Input/Output Of Machine Parameters; Entry Format; Appendix - HEIDENHAIN TNC 415 Technical Manual

2 Input/output of machine parameters

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 pre-set to RS-232-C format and FE1
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 analogue voltage in volts. In the TNC 415B and TNC 425,
values are entered and stored to exactly 0.0001 mm (or °). With the TNC 407, TNC 415F and
TNC 425E you can enter to 0.0001 mm (or °), but the entry value is rounded to 0.001 mm (or °).
You can add a written comment to your entry by placing a semicolon ";" behind the numerical entry,
followed by your comment.
The input values can be entered in decimal, binary (%) or hexadecimal ($) format.
There are machine parameters with which individual functions are activated bit-coded. Binary entry
(%) is recommended for these machine parameters. The hexadecimal format ($) may be advisable
for other machine parameters.
Example:
Disabling file types with machine parameter MP7224.0.
Bit 0 HEIDENHAIN programs
Bit 1 DIN/ISO programs
Bit 2 Tool tables
Bit 3 Datum tables
Bit 4 Pallet tables
Bit 5 Text files
The datum tables, pallet tables and text files are to be disabled.
Input value for MP7224.0 =
Binary %111 000
Hexadecimal $ 38
3 4
Decimal 56 (2 + 2 + 2
With software types 243 05, 259 96, 243 07 and 243 02 only the decimal format is possible for the
machine parameters. The corresponding decimal input value must be computed for bit-coded
entries. You will find a "Power of 2" table in the chapter entitled "Appendix".
