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 "
Da.6
 Positioning 
address/movement amount".  The movement direction is determined by the sign of 
the movement amount.

When the axis 1 movement amount is 9000 and the axis 2 movement amount is -3000, positioning
address (10000, 4000) is carried out as follows.
