Programming example 1
Cycle is to act as a command for programmer
Main program
N10 G1 X10 G90 F200
N20 X-4 Y6
N30 CYCLE1
N40 G1 X0
N50 M30
Program cycle1
N100 PROC CYCLE1 DISPLOF SBLOF
Suppress single block
N110 R10=3*SIN(R20)+5
N120 IF (R11 <= 0)
N130 SETAL(61000)
N140 ENDIF
N150 G1 G91 Z=R10 F=R11
N160 RET
The cycle CYCLE1 is executed as one step when
single block is active.
Programming example 2
An ASUP run from the PLC for activating modified zero offsets and tool offsets should not
be visible.
N100 PROC NV SBLOF DISPLOF
