4.9 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.
Software option
You require the "Extended operator functions" option for the overstore
function (for 828D).
Precondition
The program to be corrected is in the Stop or Reset mode.
Procedure
1. Open the program in the "AUTO" mode.
2. Press the "Overstore" softkey.
The "Overstore" window opens.
3. Enter the required data and NC block.
