Activating The Machine Parameter List; Changing The Input Values - HEIDENHAIN TNC 426 PB/M Technical Manual

4.2.2 Activating the Machine Parameter List

4.2.3 Changing the Input Values

4 – 6
After you have entered all the values for the machine parameters:
7 7 7 7 Exit the machine parameter list by pressing the END key.
Missing or incorrect entries result in error messages from the control that
prompt you to correct your entry. The following errors are displayed:
Input error Meaning
0 No MP number found
1 Invalid MP number
2 No separator (:) found
3 Input value incorrect
4 MP doubly defined
6 MP cannot be stored
If the control does not recognize any errors, it automatically exits the machine
parameter editor and is ready for operation.
If you do not make any entries in the machine parameter list during initial
commissioning and exit the editor with the END key, the TNC generates a
standard machine parameter list (MP NAME). In this list the TNC is defined as
a programming station with the HEIDENHAIN standard colors. In all other
machine parameters a default value is entered.
You can enter more than one machine parameter list in the TNC:
7 7 7 7 Select the lists with the PGM MGT key and the SELECT soft key. The last
selected machine parameter list becomes active when you exit the machine
parameter editor.
A machine parameter list can be changed either with the machine parameter
editor or directly through the PLC. The "List of Machine Parameters" includes
the following symbols:
Symbol Change by / Reaction
CN123 The MP is also accessible through the code number 123.
PLC The MP can be changed by the PLC.
Starting in NC Software 280 476-06, this MP can also be
changed in a running NC program during a strobe output.
RUN The MP can also be changed while a program is running.
RESET Changing the MP results in a reset.
REF The axis must be moved over the reference mark again.
