machine coordinate system). An interface signal from the PLC can be used to select whichever of the two SW limit switches 1

or 2 is to be active.

REFP_CAM_DIR_IS_MINUS (A, M)

MD 34010: $MA_REFP_CAM_DIR_IS_MI-

NUS

Direction of the reference point approach

The variable specifies the direction of the reference point approach.

For incremental measuring systems:

If the machine axis is positioned in front of the reference cam, it accelerates according to 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_VE-

LO_SEARCH_CAM and travels in the opposite direction 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 if the

machine axis is positioned on the reference cam, it accelerates, irrespective of the plus/minus traversing key pressed, to the

velocity specified in MD34040 $MA_REFP_VELO_SEARCH_MARKER

(reference point creep velocity) in the opposite direction to that specified in

MD34010 $MA_REFP_CAM_DIR_IS_MINUS.

Return value

o 0: MD34010 $MA_REFP_CAM_DIR_IS_MINUS reference point approach in the plus direction
