2.3. Motor Feedback Connections (J207)
The motor feedback connector (a 25-pin, D-style connector) has inputs for an encoder, limit switches, Hall-
effect devices, motor over-temperature device, 5 Volt encoder and limit power, and optional brake
connection. The connector pin assignment is shown below with detailed connection information in the
following sections.
