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 1-205.
Note: With Modbus, any parameter can be accessed using the format: 4 followed by
the parameter number.
