Parameter data

What can I parameterize?
You can parameterize the following data storage areas:
S Machine data (MD)
S Increment sizes (SM)
S Tool offset data (TO)
S Traversing programs (NC)
S User data (user data blocks)
This data is stored in data blocks (DBs) within the numerical range 1001 to 1239
(not including user data).
The MD, SM, TO and NC data blocks are transferred to the FM 353 and reside in
memory there.
Parameterization of SM, TO and NC may be omitted if the associated functions are
not used.
The user data block must be stored in the CPU. Only then can it be filled with data
online (see Chapter 6).
Parameterization data (except for user data) can also be created, edited and saved
offline on the PG.
Data blocks (DB) of the FM 353
Table 5-1 gives you an overview of the data blocks in the FM 353 and their mean-
ing.

Machine data serves to adapt the FM 353 to the user's own specific ap-
plication. Parameterization with machine data is essential in order for the
FM's functions to be activated. The parameterized DB-MD should be
loaded to the FM. As it is written to the FM 353, the DB-MD is checked
for the input limits of the individual values and their interdependencies. It
is then stored only if all values are allowed. Otherwise data error mes-
sages are displayed by way of the MPI. A defective DB will not be re-
tained when the power is turned off.
The machine data can then be activated by way of "Activate machine
data" or by switching the equipment on and off.
