Program control

Single block
Single block mode can be activated for startup of the program. For this purpose a program
stop occurs after each traversing block.
Work plan programs maintain the alternative of stopping processing after each plane infeed.
Program test
Programs can be checked before processing in a program test mode. The program is
executed to completion with stationary axes. This is especially meaningful in connection with
the simultaneous recording option (real-time simulation).
Reduced rapid traverse
You have the facility of additionally limiting the traversing speed for rapid traverse so that
when running-in a new program with rapid traverse, no undesirable high traversing speeds
occur. In the rapid traverse mode, the traversing speed of the axes is reduced to the
percentage value (0-100%) entered in RG0.
Program editing
In machine condition STOP, the program can be edited directly at the location of the fault,
e.g. erroneous DIN/ISO blocks or wrongly parameterized sequences. After correcting the
program you can continue machining.
Repositioning to the contour (REPOS)
In machine condition STOP, the machining axes may be moved to and away from the
workpiece surface with the handwheel or the direction keys.
Highlights
● Secure positioning of new part programs
● Continue machining quickly after interruptions
