9.6 Checking and changing Q parameters
Procedure
You can check Q parameters in all operating modes (when writing,
testing and running programs) and also edit them.
If you are in a program run, interrupt it if required (for example,
by pressing the machine STOP button and the
INTERNAL STOP
soft key). If you are in a test run, interrupt it.
To call the Q parameter functions, press the Q
INFO soft key or the Q key
The TNC lists all parameters and their current
values. Use the arrow keys or the
GOTO key to
select the desired parameter.
If you would like to change the value, press the
EDIT CURRENT FIELD soft key, enter the new
value, and confirm with the
ENT key.
To leave the value unchanged, press the PRESENT
VALUE soft key or end the dialog with the
END
key.
The parameters used by the TNC internally or in
cycles are provided with comments.
If you want to check or edit local, global or string
parameters, press the
SHOW PARAMETERS q QL
QR qs soft key. The TNC then displays the specific
parameter type. The functions previously described
also apply.
