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.

Operation chart
In incremental system 3-axis linear interpolation control, designated 3 axes are
used. Linear interpolation positioning of movement amount set in "
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.
