9   MAJOR POSITIONING CONTROL

[2]   2-axis linear interpolation control (INC linear 2)

 Operation chart

In incremental system 2-axis linear interpolation control, addresses established by
a machine OPR on a 2-axis coordinate plane 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 "

 Positioning

address/movement amount".  The movement direction is determined by the sign of
the movement amount.
