Miscellaneous
￭ 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 10.3 and 10.4
• I/O extension module settings (groups 14…16)
•
fieldbus communication enable parameters (50.1 and 50.31)
• other fieldbus communication settings (groups 51…56 and 58)
• encoder configuration settings (groups 92…93),
•
some hardware settings in parameter group 95, 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.
Settings and diagnostics
Parameters: 10.3 DI force selection (page 175), 10.4 DI force data (page 175), 50.1 FBA
A enable (page 415), 50.31 FBA B enable (page 419), and 96.10 User set
status (page 511)…96.13 User set I/O mode in2 (page 512).
Parameter group: 95 HW configuration (page 499).
Events: 64B2 User set fault (page 552).
￭ 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
