Chapter 12 Control Sub Functions
The details and usage of the "sub functions" added and used in combination with
the main functions are explained in this chapter.
A variety of sub functions are available, including functions specifically for machine
OPR and generally related functions such as control compensation, etc.
More appropriate, finer control can be carried out by using these sub functions.
Each sub function is used together with a main function by creating matching
parameter settings and sequence programs. Read the execution procedures and
settings for each sub function, and set as required.
