4.6.  Feedbacks 
The Hornet and Bee can receive and process feedback input from diverse types of devices. 
4.6.1.  Feedback Supply Voltage 
The Hornet and Bee have two feedback ports (Main and Auxiliary). The drives supply voltage 
only to the main feedback device. The user must provide a separate power supply for auxiliary 
feedback devices if needed.
