Fieldbus control through the embedded fieldbus interface (EFB) 555
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
on page
.
Bit
Name
Value STATE/Description
0
OFF1_
CONTROL
1
Proceed to READY TO OPERATE.
0
Stop along currently active deceleration ramp. Proceed to
OFF1 ACTIVE
; proceed to
READY TO SWITCH ON
unless other interlocks (OFF2, OFF3) are active.
1
OFF2_
CONTROL
1
Continue operation (OFF2 inactive).
0
Emergency OFF, coast to stop.

OFF2 ACTIVE
, proceed to
SWITCH-ON
INHIBITED
.
2
OFF3_
CONTROL
1
Continue operation (OFF3 inactive).
0
Emergency stop, stop within time defined by drive
parameter. Proceed to OFF3 ACTIVE; proceed to
SWITCH-ON INHIBITED.
Warning: Ensure that the motor and driven machine can
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.
0
Inhibit operation. Proceed to
OPERATION INHIBITED
.
4
RAMP_OUT_
ZERO
1
Normal operation. Proceed to
RAMP FUNCTION
GENERATOR: OUTPUT ENABLED
.
0

ramps to stop (current and DC voltage limits in force).
5
RAMP_HOLD
1
Enable ramp function.
Proceed to
RAMP FUNCTION GENERATOR:
ACCELERATOR ENABLED
.
0
Halt ramping (Ramp Function Generator output held).
6
RAMP_IN_
ZERO
1
Normal operation. Proceed to
OPERATING
.
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
.
Note:
This bit is effective only if the fieldbus interface is
set as the source for this signal by drive parameters.
