Machine data
The following machine data describes the original values at the beginning of the procedure.
Individual settings must be corrected or added later according to the information below.
Gantry machine data
Axis 1
MD37100 $MA_GANTRY_AXIS_TYPE = 1 (gantry axis definition)
MD37110 $MA_GANTRY_POS_TOL_WARNING =0 (gantry warning limit)
MD37120 $MA_GANTRY_POS_TOL_ERROR = e.g. 1 (gantry trip limit)
MD37130 $MA_GANTRY_POS_TOL_REF = e.g. 100 mm (max. misalignment) (gantry
shutdown limit when referencing)
MD37140 $MA_GANTRY_BREAK_UP = 0 (invalidate gantry axis grouping)
Axis 3
MD37100 $MA_GANTRY_AXIS_TYPE= 11
MD37110 $MA_GANTRY_POS_TOL_WARNING = 0
MD37120 $MA_GANTRY_POS_TOL_ERROR = e.g. 1 mm
MD37130 $MA_GANTRY_POS_TOL_REF = e.g. 100 mm (max. misalignment)
MD37140 $MA_GANTRY_BREAK_UP = 0
Reference point machine data (for first encoder each)
Axis 1
MD34000 $MA_REFP_CAM_IS_ACTIVE = TRUE
MD34010 $MA_REFP_CAM_DIR_IS_MINUS = e.g. FALSE
MD34020 $MA_REFP_VELO_SEARCH_CAM =
MD34030 $MA_REFP_MAX_CAM_DIST = corresponds to max. distance traversed
MD34040 $MA_REFP_VELO_SEARCH_MARKER =
MD34050 $MA_REFP_SEARCH_MARKER_REVERSE = e.g. FALSE
MD34060 $MA_REFP_MAX_MARKER_DIST = Difference betw. cam edge and 0 mark
MD34070 $MA_REFP_VELO_POS =
MD34080 $MA_REFP_MOVE_DIST = 0
MD34090 $MA_REFP_MOVE_DIST_CORR = 0
MD34092 $MA_REFP_CAM_SHIFT = 0
MD34100 $MA_REFP_SET_POS = 0
MD34200 $MA_ENC_REFP_MODE = 1
The reference point machine data (for the first encoder) of axis 3 must be specified analogously.
