8.2.8 Linear Interpolation with Skip Function (SKP)

(1) Overview

The Linear Interpolation with Skip Function command (SKP) is an extended command of the Linear Interpola-
tion command (MVS). When the skip input signal is turned ON during axis movement by a SKP command, the
moving axis is decelerated to a stop and the remaining travel distance is cancelled.
A use of a SKP command enables the programming of motion control that can respond to external conditions.
The skip signal is input to the control signal for the MSEE command or the control register of M-EXECUTOR.

Fig. 8.40 Axis Movement by SKP Command

The moving axis decelerates to a stop when the skip input signal is turned ON. The SKP command, however,
remains in effect until the positioning completion signal is turned ON.
