4.1 General Information
A control must have access to specific machine data (e.g., traverse distances,
acceleration, speeds) before it can execute its programmed instructions. You
define these data in machine parameters. Each machine has its own set of
parameters.
The parameter values are entered in the configuration editor.
The machine parameters are grouped as parameter objects in a tree structure.
They are saved in
parameter files with the extension *.cfg on the drives
TNC:\ , PLC:\ and SYS:\ .
These drives should always be addressed with the system variables %OEM%
( PLC:\ ), %SYS% ( SYS:\ ) and %USR% ( TNC:\ ).
Each parameter object (also called data object or object) has a name that gives
information about the parameters it contains.
Depending on the function, the parameters are differentiated into system-spe-
cific, channel-specific and axis-specific types.
Each object has a “key” for unique identification. The key name can have a
maximum of 18 characters.
Note
You should only make changes to the parameter files by using the configu-
ration editor.
Only in exceptional cases should the *.cfg files be edited directly. Other-
wise, this could possibly lead to faulty syntax, which would prevent the
control from starting up.
