.11 Feedback and Control Cable Assemblies
The EVA-WHI/GUI/BEL 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.
 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.
 Use only a D-sub connector with a metal housing.
 Attach the braid shield tightly to the metal housing of the D-type connector.
 On the motor side connections, ground the shield to the motor chassis.
 On controller side connections, follow the controller manufacturer’s
recommendations concerning the shield.

Note: All D-sub type connectors, used with the Evaluation Board, should be assembled
in this way.
.12 Main Feedback
The Main Feedback port is used to transfer feedback data from the motor to the drive.
The Evaluation Board accepts the following as a main feedback mechanism:

Incremental encoder only
 Incremental encoder with digital Hall sensors
 Digital Hall sensors only
 Incremental Analog (Sine/Cosine) encoder (option)
 Resolver (option)
 Tachometer and Potentiometer (option)
Metal Housing
Make sure that the braid shield is in
tight contact with the metal housing
