4.4 Positioning Mode And Motion Block Data
4.4.1 Motion Mode
The positions are defined either in relation to a fixed reference position (absolute
motion mode), in relation to other positions or a touch-probe sensor. Parameter
Motion Mode 1208 enables the selection.

Motion Mode 1208 = "0 – absolute": An absolute position is a defined position on
the motion path referred to the reference position. The absolute position is ap-
proached independent from the current position value.
Motion Mode 1208 = "1 – relative": A relative position refers to the previous target
position or the current position after JOG mode.
Motion Mode 1208 = "2 – touch probe": rising edge" or "3 – touch probe: falling
edge": a touch probe positioning operation refers to the reference position defined
by a sensor signal.
