Serial Communication – FBA
PID Control Setpoint Source
Using the fieldbus for the PID control setpoint requires:
• Drive parameter values set as defined below.
• Fieldbus controller supplied setpoint value in the appropriate location. (As defined
in
"Analog Output Control" above.)
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
"Parameter Descriptions".
Scaling
To scale the drive parameter values see the "Actual Value Scaling" in the following
sections, as appropriate:
