A program can be interrupted in one of the following ways:
• Pressing the SINGLE BLOCK key on the machine control panel
• NC STOP key or internal signal
• PROGRAM STOP M01 or M00 program modification
• DECODE SINGLE BLOCK (DSB) program modification
• PROGRAM STEP (PST) program modification
• BREAKPOINT (BRK) program modification
• FEED STOP keypress or signal
• Switch to JOG mode
A program can be edited at the breakpoints. The section "Program correction"
describes which type of interruption allows editing without RESET.
Note
The active block display only displays blocks related directly in terms of
traversing logic. Subroutine calls, calculation blocks, etc. are not displayed.
Note
An NC program that only consists of arithmetic blocks and @ commands
cannot be stopped with NC STOP! NC STOP is displayed but the program
continues.
Remedy: Use RESET
