5.2.3 Buffer Correction
M720VW
M system
○
L system
○
During automatic operation (including memory, tape, HD, IC card or DS operation) or MDI operation, this
function initiates single block stop and enables the next command to be corrected or changed.
Only memory or HD operation allows the changes with buffer corrections to be updated in the machining
program.
When a program error has occurred, the function enables the block in which the error occurred to be
corrected and operation to be resumed without having to perform NC resetting.
