Data Storage Parameters; Parameter Checksum Calculation - ABB ACS280 Firmware Manual

84 Program features
use digital inputs to switch between user parameter sets. To change a user
parameter set, the drive has to be stopped.
A user parameter set contains all editable values in parameter groups 10...99
except Data storage parameters (
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.

Data storage parameters


Twelve (eight 32-bit, four 16-bit) parameters are reserved for data storage.
These parameters are unconnected by default and can be used for linking,
testing and commissioning purposes. They can be written to and read from
using other parameters' source or target selections.

Parameter checksum calculation

Parameter checksums A and B can be calculated from a set of parameters to
monitor changes in the drive configuration. The parameter sets are different for
A and B. Each of the calculated checksum is compared to corresponding
reference checksum. If a mismatch occurs, the drive generates an event (a pure
event, warning or fault). The calculated checksum can be set as the new
reference checksum.
The set of parameters for checksum A does not include fieldbus settings
parameters.
The parameters included in the checksum A calculation are user editable
parameters in parameter groups 10, 15, 19, 20, 21, 22, 23, 24, 25, 28, 30, 31, 32, 35,
36, 37, 40, 45, 46, 95, 96, 97, 98, and 99.
