SD42101 DRY_RUN_FEED_MODE
.
A dry run feedrate can be selected in the automatic modes and activated on interruption of an automatic mode or
end of a block. Using machine data:
MD10704 DRYRUN_MASK = 1
, the dry run feedrate can also be activated during execution of the program (in the part program block).
With MD10704 DRYRUN_MASK = 2
, the dry run feedrate can be activated/ deactivated at any time without the axes stopping. The function only
becomes effective with a block which comes later in the program run.

DRY_RUN_FEED_MODE
Effectivity
As long as the "Activate dry run feedrate" interface signal is set, instead
of the programmed feedrates, the feedrate value set in
SD42100 DRY_RUN_FEED
is effective as follows:
0
The maximum value from SD42100 DRY_RUN_FEED and the
programmed velocity is effective. This is the same as the default setting.
1
The minimum value from SD42100 DRY_RUN_FEED and the
programmed velocity is effective.
2
Setting data SD42100 DRY_RUN_FEED is effective directly, regardless
of the programmed velocity.

tapping (
G33,G34,G35

G33,G34,G35
). These functions are executed as programmed.

) and
tapping (
G33,G34,G35
). These functions are executed as programmed.
Note
Activation during machining triggers an internal reorganization task on the control which
causes the axes to be stopped for a short time. This can affect the surface finish of the
workpiece being machined.
