DRIVE PARAMETER BACKUP MODE
The drive parameter back up mode is used to export the param-
eters from one drive to another. The parameters can be upload-
ed from a VFD to the removable control panel. The control
panel can then be transferred to another drive and the parame-
ters downloaded into memory.
Depending on the motor and application, there are two options
available. The first option is to download all parameters. This
copies both application and motor parameters to the drive from
the control panel. This is recommended when using the same
application for drives of the same size. This can also be used to
create a backup of the parameters group for the drive.
The second option downloads only the application parameters
to the drive. This is recommended when using the same appli-
cation for drives of different sizes. Parameters 9905, 9906,
9907, 9908, 9909, 1605, 1607, 5201, and group 51 parameters
and internal motor parameters are not copied.
