11.4 Program section repetition
Fundamentals
11-10 Programming Manual, 10.2004 Edition, 6FC5 298-7AB00-0BP1
Example of repetition of positions
N10 POSITION1: X10 Y20
N20 POSITION2: CYCLE(0,,9,8) ;Position cycle
N30 ...
N40 REPEATB POSITION1 P=5 ;Execute BLOCK N10 five times
N50 REPEATB POSITION2 ;Execute block N20 once
N60 ...
N70 M30
Example 5 squares with increasing width are to be produced
N5 R10=15
N10 Begin: R10=R10+1 ;Width
N20 Z=10-R10
N30 G1 X=R10 F200
N40 Y=R10
N50 X=-R10
N60 Y=-R10
N70 Z=10+R10
N80 REPEAT BEGIN P=4 ;Execute area from N10 to N70 four times
N90 Z10
N100 M30
Example repeat program section from BEGIN to END
N5 R10=15
N10 Begin: R10=R10+1 ;Width
N20 Z=10-R10
N30 G1 X=R10 F200
N40 Y=R10
N50 X=-R10
N60 Y=-R10
N70 END:Z=10
N80 Z10
N90 CYCLE(10,20,30)
N100 REPEAT BEGIN END P=3 ;Execute area from N10 to N70 three times
N110 Z10
N120 M30
