With this softkey activated, the part program is executed with no axis or spindle movement. In this
way, you can check the programmed axis positions and auxiliary function outputs of a part program.
This softkey functions the same as the following key on the MCP:
With this softkey activated, all traversing motions are performed with the dry run feedrate defined in
SD42100 DRY_RUN_FEED. You can set the dry run feedrate in the JOG data setting window
through the following operation:
+ →
With this softkey activated, the processing of the program stops at the end of every block containing
M01. In this way, you can check the result already obtained during the machining of a workpiece.
This softkey functions the same as the following key on the MCP:
Note that in order to continue executing the program, press the following key again:
It is possible to skip program blocks, which are not to be executed every time the program runs.
With this softkey activated, the program blocks identified with a slash in front of the block number
(e.g. "/N100") are skipped during machining. Several consecutive blocks can be skipped.
With this softkey activated, the system can interrupt the machining of the workpiece after each
program block. In this way, you can control the machining result block-by-block and check individu-
al machining steps. This softkey functions the same as the following key on the MCP:
The program is advanced to the next block via the following key:
However, for the thread blocks (G33), a stop is performed at the end of the current thread block
only with dry run feedrate activated.
