Linear Interpolation
10-4 Linear Interpolation
10-4-1 Two-axis Linear Interpolation
Overview
Operation Example
Setting the Unit
• Used for carrying out positioning on multiple active axes.
• The only interpolation method available is linear interpolation.
• The positioning sequence for the active axis designates the axes to be used in
interpolation.
In the following example, the program carries out an automatic interpolation
operation, then returns to the origin and stops.
Y axis
When the operation start switch is turned ON, the following positioning is auto-
matically executed in the given order, using linear interpolation, and then posi-
tioning is stopped.
(X,Y) = (5000, 1000) → (0, 2000) → (5000, 3000) → (0, 4000) → (5000, 5000) →
(5000, 0) → (0, 0)
The interpolation speed at this time is 500 pps.
(Set the origin of both the X and Y axes beforehand to "0" by either conducting an
origin search or executing PRESENT POSITION CHANGE).
