Feedback and Control Cable Assemblies

The Ocarina Evaluation Board features easy-to-use D-sub type connections for all Control and
Feedback cables. Below are instructions and diagrams describing how to assemble those
cables.

ƒ

Use 24, 26 or 28 AWG twisted-pair shielded cables (24 AWG cable is recommended).
For best results, the shield should have aluminum foil covered by copper braid.

ƒ

Use only a D-sub connector with a metal housing.

ƒ

Attach the braid shield tightly to the metal housing of the D-type connector.

ƒ

On the motor side connections, ground the shield to the motor chassis.

ƒ

On controller side connections, follow the controller manufacturer’s
recommendations concerning the shield.
