Detailed description
2.4 Actions in synchronized actions
Example
ID=1 EVERY $A_IN[1]==1 DO M3 S300
ID = 2 EVERY $A_IN[2]==1 DO M4 S500
ID=3 EVERY $A_IN[3]==1 DO S1000
ID=4 EVERY ($A_IN[4]==1) AND
($A_IN[1]==0) DO SPOS=0
Feed
The feedrate for "Position spindles" can be programmed from a synchronized action with:
FA[Sn]= ...
Note
Only a modal data item is available for the feedrate of synchronized actions for spindle mode
and axis mode. FA[S] and FA[C] are supplied in the same way.
SW limit switches, working area limitations
The restrictions imposed by SW limit switches and working area limitations also apply to
axis/spindle movements activated from synchronized actions.
Influence of limitations on movements from synchronized actions
Working area limitations programmed with G25/G26 are taken into account as a function of
setting data:
SD43400 $SA_WORKAREA_PLUS_ENABLE (Working-area limitation active in the positive
direction)
Activation and deactivation of working area limitations by G functions WALIMON/WALIMOFin
the part program does not affect command axes.
Correcting acceleration
The acceleration specified in the following machine data can be changed in the range from
0% to 200% with ACC[Axis]=0..200 (ACC[Axis]=<Value> (acts in the part program and in
synchronized actions)):
MD32300 $MA_MAX_AX_ACCEL (axis acceleration)
