2.3. Feedback Connector
The Feedback connector (a 25-pin, D-style connector) has inputs for an encoder, limit switches, Hall-effect
devices, motor over-temperature device, 5 V encoder and limit power, and optional brake connections. The
connector pin assignment is shown in
with detailed connection information in the following
sections.
