NJ-series CPU Unit Motion Control User’s Manual (W507)

Example: Interpolation Velocity and Velocities of Axes for Two-axis Cartesian 
Coordinates

The multi-execution instruction remains in the buffer until the current operation is finished. The buffered
instruction is executed after the operation for the current instruction is normally ended.

Blending for axes groups works in the same way as blending for single-axis operations. The buffered
instruction remains in the buffer until the target position of the current instruction is reached. The buff-
ered instruction is executed after the target position of the current instruction is reached. The axes do
not stop at the target position. The two motions are blended together at the interpolation velocity speci-
fied with the 

BufferMode

 input variable.

The Interpolation Acceleration/Deceleration Over axes group parameter is used to select one of the fol-
lowing operations for when the acceleration/deceleration that is specified in the buffered instruction
would exceed the target position.

Use rapid acceleration/deceleration. (Blending is changed to Buffered.)

Use rapid acceleration/deceleration.

Minor fault stop (Treat blending operation as buffered operation.)
