(2) 3-axis linear interpolation control (INC linear 3)
(a) Operation chart
In incremental system 3-axis linear interpolation control, designated 3 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.
Ex.
When the axis 1 movement amount is 10000, the axis 2 movement amount is 5000 and the axis 3
movement amount is 6000, positioning is carried out as follows.
