2.18 Buffer Correction
I - 107
(1) Buffer correction mode will not be applied in the following cases.
(a) Machining program for buffer corrections is in edit lock or program display lock state.
(b) Data protection key 3 is enabled.
(c) Machining program for the device in write-protection state
(d) Machining program in read-only state
(e) During the compound type fixed cycle, the tool center point control or executing the machine tool builder macro
program
(2) Starting and ending buffer corrections
(a) If automatic operation is started or there is no next command data, the buffer correction mode is not entered
even if the menu key is pressed.
(b) To stop or to cancel the buffer corrections, press the menu [Close] again, or press the key.
(c) If another menu key, etc., is pressed before pressing the [INPUT] key, the corrected buffer contents return to
the original data.
(d) If changing to another screen or resetting the NC during buffer correction, the buffer correction is canceled. In
this case, the corrected contents are not saved, and the buffer correction mode ends.
(3) Display data during buffer correction
(a) The key operations used for corrections in the buffer correction mode are the same as the operations when
editing a program. Up to 16 blocks can be displayed. Even when a block is displayed over several lines, all 16
blocks can be displayed by scrolling the buffer correction area.
(b) Number of characters in one block is max. 256. If exceeds 256 characters, the block will be split into two.
(c) Up to 4096 characters can be edited with buffer corrections.
(4) Operations during buffer correction
(a) If there is no ";" (EOB) at the data in the last block corrected when the [INPUT] key is pressed, it is added
automatically.
(b) When the buffer correction mode is entered, the last block displayed in the buffer correction area may not fit in
if the block is long, etc.
To correct this type of block, take care to the following points.
-
If a ";" (EOB) is added to the end of the displayed data, the section following the incomplete display
becomes another block. If ";" (EOB) is not added, the following section stays the same, and is handled as
the continuation of the displayed section.
- If one block is deleted by pressing the [C.B] key, the block is deleted up to the section following the
incomplete display (up to the ";").
(c) Operation cannot be started during buffer correction. An alarm occurs.
(d) If NC is reset during buffer correction, buffer correction mode will be canceled, although buffer correction
window is left opened. At this time, editing operation is not possible. Close the correction window.
(e) Buffer correction writing is not interrupted by NC reset.
(f)
The operation message "Can't write into file" appears at any attempt of the buffer mode correction to write into
the program being operated or checked, which had stopped when the buffer correction mode started.
