486 Fieldbus control through a fieldbus adapter
Actual values
Actual values are 16-bit words containing information on the operation of the drive.
The types of the monitored signals are selected by parameters
50.07
FBA A actual 1
type
and
50.08
FBA A actual 2 type
.
Debugging the network words
If parameter
50.12
FBA A debug mode
is set to
Fast
the actual values sent to the
fieldbus are displayed by
50.17
FBA A actual value 1
and
50.18
FBA A actual value
2
.
Scaling of actual values
Note:
The scalings described below are for the ABB Drives communication profile.
Fieldbus-specific communication profiles may use different scalings. For more
information, see the manual of the fieldbus adapter.
The actual values are scaled as defined by parameters
46.01
…
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
.
