8.9 Other Functions
Other functions include the "skip function", "M code output function", "teaching function", "command in-position function",
"acceleration/deceleration processing function", "deceleration start flag function", "speed control 10  multiplier setting for
degree axis function" and "operation setting for incompletion of home position return function".
Each function is executed by parameter setting or program creation and writing.
Skip function
The "skip function" is used to stop (deceleration stop) the control of the positioning data being executed at the time of the skip
signal input, and execute the next positioning data.
A skip is executed by a skip command ([Cd.37] Skip command) or external command signal.
The "skip function" can be used during control in which positioning data is used.
Relation between the skip function and various controls
The following table shows the relation between the "skip function" and various controls.
