• Fieldbus controller supplied setpoint value in the appropriate location. (As defined
in
"Analog Output Control" above.)
1. BACnet not defined at time of publication.
Communication Fault
When using fieldbus control, specify the drive’s action if serial communication is lost.
Feedback from the Drive – EFB
Pre-defined Feedback
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 input word/point/object
listings in the technical data for the appropriate protocol starting on page 155.
1. BACnet not defined at time of publication.
Note! With Modbus, any parameter can be accessed using the format: 4 followed by
the parameter number.
