Vertical axes

Function 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 (p1511 or p1513). In this way, the holding
torque is specified as soon as the brake has been released.
