3.5. SAVING
AND
RESETTING
PARAMETERS
The drive has a permanent memory (EEPROM) where parameters are stored. When the drive is switched
on, the drive transfers the parameters from the user permanent memory (EEPROM) to the working memory
(RAM). All the parameter changes are stored in the working memory (RAM); to save these changes in the
user permanent memory (EEPROM), activate the connection (
c43
=1).
If there is an EEPROM alarm (
A2
=H), it means that permanent values can not be read from the EEPROM; it
is necessary to reset the system: reset the default parameters (
c41
=1), and then save them in the user
permanent EEPROM memory (
c43
=1), overwriting the wrong parameters.
To return to the initial parameters in the permanent memory (EEPROM) after the changes in the working
memory (RAM) have been made, without switching off and on again, just activate connection
c42
(
c42
=1).
These procedures are explained below :

N.B. As the default parameters are standard parameters which are certainly different from the customised
parameters, it is important to copy the parameters of the user permanent memory carefully after the
installation for each drive, so that, if necessary, they can be copied in a spare drive, or if the memory
is resetted with the default parameters.

DESCRIPTION OF FONDAMENTAL DATA
In the following are described the parameters, the connections and the minimum displaying magnitudes
necessary for the initial function of the drive. To have the first general vision of all the data prepared for the
customer it’s necessary to read the paragraph 9 of the manual user.
