Automatic parameter backup (P6.3.4)

On this page you can activate or inactivate the parameter backup function. Enter the edit mode by pressing
the

Menu button right

. Choose

Yes

or

No

with the

Browser buttons

.


When the Parameter backup function is activated Vacon NX control keypad makes a copy of the para-
meters of the presently used application. Every time a parameter is changed the keypad backup is
automatically updated.

When applications are changed, you will be asked if you wish the parameters of the new application to be
uploaded to the keypad. For this to happen, push the

Enter button

. If you wish to keep the copy of the

parameters of the previously used application saved in the keypad push any other button. Now you will be
able to download these parameters to the drive following the instructions given in chapter 7.3.6.3.

If you want the parameters of the new application to be automatically uploaded to the keypad you have to
do this for the parameters of the new application once on page 6.3.2 as instructed. Otherwise the panel
will always ask for the permission to upload the parameters.

Note: Parameters saved in the parameter settings on page S6.3.1 will be deleted when applications are
changed. If you want to transfer the parameters from one application to another you have to upload them
first to the keypad.

7.3.6.4 Parameter

comparison

In the

Parameter comparison

submenu (S6.4), you can compare the actual parameter values to the

values of your customised parameter sets and those loaded to the control keypad.

The comparison is performed by pushing the

Menu button right

when in the

Compare parameters

submenu

. The actual parameter values are first compared to those of the customised parameter Set1. If no

differences are detected a '0' is displayed on the lowermost line. But if any of the parameter values differ
from those of the Set1 the number of the deviations is displayed together with symbol P (e.g. P1

P5 = five

deviating values). By pressing the

Menu button right

once again you can still enter the pages where you can

see both the actual value and the value it was compared to. In this display, the value on the

Description line

(in the middle) is the default value and the one on the

value line

(lowermost) is the edited value.

Furthermore, you can also edit the actual value with the

Browser buttons

in the

edit mode

that you can

reach by pushing the

Menu button right

once again.

In the same way, you can perform the comparison of the actual values to

Set2

,

Factory Settings

and

Keypad

Set

.
