Chapter 9 Major Positioning Control
9.2.3 2-axis linear interpolation control
In "2-axis linear interpolation control" ("[Da.2] Control system" = ABS linear 2, INC
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.)
[1] 2-axis linear interpolation control (ABS linear 2)
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 "[Da.6] Positioning
address/movement amount".

End point address
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.
