2 Input/Output of Machine Parameters
To call the machine parameter editor, press the MOD key and select "code number."
Enter the code number 95148 to access the complete set of machine parameters.
The accesses a limited set of the machine parameters. This set of parameters can be safely
entrusted to access by the control user (see User's Manual) The machine parameters that can be
changed with the code number 123 are indicated in the list below with CN 123.
To exit the machine parameter editor, press the END
key.
If the machine parameters have not yet been entered in a HEIDENHAIN contouring control (e.g.,
during commissioning), the TNC presents the list of machine parameters after the memory test.
Now the input values must be entered either by hand on the keyboard or through the data interface.
The data interface is activated by pressing the EXT key. It is preset to RS-232-C format and FE1
mode. This default setting can be changed through the MOD functions (see Chapter "Data
Interface").
A number is entered for each machine parameter. This value can be, for example, the acceleration
in m/s
2
of an individual axis, or the analog voltage in volts.
Some machine parameters have multiple functions. The input values for these machine parameters
are calculated according to the function to be activated.
Up to 16 different functions can be activated/deactivated in one machine parameter with bits 0 to
15. The input value is the sum of the decimal values of the bits representing the desired functions.
