Description:
The value specifies the maximum permitted path deviation for smoothing with G645.
This is only relevant to tangential block transitions that are not acceleration-
continuous.
For smoothing of corner with G645 tolerance MD33100 $MA_COMPRESS_POS_TOL becomes
active like with G642.
34000 REFP_CAM_IS_ACTIVE
- Axis with reference point cam
-
- -
Description:
1:
0:
The referencing cycle starts immediately with phase 2 (see documentation)
Machine axes that have only one zero mark over the whole travel range or rotary axes
that have only one zero mark per revolution do not require an additional reference cam
that selects the zero mark (select MD34000 $MA_REFP_CAM_IS_ACTIVE = 0).
The machine axis marked this way accelerates to the velocity specified in MD34040
$MA_REFP_VELO_SEARCH_MARKER (reference point creep velocity) when the plus/minus
traversing key is pressed, and synchronizes with the next zero mark.
34010 REFP_CAM_DIR_IS_MINUS
- Approach reference point in minus direction
-
- -
Description:
0: MD34010 $MA_REFP_CAM_DIR_IS_MINUS Reference point approach in plus direction
1: MD34010 $MA_REFP_CAM_DIR_IS_MINUS Reference point approach in minus direction
For incremental measuring systems:
If the machine axis is positioned in front of the reference cam, it accelerates,
depending on the plus/minus traversing key pressed, to the velocity specified in
MD34020 $MA_REFP_VELO_SEARCH_CAM (reference point approach velocity) in the direction
specified in MD34010 $MA_REFP_CAM_DIR_IS_MINUS. If the wrong traversing key is
pressed, reference point approach is not started.
If the machine axis is positioned on the reference cam, it accelerates to the velocity
specified in MD34020 $MA_REFP_VELO_SEARCH_CAM and travels in the direction opposite to
that specified in MD34010 $MA_REFP_CAM_DIR_IS_MINUS.
For linear measuring systems with distance-coded reference marks:
If the machine axis has a reference cam (linear measuring systems with distance-coded
reference marks do not necessarily require a reference cam) and the machine axis is
positioned on the reference cam, it accelerates, irrespectively of the plus/minus
traversing key pressed, to the velocity specified in MD34040
$MA_REFP_VELO_SEARCH_MARKER (reference point creep velocity) in the direction opposite
to that specified in MD34010 $MA_REFP_CAM_DIR_IS_MINUS.
