3.4.1 Wiring the Maestro
Once the Maestro 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
Maestro.
Follow these instructions to ensure safe and proper wiring:
ƒ Use twisted pair shielded cables for 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.
ƒ Keep all wires and cables as short as possible.
ƒ Ensure that in normal operating conditions, the shielded wires and drain carry no current.
The only time these conductors carry current is under abnormal conditions, when
electrical equipment has become a potential shock or fire hazard while conducting
external EMI interferences directly to ground, in order to prevent them from affecting the
drive. Failing to meet this requirement can result in drive/controller/host failure.
ƒ After completing the wiring, carefully inspect all wires to ensure tightness, good solder
joints and general safety.
The following connectors are used for wiring the Maestro.
