Message Operation
The EE memory function allows three different message requests:
• EE Save saves parameter information from the working memory
or RAM to EEPROM.
• EE Recall retrieves the last saved data from EEPROM and places
it in the working memory or RAM.
• EE Default Initialize clears the RAM and EEPROM and sets all
parameter values to default.
If an error has occurred, word 2 of the response returns a value of
–31998.
