2.2.3 Correcting the buffer
(1) Outline
During automatic operation or MDI operation, a block stop can be applied, and the next command
can be corrected or changed.
When a program error occurs, the block in which the error occurred can be corrected without
resetting the NC, and operation can be continued.
(Note)
When running a machining program from the external memory, even if the buffer is
corrected, the revisions are not reflected on the original program.

Buffer correction
(2) Details
1) The next command can be corrected in the following two cases.
• When single block stop is applied, and there is a machining program containing a next
command to be corrected.
• During automatic operation, there is an error (program error) in the next command's
machining program, and the program is stopped.
2) During memory or MDI operation, not only the displayed buffer data but also the memory and
MDI contents are corrected with the buffer corrections. (The corrected data is reflected.)
3) Several blocks following the next command can be corrected simultaneously. (Note that this is
limited to the range displayed on the screen.)
4) If an "In preread block" error occurs, the block in which the error occurred can be corrected.
