9 MAIN POSITIONING CONTROL
9.2.3 2-axis linear interpolation control
In "2-axis linear interpolation control" (" Da.2 Control method" = 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 control, addresses established by a machine zero
point return 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 address) set in " Da.5 Positioning address/movement amount".

End point address
When the start point address (current stop position) is (1000, 4000) and the end point address
(positioning address) is (10000, 1000), positioning is carried out as follows.
Axis 1 movement amount (10000-1000=9000)
