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