After executed by the start positioning operation command (「Direct start」, 「Indirect start」,
「Simultaneous start」), positioning control from specified axis (the current stop position) to goal position (the
position to move).
(1) Control by Absolute method (Absolute coordinate)
(a) Positioning control from start position to goal position (the position assigned by positioning data). Positioning
control is carried out based on the position assigned (origin position) by homing.
(b) Transfer direction shall be determined by start position and goal position.
▶Start position < Goal position: forward direction positioning
▶Start position > Goal position: reverse direction positioning
[Example] Set the Incremental Coordinates as follow, Operate shortening positioning control.
▷Start position: 1000,
▷Goal position: 8000
The transfer amount to forward direction shall be 7000 (7000=8000-1000).
