Vertical axes

Description
With a vertical axis without mechanical weight compensation, electronic weight
compensation can be set by offsetting the torque limits (p1532). The torque limits
specified in p1520 and p1521 are shifted by this offset value.
The offset value can be read in r0031 and transferred in p1532.
To reduce compensation once the brake has been released, the torque offset can
be interconnected as a supplementary torque setpoint (p1513).
In this way, the holding torque is set as soon as the brake has been released.
