Notes related to transferring in general
1) Depending on the type of file, some data cannot be transferred during automatic operation. Do
2) When the capacity of the transfer destination is reached during file transfer, only the data
3) During input to the NC memory or comparison, if the file format size on the NC memory side
4) Up to 223 files, including the directory, can be registered in the FLD's root directory.
5) Up to 511 files, including the directory, can be registered in the IC card's root directory.
6) An error will occur if the IC card is not mounted.
Notes when transferring machining program files
1) For the RS-232C, always set feed (Null) at both ends of the "EOR" code at the head and end. If
2) The transfer speed is slower if there are many registrations.
3) The size of one block of the machining program should be 250 characters or less.
4) When using tape, carry out parity V adjustment to improve the reliability of the tape format. Then
5) When the machine manufacturer macro and Fixed cycle program are input, change the
6) With machining program created before the MELDAS500 Series, "EOB" is registered as "LF".
Notes when transferring tool offset data files
1) If an error occurs during offset data transfer, an error message appears on the screen, and the

1) In the same manner as when setting in the Parameter screen, there are parameters validated
2) When a parameter file is transferred to the NC memory, the setting value of the input/output

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.
(Ex. 1) If a format size of 200 files is input for a format size of 1000 NC files, 200 files are
registered.
(Ex. 2) If a format size of1000 files is input for a format size of 200 NC files, the files up to the
200th file are registered and an error message appears. (The remaining files are not
registered.)
(512 files can be registered when volume labels are not used. However, if the "File open error"
occurs when the 512th file is registered, the operation message is not an "File open error" but a
"File entry over".)

program type with the parameter (Fix_P). Also, set in the Input/Output screen as follows.
Device: Memory, Directory: Program
However, when these programs are stored in the MELDAS600 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 NC, having the same
specifications as the maximum memory capacity, are stored in the MELDAS600 Series NC
memory, the memory capacity may be exceeded.
