(2) Linear interpolation control with Incremental coordinates
(a) Execute 2 axes linear interpolation from starting position to the goal position. Positioning control is on basis
of the current stop position.
(b) Moving direction depends on the sign of the goal position (Moving amount)
■ The sign is positive (+ or nothing) : Positioning operation in forward
■ The sign is negative (-) : Positioning operation in reverse
[Example] axis X and axis Y are main and sub axis each. Execute linear interpolation by the setting
as follows.
■ Starting position (1000, 4000), Goal position (9000, -3000)
In this condition, the operation is as follows.
■ Setting example of XG5000
