Fieldbus adapter
PID Control setpoint source
Using the following settings to select the fieldbus as the setpoint source for PID
loops:
Communication fault
When using fieldbus control, specify the drive’s action if serial communication is lost.
Feedback from the drive – FBA
Inputs to the controller (drive outputs) have pre-defined meanings established by the
protocol. This feedback does not require drive configuration. The following table lists
a sample of feedback data. For a complete listing, see all parameters listed in
section Complete parameter descriptions on page 102.
Scaling
To scale the drive parameter values see the following sections, as appropriate:
Actual Value scaling on page 249 (ABB Drives profile technical data)
Actual Value scaling on page 251 (Generic profile technical data).
