(2) Control by Incremental method (
「
Incremental, Single-axis Position Control
」
)
(a) It moves the object as much as the target moving amount from start position. Unlike the target position of the
absolute coordinate, the value specified on target position is not position value. That is a transfer amount
from the current position.
(b) Transfer direction is determined by the sign of moving amount.
▷
Transfer direction (+) or no sign: forward direction positioning (current position increases)
▷
Transfer direction ( - ) : reverse direction positioning (current position decreases)
Starting position
Reverse Forward
Amount of movement is - Amount of movement is +
[ Example ] Executes Absolute coordinate, single-axis position control with the following setting
▷
Start position: 5000,
▷
Target position: -7000
It goes to reverse direction and stops at the
–2000.
