Motion synchronous actions
10.5 Technology cycles
If actions that are mutually exclusive are called up in the same interpolation cycle, the action
that is called up from the synchronized action with the higher ID number becomes active.
Example
Axis programs are started by setting digital inputs.
Main program:
ID=1 EVERY $A_IN[1]==1 DO AXIS_X
ID=2 EVERY $A_IN[2]==1 DO AXIS_Y
ID=3 EVERY $A_IN[3]==1 DO $AA_OVR[Y]=0
ID=4 EVERY $A_IN[4]==1 DO AXIS_Z
M30
Technology cycle AXIS_X:
$AA_OVR[Y]=0
M100
POS[X]=100 FA[X]=300
M17
Technology cycle AXIS_Y:
POS[Y]=10 FA[Y]=200
POS[Y]=-10
M17
Technology cycle AXIS_Z:
$AA_OVR[X]=0
POS[Z]=90 FA[Z]=250
POS[Z]=-90
M17
10-68
If
;input 1 is at 1, start axis program X
;input 2 is at 1, start axis program Y
;input 3 is at 1, set the override for
;axis Y to 0
;input 4 is at 1, start axis program Z
