Travel to fixed stop (FXS, FXST, FXSW)

Function
The "Travel to fixed stop" function can be used to establish defined forces for clamping
workpieces, such as those required for tailstocks, quills and grippers. The function can also
be used for the approach of mechanical reference points.
With sufficiently reduced torque, it is also possible to perform simple measurement operations
without connecting a probe. The "travel to fixed stop" function can be implemented for axes
as well as for spindles with axis-traversing capability.
