Chapter 7 Usage of Various Functions

(2)Coordinate

The coordinate of position data includes Absolute and Incremental

(A)Absolute Coordinate (Control by Absolute method)

This carries out the positioning control from the current position to the goal position (the goal position assigned by

positioning data).

Positioning control is carried out based on the assigned position of origin return or POSPRS command

(origin address).

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)

This carries out the positioning control as much as goal transfer amount from the current position.

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)

Current position

Reverse

Normal

Transfer direction when transfer amount is (+)

Transfer direction when transfer amount is (-)

(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
