Drive Parameter Backup Mode
The drive parameter back up mode is used to export the
parameters from one drive to another. The parameters can
be uploaded from a VFD to the removable control panel.
The control panel can then be transferred to another drive
and the parameters 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 application for drives of different sizes.
