Issue:Parameter FbS (feedback scale factor)
Product Line:
ATV31 and ATV312
Environment:
All models and serial numbers
Cause:
None
Resolution:
The parameter FbS is a parameter that can be used to scale the reference according to the range of the feedback sensor.
Example: Regulating pressure
PI reference range of process, 0-50 psi (0-100%)
Range of pressure sensor, 0-100 psi
FbS = Max sensor range / Max process range
FbS = 100/50 = 2
