If you want to check previously obtained results while machining a
workpiece, you can have the machining stop at specially marked
points (programmed stop). Within the sequential control program, the
stop occurs at the "safety distance" position.
Conversely, if you do not want to execute certain machining steps
programmed in G codes on every program run, you can mark these
blocks accordingly (skip G code blocks). This is not possible with
sequential control blocks.
You can also choose to allow DRF offsets, i.e. offsets with the
handwheel, during machining. This function must be set up by the
machine manufacturer.
Please also refer to the machine manufacturer's instructions.
Load a program in "Machine Auto" mode (see Sec.
"Starting/stopping program execution").
Press the "Prog. Cntrl." softkey.
Press the "Program. stop" softkey.
Press the "Cycle Start" key.
Execution of the program starts. The program stops at each block for
which the G-code command "M01" was programmed (see Sec. "G-
code in the sequential control program").
Press the "Cycle Start" key again each time.
Execution of the program is continued.
Press the "Program. stop" softkey again if you want the program
to be executed without a programmed stop. (The softkey is
deactivated again.)
Load a program in "Machine Auto" mode (see Sec.
"Starting/stopping program execution").
Press the "Prog. Cntrl." softkey.
Press the "Skip" softkey.
Press the "Cycle Start" key.
Execution of the program starts. G code blocks with the "/" character
(slash) in front of the block number are not executed.
