Detailed description
3.7 Actions in synchronized actions
Program code
; Continuous measurement: Mode = 1 (simultaneously), FIFO memory = 1,
; trigger event 1 = 1 (rising edge of probe 1),
; trigger event 2 = -1 (falling edge of probe 1)
N30 MEAC[X]=(1, 1, 1, -1) POS[X]=100
N40 MEAC[X]=(0)
N50 STOPRE
N60 R0 = $AC_MARKER[1]
Example 3
Rising and falling edges of probe 1 are to be recorded between 0 and 500 mm for the X axis.
The number of measurements is limited to 10.
The distance-to-go of the X axis is then deleted.
Program code
N10 G0 X0
; Abort condition: Deselect continuous measurement after 10 or more measurements
; and perform "delete distance-to-go"
N10 WHEN $AC_FIFO1[4] >= 10 DO MEAC[X]=(0) DELDTG(X)
; Continuous measurement: Mode = 1 (simultaneously), FIFO memory = 1,
; trigger event 1 = 1 (rising edge of probe 1),
; trigger event 2 = -1 (falling edge of probe 1)
N20 MEAC[X]=(1, 1, 1, -1) G01 X100 F500
N30 MEAC [X]=(0)
N40 R0 = $AC_FIFO1[4]

Travel to fixed stop (FXS, FXST, FXSW, FOCON, FOCOF, FOC)

Function
Travel to fixed stop
The function "Travel to fixed stop" can be controlled via synchronized actions with the FXS,
FXST and FXSW commands.
The activation can also be performed without traversing motion of the relevant axis. The torque
is immediately limited. The fixed stop is monitored as soon as the axis is traversed.
Travel with limited torque/force
Travel with limited torque/force can be controlled via synchronized actions with the FOCON,
FOCOF and FOC commands.
Syntax
FXS[<axis>]=<request>
