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.
