STATE/DescriptionValueNameBit
Proceed to READY TO OPERATE.1Off1 control0
Stop along currently active deceleration ramp. Proceed
to OFF1 ACTIVE; proceed to READY TO SWITCH ON
unless other interlocks (OFF2, OFF3) are active.
0
Continue operation (OFF2 inactive).1Off2 control1
Emergency OFF, coast to a stop.0
Proceed to OFF2 ACTIVE, proceed to SWITCH-ON IN-
HIBITED.
Continue operation (OFF3 inactive).1Off3 control2
Emergency stop, stop within time defined by drive
parameter.
0
Proceed to OFF3 ACTIVE; proceed to SWITCH-ON IN-
HIBITED.
WARNING!
Ensure motor and driven machine can be stopped
using this stop mode.
Proceed to OPERATION ENABLED.1Run3
Note: Run enable signal must be active. If the drive is
set to receive the Run enable signal from the fieldbus,
this bit activates the signal. See also parameters 6.18
Start inhibit status word and 6.25 Drive inhibit status
word 2.
Inhibit operation. Proceed to OPERATION INHIBITED.0
Normal operation. Proceed to RAMP FUNCTION GEN-
ERATOR: OUTPUT ENABLED.
1Ramp out zero4
Force Ramp function generator output to zero. The
drive will immediately decelerate to zero speed (ob-
serving the torque limits).

Enable ramp function.1Ramp hold5
Proceed to RAMP FUNCTION GENERATOR: ACCELER-
ATOR ENABLED.
Halt ramping (Ramp Function Generator output held).0
Normal operation. Proceed to OPERATING.1Ramp in zero6
Note: This bit is effective only if the fieldbus interface
is set as the source for this signal by drive parameters.
