Fieldbus Control Of The Line-Side Converter; Control Block Diagram - ABB ACS800 Hardware Manual

Fieldbus control of the line-side converter

Fieldbus control of the line-side converter can only be performed via the motor-side
converter RMIO board. The control signal dataset receive and actual signal dataset
transmit addresses are shown in section

Control block diagram

The figure below shows the parameters for DC and reactive power reference
selection of the line-side converter control program. The AMC table contains actual
values and parameters of the line-side converter. The control and actual signal
interchange between the line-side and motor-side converters is also shown.
