Issue:
Some parameters reset on my ATV212 drive when I cycle power.

Product line:
ATV212 series drives

Environment:
ATV212 series drives equipped with Lonworks card VW3A21212

Cause:
Information unavailable in current literature.

Resolution:
6 parameters are stored in the Lonworks card.   At each power cycle, the Lonworks card will overwrite these six registers in the drive, with the values stored in the Lonworks card, even if the Lonworks network is not being used.  If the card is installed in the drive, these parameter will be overwritten.   In order to set the parameters, you must write them to the Lonworks card.
