Remarks
Avoidance of multiple selection
The "Travel to fixed stop" function must only be switched on once per axis. In the event of an
error, alarm 20092 is displayed and the corresponding alarm response takes effect.
To avoid multiple selections, it is recommended that a selection marker be used in the
synchronized action.
Example:
Program code
N10 R1=0
...
N20 IDS=1 WHENEVER ($R1==0 AND $AA_IW[AX3] > 7) DO $R1=1 FXS[AX1]=1
Switching on during the approach motion
"Travel to fixed stop" can also be switched on during the approach motion through a non-
modal synchronized action.
Example:
Program code
N10 G0 G90 X0 Y0
...
