< Figure 3-7 operation of linear interpolation control >
(2) Control by incremental coordinates
It executes the linear interpolation control based on current position by incremental coordinates.
At this time, Address of operation data means how long object moves from current position.
Direction is determined sign of Address.
• In case Address is positive number: forward
• In case Address is negative number: backward
(a) Example
•
It assumes that operation data is specified as shown table 3-7 and current position are
X=1000 , Y=4000.
