Traversing spindles (M, S, SPOS)

Spindles can be started, positioned and stopped via synchronized actions. The programming
is performed in the action part of the synchronized action with the same syntax as in the part
program. Without numeric extension the commands for the master spindle apply. By
specifying a numeric extension, it is possible to program each spindle individually:
Program code
ID = 1 EVERY $A_IN[1]==1 DO M3 S1000
ID = 2 EVERY $A_IN[2]==1 DO SPOS=270
ID = 1 EVERY $A_IN[1]==1 DO M1=3 S1=1000 SPOS[2]=90
If concurrent commands are specified for a spindle through synchronized actions that are
active in parallel, the chronological sequence decides the activation.
User-specific spindle enable
The start of spindle motions at defined times can be achieved via synchronized actions by
blocking the motion programmed in the part program.
Example:
The spindle is programmed within a part program and should not start at the beginning of the
block, but only when input 1 is set. The synchronized action holds the spindle override at 0%
until the enable via input 1. See Section "Override ($A...OVR) (Page 34)".
Program code
; As long as input 1 is not set => spindle override = 0%
ID=1 WHENEVER $A_IN[1]==0 DO $AA_OVR[S1]=0
...
; The start of the spindle is triggered
; The spindle is enabled when input 1 is set
