User parameter sets
The drive supports 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 user parameter sets.
A user parameter set contains all editable values in parameter groups 10…99 except
• forced I/O values such as parameters 10.03 DI force selection and 10.04 DI force
data
• fieldbus communication enable parameters (50.01 FBA A enable)
• other fieldbus communication settings (groups 51…53 and 58)
• encoder configuration settings (groups 92),
• some hardware settings in parameter group 95 HW configuration, and
• user set selection parameters 96.11…96.13.
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 the drive, the motor ID run needs to
be performed with each motor and the results saved to different user sets. The
appropriate set can then be recalled when the motor is switched.
If no parameter sets have been saved, attempting to load a set will create all sets
from the currently active parameter settings.
Switching between user parameter sets is only possible with the drive stopped.

Parameter checksum calculation
A parameter checksum can be calculated from a user-definable set of parameters to
monitor changes in the drive configuration. The calculated checksum is compared to
1…4 reference checksums; in case of a mismatch, an event (a pure event, warning or
fault) is generated.
By default, the set of parameters included in the calculation contain most parameters
with the exception of
• actual signals
• parameter group 47 Data storage
• parameters that are activated to validate new settings (such as 51.27 and 96.07)
• parameters that are not saved to the flash memory (such as 96.24…96.26)
• parameters that are internally calculated from others (such as 98.09…98.14).
• dynamic parameters (eg. parameters that vary according to hardware), and
• application program parameters.
The default set can be edited using the Drive customizer PC tool.
