2.2.1 Correcting the Buffer
(1) Outline
During automatic operation (memory or tape mode) 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.

(2) Details
(a) 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.
(b) During memory or MDI operation, not only the displayed buffer data but also the memory and
MDI contents are corrected with the buffer corrections.
(c) If an error occurs in the preread block, the block in which the error occurred can be corrected.
(d) During IC card operation or tape operation, only the displayed buffer data can be corrected.
The IC card and tape contents cannot be changed.
(Note) The buffers on the second and third pages of the COORDINATE screen cannot be
corrected.
