8.12 Response to overstore
Overstore
On the SINUMERIK operator interface, before starting 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" function.
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)
• F (feed)
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.
