NC setting data
The values have the same properties for thread run-in and thread run-out:
<0:
The thread axis is started/decelerated with configured acceleration. Jerk is according
to the current programming of BRISK/SOFT. Behavior is compatible with MD
20650__THREAD_START_IS_HARD = FALSE used until now.
0:
Starting/deceleration of the feed axis during thread cutting is stepped. Behavior is
compatible with MD 20650__THREAD_START_IS_HARD = TRUE used until now.
>0:
The maximum thread starting or deceleration path is specified. The specified distance
can lead to acceleration overload of the axis. The SD is written from the block when
DITR (displacement thread ramp) is programmed.
Note:
MD 10710 $MN_PROG_SD_RESET_SAVE_TAB can be be set so that the value written by the part
program is transferred to the active file system on reset (that is the value is
retained after reset.)
42100 DRY_RUN_FEED
mm/min Dry run feedrate
-
- -
Description:
The feedrate for the active dry run is entered in this setting data. The setting data
can be altered on the operator panel in the "Parameters" operating area.
The entered dry run feedrate is always interpreted as a linear feed (G94). If the dry
run feedrate is activated via the PLC interface, the dry run feedrate is used as the
path feed after a reset instead of the programmed feed. The programmed velocity is used
for traversing if it is greater than the velocity stored here.

42101 DRY_RUN_FEED_MODE
- Mode for dry run velocity
-
- -
Description:
This SD can be used to set the method of operation of the dry run velocity set by
SD42100 $SC_DRY_RUN_FEED.
The following values are possible:
0:
The maximum of SD42100 $SC_DRY_RUN_FEED and the programmed velocity become active.
This is the standard setting and corresponds to the behavior up to SW 5.
1:
The minimum of SD42100 $SC_DRY_RUN_FEED and the programmed velocity become active.
2:
SD42100 $SC_DRY_RUN_FEED becomes active directly, irrespective of the programmed
velocity.
The values 3...9 are reserved for extensions.
