Programmed stop: M0
The machining is stopped in the NC block with
etc.
Programmed stop 1 - optional stop: M1
can be set via:
M1
● HMI / dialog box "Program Control"
● NC/PLC interface
The program execution of the NC is stopped by the programmed blocks.
Programmed stop 2 - an auxiliary function associated with M1 with stop in the program
execution
Programmed stop 2 can be set via the HMI / dialog box "Program Control" and allows the
technological sequences to be interrupted at any time at the end of the part to be machined.
In this way, the operator can interrupt the production, e.g. to remove chip flows.
End of program: M2, M17, M30
A program is terminated with
program is called from another program (as subroutine),
and vice versa, i.e.
Spindle functions: M3, M4, M5, M19, M70
The extended address notation with specification of the spindle number applies for all
spindles.
Example:
Program code
M2=3
If an address extension has not been programmed, the function applies for the master
spindle.
