4.2 Backup and Copying Parameter Settings
Programming data is stored internally in the adjustable
frequency drive.
•
The data can be uploaded into the LCP memory
as a storage backup.
•
Once stored in the LCP, the data can be
downloaded back into the adjustable frequency
drive.
•
Data can also be downloaded into other
adjustable frequency drives by connecting the
LCP into those units and downloading the stored
settings. (This is a quick way to program multiple
units with the same settings).
•
Initialization of the adjustable frequency drive to
restore factory default settings does not change
data stored in the LCP memory.
