Fieldbus control through the embedded fieldbus interface (EFB) 393
The ABB Drives profile
Control Word
The table below shows the contents of the fieldbus Control Word for the ABB Drives
control profile. The embedded fieldbus interface converts this word to the form in
which it is used in the drive. The upper case boldface text refers to the states shown
in

be stopped using this stop mode.
3
INHIBIT_
OPERATION
1
Proceed to
OPERATION ENABLED
.
Note:
Run enable signal must be active; see the drive
documentation. If the drive is set to receive the Run
enable signal from the fieldbus, this bit activates the
signal.

OPERATION INHIBITED
.
4
RAMP_OUT_
ZERO
1
Normal operation. Proceed to
RAMP FUNCTION
GENERATOR: OUTPUT ENABLED
.
0

.
Note:
This bit is effective only if the fieldbus interface is
set as the source for this signal by drive parameters.
0
Force Ramp Function Generator input to zero.
7
RESET
0=>1
Fault reset if an active fault exists. Proceed to
SWITCH-
ON INHIBITED
