Scaling of the hydraulic limits
Using the scaling parameter Hyd_Limit (P 2872) allows the respective currently
active limit to be scaled for each motion block. This makes it possible to limit each
individual process. The scaling is switched over dynamically with the respective
control mode that is set. The following table shows for which control modes the
scaling function is implemented.

Wait time in Auto mode
After expiration of the waiting time, there is a branch to the motion block specified in
the “subsequent motion block Time Ctrl” (2865 HYD_TabNextIdx). The respective
motion block is only active for the duration of the waiting time, regardless of whether
or not the target has been reached.
