7-4 Linear Interpolation
CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Linear interpolation is a function to perform positioning with axes 1 to 4 so that the point at
which the axis currently stops and the specified point are aligned on a straight line.
For setting details, refer to "Linear Interpolation Operation" on page 7-21.
The chart below shows a linear interpolation of 2 axes, namely axes 1 and 2, from point A to
point B.
Axis 2 movement
Axis 1 movement
F: Specified interpolation feeding speed
Fx: Interpolation feeding speed based on expansion of F to axis 1
Fy: Interpolation feeding speed based on expansion of F to axis 2
Ta: Interpolation acceleration time
Td: Interpolation deceleration time
If the amount of movement along the path is given by L and amounts of movement of axes 1
and 2 by Lx and Ly, Fx and Fy can be expressed by the formula below:
Fx =
Fy =
speed movement, or decelerating, is not the output of the independent status of the axis, but the
status of the path.
Accordingly, all interpolation axes have the same status during interpolation operation.
The status of each axis during interpolation operation, interpolation axis accelerating, constant-
