Chapter 9 Major Positioning Control
[2] 3-axis linear interpolation control (INC linear 3)
Operation chart
In the incremental system 3-axis linear interpolation control, the designated 3 axes
are used. Linear interpolation positioning is carried out from the current stop
position (start point address) to a position at the end of the movement amount set
in the "[Da.6] Positioning address/movement amount". The movement direction is
determined the sign of the movement amount.
• Positive movement amount .............. Positioning control to forward direction
(Address increase direction)
• Negative movement amount ............. Positioning control to reverse direction
(Address decrease direction)

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.
