parameters. To enable protection using motor model parameters or measurement devices set parameter 35.11 and
subsequent parameters through 35.55. To adjust motor class curves (default is class 20), change parameters 35.56 and
35.57.
?
Use the information key ( ) on the drive control panel for more information on setting group 35 parameters. You must set
the drive overload parameters correctly, or motor damage could occur.
Fieldbus communication
To configure the embedded fieldbus communication for Modbus RTU, you must set at least these parameters:
Parameter

Description
Embedded
Selects fieldbus as the source for the start and stop commands when
fieldbus
EXT1 is selected as the active control location.
EFB ref1
Selects a reference received through the embedded fieldbus interface
as speed reference 1. Use this parameter with the vector motor control
mode.
EFB ref1
Selects a reference received through the embedded fieldbus interface
as frequency reference 1. Use this parameter with the frequency motor
control mode.
Modbus RTU
Initializes embedded fieldbus communication.
1 (default)
Node address. There must be no two nodes with the same node
address online.
19.2 kbps (default) Defines the communication speed of the link. Use the same setting as
in the master station.
8 EVEN 1 (default)
Selects the parity and stop bit setting. Use the same setting as in the
master station.
Refresh settings
Validates any changed EFB configuration settings. Use this after
changing any parameters in group 58.
