9.2.3 2-axis linear interpolation control
Y axis movement
Reverse direction
In "2-axis linear interpolation control" ("
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.)

Operation chart
In absolute system 2-axis linear interpolation control, the designated 2 axes are
used. Linear interpolation positioning is carried out from the current stop position
(start point address) to the address (end point address) set in "

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.
