2 Input/output of machine parameters
If the machine parameters have not yet been entered into the control (e.g., during commissioning),
the TNC presents the list of machine parameters after performing the memory test. The input values
must now be entered either by hand on the keyboard or through the data interface. The data
interface is activated by pressing EXT. It is pre-set to FE mode. This default setting can be changed
through the MOD functions (see Chapter "Data Interface").
2.1 Entry format
A number is entered for each machine parameter. This value can be, for example, the acceleration in
mm/s
2 of an individual axis, or the analog voltage in volts.
Some machine parameters have multiple functions. The entry values for these machine parameters
are calculated in decimal values according to the function to be activated or they can be entered in
binary or hexadecimal format. This depends on the TNC type.
TNC 406: The input values can be entered in decimal, binary (%) or hexadecimal ($) format.
TNC 306: The input values can be entered in decimal.
Example:
Activating axes with encoders by setting machine parameter MP10:
Bit 0 X axis + 0 = Not active
+ 1 = Active
Bit 1 Y axis + 0 = Not active
+ 2 = Active
Bit 2 Z axis + 0 = Not active
+ 4 = Active
Bit 3 4th Axis + 0 = Not active
+ 8 = Active
Bit 4 5th Axis + 0 = Not active
+ 16 = Active
Example: If you wish to activate axes X, Y and Z, the decimal entry value for MP10 is 1 + 2 + 4=7,
the binary value is % 00111, the hexadecimal value is $ 07.
