The Cornet has 10 connectors.
1.13.1. Wiring the Cornet
Once the Cornet is mounted, you are ready to wire the device. Proper wiring, grounding and
shielding are essential for ensuring safe, immune and optimal servo performance of the Cornet.
Caution:
Follow these instructions to ensure safe and proper wiring:
eee.
Use twisted pair shielded cables for control, feedback and communication connections.
For best results, the cable should have an aluminum foil shield covered by copper
braid, and should contain a drain wire.
The drain wire is a non-insulated wire that is in contact with parts of the cable, usually
the shield. It is used to terminate the shield and as a grounding connection.
fff.
The impedance of the wire must be as low as possible. The size of the wire must be
thicker than actually required by the carrying current. A 24, 26 or 28 AWG wire for
control and feedback cables is satisfactory although 24 AWG is recommended.
ggg.
Use shielded wires for motor connections as well. If the wires are long, ensure that the
capacitance between the wires is not too high: C < 30 nF is satisfactory for most
applications.
hhh.
Keep all wires and cables as short as possible.
iii.
Keep the motor wires as far away as possible from the feedback, control and
communication cables.
