4 Inputting and Outputting a Machining Program
Precautions
Notes related to transferring in general
(1) Depending on the type of file, some data cannot be transferred during automatic operation. Do not transfer during
automatic operation.
(2) When the capacity of the transfer destination is reached during file transfer, only the data transferred up to that point
is registered as a file, and an error will occur.
(3) During input to the NC memory or comparison, if the file format size on the NC memory side differs from the other
side file format size (when the maximum number of registrations differs between the NC memory and the other side),
processing is carried out matched to the smaller size.
(Example 1) If a format size of 200 files is input for a format size of 1000 NC files, 200 files are registered.
(Example 2) If 1000 files are input to the NC that formatted for 200 files, the files up to the 200th file can be regis-
tered and an error message appears. (The remaining files are not registered.)
(4) Do not perform any file operation on the transfer source and destination files during the file transfer. The file may be
damaged with the file operation.
Notes when transferring machining program files
(1) The transfer speed is slower if there are many registrations.
(2) The size of one block of the machining program should be 250 characters or less.
(3) The characters that can be used for the file name and directory path are 1-byte number, 1-byte capital alphabetical
letters, and 1-byte symbols recognized by the system. Note that the following characters cannot be used.
|, /, :, "," (comma), *, ?, ", <, >, a to z (small letters), space
Up to 32 characters are allowed for the file name to create in or transfer to NC memory.
(4) If the file whose name includes lower case alphabet is transferred to NC memory, the lower case letter will be con-
verted into the capital letter.
(5) When the MTB macro and fixed cycle program are input, change the program type with the parameter (#1166 fixpro).
Also, set the device and directory as follows.
Device: Memory, Directory: Program
(6) With machining program created by the MELDAS500 Series or earlier model, "EOB" is registered as "LF". However,
when these programs are stored in the C80 Series NC memory, "EOB" will be converted to "CR LF", and the number
of characters will increase. Thus, when all of the machining programs output from an MELDAS500 Series or earlier
model, having the same specifications as the maximum memory capacity, are stored in the C80 Series NC memory,
the memory capacity may be exceeded.
(7) When the file to be transferred (input) is running or in "program restarting" mode, the operation message "Executing
automatic operation" or "Program restarting" is displayed and file will not be transferred (input).
(8) When "#8936 Delete leading 0" is set to "1", if a file name consisting only of numerical figures is input, "0" at the head
of the file name is deleted to be checked.
However, if the file name is out of the range between 1 and 99999999, the leading "0" is not deleted. This also applies
to MTB macros.
Therefore, for example, while the program "1" is in automatic operation, if a file name to transfer (input) is named
"0001", the operation message "Executing automatic operation" appears, and transfer cannot be carried out.
In the case of fixed cycles, regardless of the setting of "#8936 Delete leading 0", the name of the file to transfer must
be 9 digits, and it must not start from "0". Attempting to transfer a file whose name does not satisfy the conditions
above will cause an error.
(9) If the file to be transferred (input) is targeted for edit lock (edit lock B: 8000 to 9999 or edit lock C: 9000 to 9999), the
operation message "Edit lock B" or "Edit lock C" is displayed, causing a transfer failure.
If "#8936 Delete leading 0" is set to "1" and the program name consisting only of numerical figures is input, "0" at the
head will be deleted and checking will be performed. (Example: If the transferring (inputting) file name is "008000",
the operation message "Edit lock B" appears and it cannot be transferred.)
(10) When the multi-part system program management is valid (#1285 ext21/bit0 =1) and "#1285 ext21/bit2" (Multi-part
system program generation and operation) is set to "1", the file transfer to the device [Memory] from the other device
is executed with the machining programs in only displayed part system. In other cases, the machining programs are
transfered across all part systems in batch.
(11) When the multi-part system program management is valid (#1285 ext21/bit0 =1) and "#1286 ext22/bit5" (Selection
of multi-part system program input/output method) is set to "1", the file transfer from the device [Memory] to the other
device is executed with the machining programs in only displayed part system. In other cases, the machining pro-
grams are transfered across all part systems in batch.
