Checking and changing Q parameters

Procedure
You can check Q parameters in all operating modes, and also edit
them.
If needed, interrupt the program run (e.g., by pressing the
NC STOP key and the INTERNAL STOP soft key), or stop the test
run
To call the Q parameter functions, press the
Q INFO soft key or the Q key
The control lists all of the parameters and their
corresponding current values.
Use the arrow keys or the GOTO key to select the
desired parameter.
If you want to change the value, then press the
EDIT CURRENT FIELD soft key, enter the new
value, and confirm with the ENT key
If you want to leave the value unchanged, then
press the PRESENT VALUE soft key or close the
dialog with the END key
If you want to check or edit local, global or string
parameters, press the SHOW PARAMETERS Q QL QR QS
soft key. The control then displays the specific parameter
type. The functions previously described also apply.
While the control is executing an NC program, you cannot
edit the variables using the Q parameter list window.
Changes are only possible while a program run has been
interrupted or aborted.
This status is reached after an NC block has been
executed, for example in the Program run, single block
mode
The following Q and QS parameters cannot be edited in
the Q parameter list window:
Parameters with numbers in the range from 100
to 199, because there might be interferences with
special functions in the control.
Parameters with numbers in the range from 1200
to 1399, because there might be interferences with
machine manufacturer-specific functions.
All of the parameters with displayed comments are used
by the control within cycles or as transfer parameters.
