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.

10 As for configured value 0 except for thread cutting (G33,G34,G35) and
tapping (G33,G34,G35). These functions are executed as programmed.
11 As for configured value 1 except for thread cutting (G33,G34,G35) and
tapping (G33,G34,G35). These functions are executed as programmed.
12 As for configured value 2 except for thread cutting (G33,G34,G35) 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.
