6.9 Overstore

6.9 Overstore
With overstore, you have the option of executing technological parameters (for example,
auxiliary functions, axis feed, spindle speed, programmable instructions, etc.) before the
program is actually started. The program instructions act as if they are located in a normal part
program. These program instructions are, however, only valid for one program run. The part
program is not permanently changed. When next started, the program will be executed as
originally programmed.
After a block search, the machine can be brought into another state with overstore (e.g. M
function, tool, feed, speed, axis positions etc.), in which the normal part program can be
successfully continued.
Precondition
The program to be corrected is in the Stop or Reset mode.
