(b) 2-axis linear interpolation control
(Note-1)
This controls interpolation along a linear locus from the start point address
(current stop position) defined by two axes.
[Control using the absolute system]
1) This performs linear interpolation using two axes from the start point
address to the specified address.
2) The start point address and the specified address determine the
direction of travel.
[Example]
The operation when the start point address is 800 for axis 1 and 2000
for axis 2 and the positioning address specified to 2000 for axis 1 and
8000 for axis 2, is shown below.

[Control using the increment system]
1) This performs positioning to the composite position of the travel
direction and the travel increment specified by each axis from the start
point address.
2) The sign of the travel increment determines the direction of travel.
• For positive travel increment……Positioning in the positive direction
(direction of address increase)
• For negative travel increment……Positioning in the negative direction
(direction of address decrease)
[Example]
The operation when the start point address is 800 for axis 1 and 2000
for axis 2 and the positioning address specified to 1200 for axis 1 and
6000 for axis 2, is shown below.

REMARK
(Note-1): The interpolation speed during linear interpolation control can be selected
from "composite speed" and "reference axis speed" using the interpolation
speed designation method of detailed parameter 1. (Refer to Section 5.2.3
information about setting "[Pr.20] Interpolation speed designation method"
of the detailed parameter 1.)
