1-6
[ Example ]
■ Starting Position : 5000
■ Goal Position : -7000
In this condition, it moves reversely and positions at -2000.
1.4.2 Interpolation Control
(1) Linear Interpolation Control
Execute Linear interpolation control with designated axis at starting position (Current position).
There are two methods for linear interpolation control (control by absolute coordinate and control by incremental
coordinate)
(a) Linear interpolation by absolute coordinates
1) Execute Linear interpolation from starting position to goal position designated by positioning data.
2) Positioning control is executed from the position that homing designated.
3) Movement direction is designated by starting position & goal position of each axis.
■ Starting position < Goal position : Positioning operation with forward direction
■ Starting position > Goal position : Positioning operation with reverse direction
[ Example ]
■ Starting Position (1000, 4000)
■ Goal Position (10000, 1000)
In this condition, operation is as follows.
