Program features 87
Backup using the drive control panel includes
• Parameter settings
• User parameter sets.
For detailed instructions for performing the backup/restore, refer to page
DriveStudio documentation.
Limitations
A backup can be done without interfering with drive operation, but restoring a backup
always resets and reboots the control unit, so restore is not possible with the drive
running.
Restoring backup files from one firmware version to another is considered risky, so
the results should be carefully observed and verified when done for the first time. The
parameters and application support are bound to change between firmware versions
and backups are not always compatible with other firmware versions even if restore is
allowed by the backup/restore tool. Before using the backup/restore functions
between different firmware versions, refer to the release notes of each version.
Applications should not be transferred between different firmware versions. Contact
the supplier of the application when it needs to be updated for a new firmware
version.
Parameter restore
Parameters are divided into three different groups that can be restored together or
individually:
• Motor configuration parameters and identification (ID) run results
• Fieldbus adapter and encoder settings
• Other parameters.
For example, retaining the existing ID run results in the drive will make a new ID run
unnecessary.
Restore of individual parameters can fail for the following reasons:
• The restored value does not fall within the minimum and maximum limits of the
drive parameter
• The type of the restored parameter is different from that in the drive
• The restored parameter does not exist in the drive (often the case when restoring
the parameters of a new firmware version to a drive with an older version)
• The backup does not contain a value for the drive parameter (often the case when
restoring the parameters of an old firmware version to a drive with a newer
version).
In these cases, the parameter is not restored; the backup/restore tool will warn the
user and offer a possibility to set the parameter manually.
