MD".

Axis with electronic weight compensation

The "electronic weight compensation" function prevents weight-bearing axes from sagging

when the control is switched on. After releasing the brake, the constant weight compensation
