9 MAJOR POSITIONING CONTROL
9.2.3 2-axis linear interpolation control
In "2-axis linear interpolation control" ("
linear 2), two motors are used to carry out position control in a linear path while
carrying out interpolation for the axis directions set in each axis.
(Refer to Section 9.1.6 "Interpolation control" for details on interpolation control.)

Example
When the start point address (current stop position) is (1000, 1000) and the end point address
(positioning address) is (10000, 4000), positioning is carried out as follows.
Operation chart
In absolute system 2-axis linear control, addresses established by a machine OPR
on a 2-axis coordinate plane are used. Linear interpolation positioning is carried
out from the current stop position (start point address) to the address (end point
