Travel to fixed stop

Functionality
This function is available for SINUMERIK 802D sl plus and pro.
The travel-to-fixed-stop (FXS = Fixed Stop) function can be used to establish defined forces
for clamping workpieces, such as those required for sleeves 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.
Programming
FXS[axis]=1
FXS[axis]=0
FXST[axis]=...
FXSW [axis]=...
Note: The machine axis identifier, e.g: X1, should be used as the axis identifier. (X1). The
channel axis identifier (e.g.: X) is only permitted, if no coordinate rotation is active and this
axis is directly assigned to a machine axis.
The commands are modal. The traversing path and the selection of the function FXS[axis]=1
must be programmed in one block.
