Fieldbus control through the embedded fieldbus interface (EFB) 355
The new settings will take effect when the drive is powered up the next time, or when
they are validated by parameter 58.06 Communication control (Refresh settings).
Setting the drive control parameters
After the embedded fieldbus interface has been set up, check and adjust the drive
control parameters listed in the table below. The Setting for fieldbus control column
gives the value or values to use when the embedded fieldbus signal is the desired
source or destination for that particular drive control signal. The
Function/Information column gives a description of the parameter.
