NC setting data
Description: The SD is active for thread cutting with G33 (G34, G35).
It features two elements that define the behavior of the thread axis during
runup (1st element) and during deceleration/smoothing (2nd element).
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.)
Description: The feedrate for the active dry run is entered in this setting data. The set-
ting 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.
