Program features 85
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.
User parameter sets
The drive has four user parameter sets that can be saved to the permanent memory
and recalled using drive parameters. It is also possible to use digital inputs to switch
between different user parameter sets. See the descriptions of parameters
16.09…16.12.
A user parameter set contains all values of parameter groups 10 to 99 (except the
configuration settings for fieldbus adapter communication).
As the motor settings are included in the user parameter sets, make sure the settings
correspond to the motor used in the application before recalling a user set. In an
application where different motors are used with one drive, the motor ID run needs to
be performed with each motor and saved to different user sets. The appropriate set
can then be recalled when the motor is switched.

Data storage parameters
Four 16-bit and four 32-bit parameters are reserved for data storage. These
parameters are unconnected and can be used for linking, testing and commissioning
purposes. They can be written to and read from using other parameters’ pointer
settings.
