Operation chart
In increment system 2-axis linear interpolation control, addresses established by a
machine zero point return 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.5
Positioning address/movement amount". The movement direction is determined
by the sign of the movement amount.

Example
When the axis 1 movement amount is 9000 and the axis 2 movement amount is -3000, positioning is
carried out as follows.
