Data storage parameters
Twenty-four (sixteen 32-bit, eight 16-bit) parameters are reserved for data storage.
These parameters are unconnected by default and can be used for eg. linking, testing
and commissioning purposes. They can be written to and read from using other
parameters’ source or target selections.
Note that only 32-bit floating point (type
) parameters can be selected as the
source of another parameter value. In other words, parameters
can be
used as value sources of other parameters while
cannot.
To use a 16-bit integer (received in DDCS data sets) as the source of another
parameter, write the value into one of the
type storage parameters
(
). Select the storage parameter as the source, and define a suitable
scaling method between the 16-bit and 32-bit values in parameters

Reduced run function
A “reduced run” function is available for inverter units consisting of parallel-connected
inverter modules. The function makes it possible to continue operation with limited
current even if one (or more) module is out of service, for example, because of
maintenance work. In principle, reduced run is possible with only one module, but the
physical requirements of operating the motor still apply; for example, the modules
remaining in use must be able to provide the motor with enough magnetizing current.
Activation of the reduced run function
Note:
For cabinet-built drives, the wiring accessories and the air baffle needed during
the procedure are available from ABB, and are included in the delivery.
WARNING!
Follow the safety instructions provided for the drive or
inverter unit in question.
