Fieldbus adapter
Actual value
As described earlier in Control interface , Actual Values are words containing drive
values.
Actual value scaling
The scaling of the integers sent to the fieldbus as Actual Values depends on the
resolution of the selected drive parameter. Except as noted for Data Words 5 and 6
below, scale the feedback integer using the resolution listed for the parameter in the
ACH580 HVAC control program firmware manual (3AXD50000027537). For
example:
Data words 5 and 6 are scaled as follows:
Actual value mapping
See the user’s manual supplied with the FBA module.
Feedback Integer Scaling (Feedback Integer) / (Scaling) = Scaled Value
100 (example: 12.11 AI1 actual
feedback)
1000 = 1 unit 100 / 1000 = 0.1 mA
10 10 = 1% 10 / 10 = 1%
