Chapter 4 Positioning Parameter & Operation Data
4-30
4.8.2 Operation Data Setting
(1) Step No
(a) The setting range of positioning data as serial no. is 0
∼
400.
(b) The first Starting step of operation data is no.1 step.
Notes
In case of designating step number as ‘0’ with indirect start, Simultaneous start, Position synchronous start, it means
current operation step.
(2) Coordinate
(a) Coordinate of position data includes absolute coordinate and incremental coordinate.
1) Absolute Method
a) This carries out the positioning control from the current position to the goal position
(the goal position assigned by positioning data).
b) Positioning is carried out based on the assigned position of homing (origin address).
c) 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
[Example]
■ When current position : 1000 , Goal position : 8000, forward direction transfer amount is 7000(8000-1000).
Notes
Positioning by Absolute method (Absolute coordinate) can start only in the state that the origin is determined.
If starting in the state that the origin is not determined, Error will occur.
2) Incremental method
a) This carries out the positioning control as much as goal transfer amount from the current position.
b) Transfer direction shall be determined by the sign of transfer amount.
.
■ When transfer direction is (+) or no sign : forward direction positioning (position increase direction)
■ When transfer direction is ( - )
: reverse direction positioning (position decrease direction)
