Actual value
As described earlier in
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:
100 (example: 12.11 AI1 actual
feedback)
10
Data words 5 and 6 are scaled as follows:

Scaling (Feedback Integer) / (Scaling) = Scaled Value
1000 = 1 unit 100 / 1000 = 0.1 mA
10 = 1% 10 / 10 = 1%
