(2) Control by Incremental method (Relative coordinate) (
「
Relative, Single-axis Positioning Control
」
)
(a) Positioning control as much as the goal transfer amount from start position. Unlike the absolute coordinates of
goal position, it is not a value of specified on goal position; it is a moving amount of current position.
(b) Transfer direction shall be determined by the sign of transfer amount.
▷
Transfer direction (+) or no sign: forward direction (current position increase) positioning
▷
Transfer direction ( - ) : reverse direction (current position decrease) positioning
Starting position
Reverse Forward
Amount of movement is - Amount of movement is +
[Example] Set the Relative Coordinates as follow, Operate single-axis positioning control.
▷
Start position: 5000,
▷
Goal position: -7000
This will be reverse direction and positioning will be at the point of –2000.
