13.3.6 Adjustment of the machine parameters involved
The best adjustment of the backlash peak may require modifying the value of certain
machine parameters. This may be done directly in this window, thus without having
to go to the machine parameter table.
When turning the CNC on, it assumes the new values in the CNC tables and/or in
the drive tables accordingly. When changing these values, the changes are effective
immediately and are assumed by the CNC until the unit is turned off. Once the setup
is completed, the changes must be validated so they can be effective next time the
CNC is turned on.
The parameters may be modified before or during the test.
Selection of the parameters to be displayed
It is possible to interact with up to 11 different machine parameters. Some of these
parameters are always visible, but some may be defined at will. However, the CNC
will only admit the valid parameters for this type of adjustment.

To see the whole list of parameters that may be defined, see section
"13.3.8 Machine parameters that may be modified". When using Fagor Sercos
drives, the drive parameters may also be adjusted.
How to select the parameters
The parameter setting area shows three data columns. The parameters are defined
in the first column. The rest of the fields show the parameter value for each axis.
The list of valid parameters is shown when editing a parameter or pressing [SPACE].
Use the [©][ª] keys to move through the list and [ENTER] to select one of them. Once
selected, the rest of the fields show the parameter value for each axis.
To select the parameters of the drive, simply write their names.
Save the value of the parameters
The new data is assumed by the CNC until the unit is turned off. Once the setup is
completed, the changes must be saved so they can be effective next time the CNC
is turned on.
Use the VALIDATE
softkey to save the data. The CNC saves the new values in the
CNC tables and/or in the drive tables accordingly.
When quitting the circularity test without having saved the parameters, the CNC will
show a message warning about it and will give a chance to save them.
