Work preparation
3.2 Subprogram technique
Example 2: A cycle is to act like a command for a user
Initial situation: Single block machining is active.
Main program:
Program code
...
N100 G1 X10 G90 F200
N120 X-4 Y6
N130 CYCLE1
N140 G1 X0
N150 M30
Cycle CYCLE1:
Program code
N100 PROC CYCLE1 DISPLOF SBLOF
N110 R10=3*SIN(R20)+5
N120 IF (R11 <= 0)
N130
N140 ENDIF
N150 G1 G91 Z=R10 F=R11
N160 M17
The cycle CYCLE1 is processed with active single block machining. CYCLE1 is processed for
active single block machining, i.e. the Start key must be pressed once to process CYCLE1.
Example 3: An ASUB, which is started by the PLC in order to activate a modified zero offset and
tool offsets, is to be executed invisibly
Program code
N100 PROC NV SBLOF DISPLOF
