Feedback and Control Assemblies
The Drum HV (High Voltage) 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.
6.
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.
7.
Use only a D-Sub connector with a metal housing.
8.
Ideally, solder the drain wire to the connector body as shown in Figure 10.
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.
9.
On the motor side connections, ground the shield to the motor chassis.
10.
On controller side connections, follow the controller manufacturer’s recommendations
concerning the shield.
