Response to overstore

Before the start, on the SINUMERIK operator interface, the following functions:

• NC START of a part program

• NC START to resume an interrupted part program

the auxiliary functions that are output at the start can be changed by the "Overstore"

Possible applications include:

• Addition of auxiliary functions after block search

• Restoring the initial state to position a part program

Types of auxiliary functions that can be overstored

The following types of auxiliary functions can be overstored:

• M (special function)

• S (spindle speed)

• T (tool number)

• H (aux. function)

• D (tool offset number)

• DL (additive tool offset)

Duration of validity

An overstored auxiliary function, e.g. M3 (spindle right), is valid until it is overwritten by

another auxiliary function from the same auxiliary function group, by additional overstoring or

by programming in a part program block.
