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.
