M97 Synchronous function
4.17 M Functions
4.17 M Functions
M functions control the program run and the machine components
(machine commands).
M00 Program STOP
The program run stops – ”Cycle Start” resumes the program run.
M01 Optional STOP
The ”optional stop” (Automatic mode) determines whether the
program run stops at M01. ”Cycle start” resumes the program run.
M30 End of program
M30 indicates the end of a program or subprogram. (M30 does not
need to be programmed.)
If you press ”Cycle START” after M30, program execution is repeated
from the start of the program.
M99 Program end with restart at beginning of program or at a
given block number
M99 means ”end program and start again.” CNC PILOT restarts
program execution from:
Program beginning, if NS is not entered
Block number NS, if NS is entered
Modal functions (feed rate, spindle speed, tool number,
etc.) which are effective at the end of program remain in
effect when the program is restarted. You should therefore
reprogram the modal functions at the start of program or
at the startup block (if M99 is used).
M97 Synchronous function
Slides for which M97 is programmed wait until all slides have reached
this sentence. Program run then continues.
For complex machining operations (e.g. machining of several
workpieces), M97 can be programmed with parameters.
Parameters
H: Synchronous mark number – the evaluation takes place only
during interpretation of the NC programs
Q: Slide number – use synchronization with Q if synchronization
with $x is not possible
D: On/Off – default: 0
0: Off – synchronization during runtime of NC program
1: On – synchronization exclusively during interpretation of the
NC programs
Example for M97
. . .
$1 N.. G1 X.. Z..
$2 N.. G1 X.. Z..
$1$2 N.. M97 [$1, $2 wait for each other]
. . .
Machine commands
The effect of the machine commands depends on the
type of lathe. The table below lists the M commands
used on most machines.
For more information on the M commands,
refer to your machine manual.
