Control Word for the ABB Drives profile

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 State transition diagram for the ABB Drives profile

Value STATE/Description
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 Continue operation (OFF2 inactive).
0 Emergency OFF, coast to stop.
Proceed to OFF2 ACTIVE, proceed to SWITCH-ON
INHIBITED.
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.
1 Proceed to OPERATION D.
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.
1 Normal operation. Proceed to RAMP FUNCTION
GENERATOR: OUTPUT D.
0 Force Ramp Function Generator output to zero. Drive
ramps to stop (current and DC voltage limits in force).
1 ramp function. Proceed to RAMP FUNCTION
GENERATOR: ACCELERATOR D.
0 Halt ramping (Ramp Function Generator output held).
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.
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.
0 Continue normal operation.
