Important: TB3 (labeled ANALOG OUT) should only be used for drive
applications that do not require a feedback device. If a feedback is
required, the output signal to the drive and its corresponding encoder
feedback should be wired through one of the axis connectors J3, J2, or J1.
A drive application with feedback would typically not use the connector
TB3.
