Fieldbus control through a fieldbus adapter 373
Scaling of actual values
The actual values are scaled as defined by parameters
46.03
and
46.04
; which
scaling is in use depends on the setting of parameters
50.07 FBA A actual 1 type
and
50.08 FBA A actual 2 type
(see page
211
).
 Contents of the fieldbus Control word
The upper case boldface text refers to the states shown in the state diagram
(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 a 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 SWITCH-ON INHIBITED .
WARNING: Ensure motor and driven machine can be
stopped using this stop mode.
3 Run 1 Proceed to OPERATION D .
Note: Run enable signal must be active; see 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 D .
0 Force Ramp function generator output to zero. The drive will
immediately decelerate to zero speed (observing the torque
limits).
