Setting Up The Communication Between Dsu And Inverter Unit - ABB ACS880 Firmware Manual

196 Fieldbus control through a fieldbus adapter
Setting up the communication between DSU and inverter
unit
Connect the fiber optic cables between the DDCS communication port of the
inverter unit (parameter 60.71 INU-LSU communication port) and the DDCS
controller port of the DSU (parameter
In ACS880-07 drives, setting the DSU parameter
Yes automatically sets the following DSU parameters to their right values:
DSU parameter
120.01 Ext1 commands
120.02 Ext1 start trigger
120.12 Run enable 1
160.58 DDCS controller comm loss time

In the diode supply unit, data transmitted from the diode supply unit is defined with
parameters 161.51 Data set 11 data 1 selection...161.74 Data set 25 data 3
Data is received using parameters
set 24 data 3 selection.
In the inverter unit, data transmitted to the diode supply unit is defined with
parameters 61.151...61.186. Data is received using parameters 62.151...62.174.
With the settings above, the inverter unit controls the diode supply unit. In other
words, the diode supply unit receives the Control word from the inverter unit and
transmits the Status word to the inverter unit.
Note: The control program still requires the Run enable command from digital input
DI2 (by default) which is normally wired to the DSU door switch.
