Position display
The position actual value display shows the actual values of both the leading axis and the synchronized axes. The same
applies to the service display values in the system data operating area.
Software limit switch
The SW limit switch monitor is processed for the leading axis only. If the leading axis crosses the limit switch, all axes in the
gantry grouping are braked to a standstill.

Example
7.7.1
Creating a gantry grouping
Introduction
The individual steps involved in the process are explained below using an example constellation:
● Setting up a gantry grouping
● Referencing its axes
● Aligning any offsets
● Synchronizing the axes involved
Constellation
Machine axis 1 = gantry leading axis, incremental measuring system
Machine axis 3 = gantry synchronized axis, incremental measuring system
The following MD describes the output values. Individual settings must be corrected or added later according to the
information below.
Gantry machine data
Axis 1:
MD37100 GANTRY_AXIS_TYPE = 1
MD37110 GANTRY_POS_TOL_WARNING = 0
MD37120 GANTRY_POS_TOL_ERROR = 1 mm
MD37130 GANTRY_POS_TOL_REF = 100 mm (max. misalignment)
MD37140 GANTRY_BREAK_UP = 0
Axis 3:
MD37100 GANTRY_AXIS_TYPE = 11
MD37110 GANTRY_POS_TOL_WARNING = 0
MD37120 GANTRY_POS_TOL_ERROR = 1 mm
MD37130 GANTRY_POS_TOL_REF = 100 mm (max. misalignment)
MD37140 GANTRY_BREAK_UP = 0
Reference point machine data
The MD values specified apply for the first encoder in both axis 1 and axis 3.
MD34000 REFP_CAM_IS_ACTIVE = TRUE
MD34010 REFP_CAM_DIR_IS_MINUS = e.g. FALSE
MD34020 REFP_VELO_SEARCH_CAM =
MD34030 REFP_MAX_CAM_DIST = corresponds to max. distance traversed
MD34040 REFP_VELO_SEARCH_MARKER =
