(2) Coordinate
• The coordinate of position data includes Absolute and Incremental
(A) Absolute Coordinate (Control by Absolute method)
① This carries out the positioning control from the current position to the goal position (the goal position assigned by
positioning data).
② Positioning control is carried out based on the assigned position of origin return or POSPRS command
(origin address).
③ Transfer direction shall be determined by the current position and goal position.
- Start position < Goal position : forward direction positioning
- Start position > Goal position : reverse direction positioning
(B) Relative Coordinate (Control by Incremental method)
① This carries out the positioning control as much as goal transfer amount from the current position.
② Transfer direction shall be determined by the sign of transfer amount.
- When transfer direction is (+) or no sign : normal direction positioning (position increase direction)
- When transfer direction is ( - ) : reverse direction positioning (position decrease direction)
(3) Operation Mode (End / Keep / Continuous)
•
Operation Mode is divided into following three kinds.
• For the details, please refer to ‘3) Operation mode’ in chapter 7.3.2

(4) Operation Method (Single/Repeat)
• Select operation method : Single operation or Repeat operation.
• For the details, please refer to ‘4) Operation method’ in chapter 7.3.2

(5) Positioning Address
• This is the area to set the transfer amount of position data as “positioning address”.
• The setting range is –2,147,483,648 ∼ 2,147,483,647(setting unit: Pulse).
• The change of position address value is available when assigned by D area
