PARAMETER COPY

The parameters defined by the firmware can be written and read by the four memory areas of the control
board:
a. Flash U20, containing the default factory setting of all parameters.
b. RAM U21, containing the parameters used when the drive is on.
c. Work area of EEPROM U11, where the user parameters may be stored.
d. Backup area of EEPROM U11, where the user parameters may be copied for safety reasons.
We adopted any measure (namely the serial communication for EEPROM U11) to prevent the values
stored for the different parameters from being changed due to disturbance or transients. At the same time,
a set of alarms and warnings will trip and suggest the reader how to retrieve the correct data.
The diagram below contains the sequence of the automatic controls performed when the equipment is
turned on.
Step 3 typically takes place when the drive is turned on. In steps 4 and 5, the parameter original values
may be retrieved following the given instructions. For steps 1 and 2, contact ELETTRONICA SANTERNO.
For a better understanding of the meaning of the different alarms or warnings, please refer to ALARM
PARAMETERS and WARNING PARAMETERS chapters.
