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

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.
Proceed to 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

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
