Working area limitation in the workpiece coordinate system/SZS
Coordinate-system-specific working area limitation (WALCS0 ... WALCS10) is not effective in
the block with G75. The destination point is monitored as the starting point of the following block.
Axis/Spindle movements with POSA/SPOSA
If programmed axes/spindles were previously traversed with POSA or SPOSA, these
movements will be completed first before the fixed point is approached.
Spindle functions in the G75 block
If the spindle is excluded from "fixed-point approach", then additional spindle functions (e.g.
positioning with SPOS/SPOSA) can be programmed in the G75 block.
Modulo axes
In the case of modulo axes, the fixed point is approached along the shortest distance.
2.14.6 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.
