9 MAJOR POSITIONING CONTROL
Forward direction
Z axis
movement amount
Reverse direction
Example
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.
Axis 3
6000
Axis 3 movement

[2] 3-axis linear interpolation control (INC linear 3)
Operation chart
In the incremental system 3-axis linear interpolation control, using an address
established by a machine OPR in the 3-axis coordinate space, a 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 "
Positioning address/movement amount". The movement direction depends on the
sign (+ or -) of the movement amount.
