Detailed Description
2.8 Single block
Cycle
Example 1: A cycle is to act like a command for the user.
Main program:
N10 G1 X10 G90 F200
N20 X-4 Y6
N30 CYCLE1
N40 G1 X0
N50 M30
Program cycle:1
N100 PROC CYCLE1 DISPLOF SBLOF
N110 R10=3*SIN(R20)+5
N120 IF (R11 <= 0)
N130 SETAL(61000)
N140 ENDIF
N150 G1 G91 Z=R10 F=R11
N160 M17
CYCLE1 is processed for an active single block, i.e., the Start key must be pressed once to
process CYCLE1.
Example 2: An ASUB, which is started by the PLC in order to activate a modified zero offset
and tool offsets, is to be executed invisibly.
