1.13.4. Feedback and Control Cable Assemblies
The Cornet features easy-to-use D-Sub type connections for all Control and Feedback cables.
Instructions and diagrams describing how to assemble those cables are presented below.
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.
Use only a D-Sub connector with a metal housing.
Ideally, solder the drain wire to the connector body as shown in Figure 13.
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.
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 Cornet, should be assembled in this way.
1.13.5. Main Feedback Cable (FEEDBACK A)
The main feedback cable is used to transfer feedback data from the motor to the drive.
The Cornet accepts the following as a main feedback mechanism:
lll.
Incremental encoder only
mmm. Incremental encoder with digital Hall sensors
nnn. Digital Hall sensors only
ooo. Incremental Analog (Sine/Cosine) encoder (option)
ppp. Resolver (option)
qqq. Tachometer and Potentiometer
rrr. Absolute encoder
FEEDBACK A on the front of the Cornet has a 15-pin D-Sub socket. Connect the Main Feedback
cable from the motor to FEEDBACK A using a 15-pin, D-Sub plug with a metal housing. When
assembling the Main Feedback cable, follow the instructions in Section 1.13.4 (Feedback and
Control Cable Assemblies).
