3.7. Feedback and Control Cable Assemblies
The DC Trombone 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.
1.
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.
2.
Use only a D-Sub connector with a metal housing.
3.
Ideally, solder the shield drain wire to the connector body as shown in Figure 12. However,
the shield may also be attached without soldering, as long as the braid shield is in tight
contact with the metal housing of the D-type connector.
4.
On the motor side connections, ground the shield to the motor chassis.
5.
On controller side connections, follow the controller manufacturer’s recommendations
concerning the shield.

Note:
All D-Sub type connectors, used with the DC Trombone, should be assembled in this
way.

The DC Trombone can accept any one of the following devices 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 (option)
•
Potentiometer (option)
•
Absolute Encoder
