3.9.1 Entering parameters
If the parameters have to be changed, the service level has to be
opened. Afterwards one of the menu items user parameter or
parameter level has to be opened. If the user parameter was chosen,
the parameter choice for device specific functions (e.g. language) is
displayed.
If the parameter level was chosen, an additional set of parameters has
to be chosen afterwards.
The axis parameters are specific parameters for the respective axis
(e.g. encoder direction).
The device parameters include general parameters of the device (e.g.
input logic).
If a set of parameters is chosen, the choice has to be confirmed with
the -key and the appropriate parameters are displayed.
1. Active parameter level
2. Parameter list
3. Cursor
4. Parameter that does not correspond to the default settings
At the upper left corner, the symbol shows which set of parameter is
displayed.
At the parameter list the available parameters are shown.
The cursor can be moved up with the key. The cursor is used to
select one of the displayed parameters.
A parameter which is different to the default parameter value or got
already changed will be deposited with a blue color.
To change the chosen parameter, confirm the choice with the -key.
Through the confirmation, the parameter value is called and will be
shown at the display.

Depending on the selected parameter, a standard parameter or a
multiple choice parameter is displayed instead of the parameter list.
Additional to the current value of the standard parameter, the
minimum, maximum and default values are displayed
The multiple choice parameter is a selection which can be controlled
with the cursor.
Pressing the key calls the next parameter of the parameter list.
If a standard parameter is chosen, the input mode is activated through
pressing the -key and a cursor appears below the current
parameter value.
Fig. 24 Parameter input
The cursor can be switched to the next decade by pressing the -
key. The chosen decade can be incremented with the -key.
If a negative input is possible, the leading sign can be switched by the
cursor. The leading sign will only be displayed with negative values.
The leading sign decade is the first decade at the left.
To finish the input confirm the inserted value with the -key. The
Value will be saved.
To discard the input value, press the -key. The inserted value will
be deleted and the parameter value will be set on the last saved
value.
If a multiple choice parameter is chosen, the cursor can be moved up
with the -key. Through pressing the -key the current selection
will be saved.

With pressing the -key, the current parameter will be closed and
the parameter list is displayed.
If the parameters are saved through a security code, the user has to
insert the right code before the parameters can be changed. The input
of the code works similar as the input of the standard parameter.
Changes in the parameter setting can result in malfunction, stopping
or failure. Changes to the parameter settings should therefore be
made only by knowledgeable personnel.
