SAVE KINEMATICS (Cycle 450, DIN/ISO: G450, option)

Notes on data management

The TNC stores the saved data in the file TNC:\table\DATA450.KD.
This file can be backed up on an external PC with TNCREMO, for
example. If the file is deleted, the stored data are removed, too.
If the data in the file are changed manually, the data records can
become corrupted so that they cannot be used anymore.
If the TNC:\table\DATA450.KD file does not exist,
it is generated automatically when Cycle 450 is
executed.
Make sure that you delete empty files with the name
TNC:\table\DATA450.KD, if any, before starting Cycle
450. If there is an empty storage table (TNC:\table
\DATA450.KD) that does not contain any lines yet,
an error message will be displayed upon starting to
run Cycle 450. In this case, delete the empty storage
table and call the cycle again.
Do not change stored data manually.
Make a backup of the TNC:\table\DATA450.KD file
so that you can restore the file, if necessary (e.g. if
the data medium is damaged).
