6 MOTION PROGRAMS FOR POSITIONING CONTROL
[Program Example]
The program which executes the next block at the completion of condition.
1) 00001 WAITON #X10 ;
00002 N1 G01 X100. Y200. F1000. ;
2) 00003 WAITOFF #X11 ;
00004 N2 #2010 = 5 ;
00005 G00 X0. Y-10. ;
3) 00006 WAITON #X12 ;
00007 GOTO 10 ;

The above program is executed as described below.
1) Line 1 When device X10 turns ON, line 2 is executed.
2) Line 3 When device X11 turns OFF, line 5 is executed.
(Line 4 is being executed.)
3) Line 6 When device X12 turns ON, N10 is executed.
4) Line 21 When device XFF turns OFF, #2000=5 to line 27 are executed.
Because of preread processing, N15 is not executed and execution jumps to
N20 if the #2000 (D2000) value is changed from sequence program while
execution waits for XFF to turn from ON to OFF in the WAITOFF statement.
