4.2 Back Up and Copying Parameter
Settings
Programming data is stored internally in the frequency
converter.
•
The data can be uploaded into the LCP memory
as storage back-up.
•
Once stored in the LCP, the data can be
downloaded back into the frequency converter.
•
Data can also be downloaded into other
frequency converters 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 frequency converter to restore
factory default settings does not change data
stored in the LCP memory.
