Main and Auxiliary Feedback Combinations
The Main Feedback is always used in motion control devices, whereas the Auxiliary Feedback is
often, but not always used. The Auxiliary Feedback connector on the Eagle HV, Feedback B, has
two ports, Port B1 and Port B2. When used in combination with the Main Feedback port,
Feedback A, these ports can be set, by the software, as follows:
Feedback A
Feedback B Ports B1 and B2
