Travel to fixed stop

Description
This function can be used to move a motor to a fixed stop at a specified torque
without a fault being signaled. When the stop is reached, the specified torque is
built up and remains applied.
The desired torque derating is brought about by scaling the upper/motor-mode tor-
que limit and the lower/regenerative-mode torque limit.
Application examples
S Screwing parts together with a defined torque.
S Moving to a mechanical reference point.
