9 MAJOR POSITIONING CONTROL
[2] 3-axis linear interpolation control (INC linear 3)
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.
