3.4.4. Feedback and Control Cable Assemblies
The Tuba 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 Tuba, should be assembled in this way.
3.4.5. Main Feedback Cable (Feedback A)
The main feedback cable is used to transfer feedback data from the motor to the drive.
The Tuba accepts the following as a main feedback mechanism:
• Incremental encoder only
• Incremental encoder with digital Hall sensors
• Digital Hall sensors only
• Interpolated Analog (Sine/Cosine) encoder (option)
• Resolver (option)
• Tachometer and Potentiometer
• Absolute encoder
Metal housing
Make sure that the braid shield is in tight
contact with the metal housing
