Fieldbus control through the embedded fieldbus interface (EFB) 365Setting up the embedded fieldbus interfaceSet the drive up for the embedded fieldbus communication with the parametersshown in the table below. The Setting for fieldbus control column gives either thevalue to use or the default value. The Function/Information column gives adescription of the parameter.Parameter Setting forfieldbus control Function/InformationCOMMUNICATION INITIALIZATION58.01 Protocol enable Modbus RTU Initializes embedded fieldbus communication.EMBEDDED MODBUS CONFIGURATION58.03 Node address 1 (default) Node address. There must be no two nodeswith the same node address online.58.04 Baud rate 19.2 kbps (default) Defines the communication speed of the link.Use the same setting as in the master station.58.05 Parity 8 EVEN 1 (default) Selects the parity and stop bit setting. Use thesame setting as in the master station.58.14 Communicationloss actionFault (default) Defines the action taken when acommunication loss is detected.58.15 Communicationloss modeCw / Ref1 / Ref2(default)Enables/disables communication lossmonitoring and defines the means forresetting the counter of the communicationloss delay.58.16 Communicationloss time3.0 s (default) Defines the timeout limit for thecommunication monitoring.58.17 Transmit delay 0 ms (default) Defines a response delay for the drive.58.25 Control profile ABB Drives(default)Selects the control profile used by the drive.See section Basics of the embedded fieldbusinterface (page 368).58.2658.27EFB ref1 typeEFB ref2 typeSpeed orfrequency (defaultfor 58.26),Transparent,General,Transparent (default for58.27) Speed,FrequencyDefines the types of fieldbus references 1 and2. The scaling for each reference type isdefined by parameters 46.01…46.03. Withthe Speed or frequency setting, the type isselected automatically according to thecurrently active drive control mode.58.2858.29EFB act1 typeEFB act2 typeSpeed orfrequency (defaultfor 58.28),Transparent(default for 58.29),General, Speed,FrequencyDefines the types of actual values 1 and 2.The scaling for each actual value type isdefined by parameters 46.01…46.03. Withthe Speed or frequency setting, the type isselected automatically according to thecurrently active drive control mode.
