9 MAJOR POSITIONING CONTROL
[2] 2-axis linear interpolation control (INC linear 2)
Operation chart
In incremental system 2-axis linear interpolation control, designated 2 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.
