$AA_FXS
INT $AA_FXS[X]
Status "Travel to fixed stop"
0: Axis not at fixed stop
1: Fixed stop successfully approached
2: Fixed stop approach has failed
3: Selection of travel to fixed stop active
4: Deselection of travel to fixed stop active
Axes: Geometry axis, channel axis, machine axis
RS R 2
$AA_COUP_ACT
INT $AA_COUP_ACT[SPI(2)]
Current coupling status of following spindle/following axis:
0: Axis/spindle is not coupled to a leading spindle/leading axis
3: Tangential follow-up of axis
4: synchronized spindle coupling
8: Axis is trailing
16: Following axis of master value coupling
The respective values apply to one coupling. If several couplings are
active for a following axis, this is represented by the sum of the
relevant numerical values.
Axes: Geometry axis, channel axis, machine axis
