Feedback to the PI regulator can be derived from two different feedback channels.
This flexibility allows the position loop to operate with either a motor based
feedback device that is typically attached to the Feedback 1 channel or a load-side
feedback device that is connected to the Feedback 2 channel. Which feedback
source is used by the loop is governed by the Feedback Mode attribute.
When the Feedback Mode calls for Dual Feedback operation, the position loop
utilizes the Feedback 2 channel and the velocity loop uses the Feedback 1 channel.
Since the two feedback channels may not have the same feedback resolution, it is
necessary to convert position loop output from Feedback 1 units to Feedback 2
