(2) 2-axis linear interpolation control (INC linear 2)
(a) Operation chart
In incremental system 2-axis linear interpolation control, designated 2 axes are used. Linear interpolation
positioning of movement amount set in "[Da.6] Positioning address/movement amount" is carried out from the
current stop position (start point address). The movement direction is determined by the sign of the movement
amount.

When the axis 1 movement amount is 9000 and the axis 2 movement amount is -3000, positioning is

(b) Restrictions
An error will occur and the positioning will not start in the following cases. The machine will immediately stop if
the error is detected during positioning control.
• If the movement amount of each axis exceeds "1073741824 (=2
