7.3.2 Parameter menu (M2)
Parameters are the way of conveying the commands of the user to the inverter. Parameter values
can be edited by entering the
Parameter Menu
from the
Main Menu
when the location indication M2
is visible on the first line of the display. The value editing procedure is presented in Figure 7-1.
Pressing
Menu button right
once takes you to the Parameter Group Menu
(G#)
. Locate the desired
parameter group by using the Browser buttons and press
Menu button right
again to see the group
and its parameters. Use the
Browser buttons
to find the parameter (P#) you want to edit
.
Pressing
Menu button right
takes you to the edit mode. As a sign of this, the parameter value starts to blink.
You can now change the value in two different ways:

Set the desired value with the
Browser buttons
and confirm the change with the
enter
button.
Consequently, the blinking stops and the new value is visible in the value field.

Press Menu button right once more. Now you will be able to edit the value digit by digit. This may
come in handy, when a relatively greater or smaller value than that on the display is desired.
Confirm the change with the
enter button.
The value will not change unless the Enter button is pressed. Pressing
Menu button left
takes
you back to the previous menu.
Several parameters are locked, i.e. cannot be edited, when the drive is in RUN status. If you try to
change the value of such a parameter the text
*Locked*
will appear on the display. The inverter
must be stopped to edit these parameters.
The parameter values can also be locked using the function in menu M6 (see Chapter6.5.2)).
You can return to the Main menu any time by pressing
Menu button left
for 1 to 2 seconds.
The basic application package "All in One+" includes seven applications with different sets of
parameters. You will find the parameter lists in the Application Section of this manual.
Once in the last parameter of a parameter group, you can move directly to the first parameter of that
group by pressing
Browser button up
.
See the diagram for parameter value change procedure on page 67.
Note: You can connect power to the control board by connecting the external power source to the
bidirectional terminal #6 on the OPT-A1 board (see page 55). The external power source can also be
connected to the corresp24V terminal on any option board. This voltage is sufficient for
parameter setting and for keeping the fieldbus active.
