Fieldbus control through a fieldbus adapter 253
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 145).
Contents of the fieldbus Control word
The upper case boldface text refers to the states shown in the state diagram (page
256).
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).
