Fieldbus Reference Scaling - ABB ACS800 Firmware Manual

Fieldbus reference scaling

With the Generic Drive communication profile active, the speed reference value
received from the fieldbus and the actual speed value received from the drive are
scaled as shown in the table below.
Note: Any correction of the reference (see section
applied before scaling.

* With DTC the filter time of the actual speed value can be adjusted using parameter 34.04.
** Note: The maximum reference value is 163% (that is,163% = 1.63 · value of parameter 99.08/99.07 value).
