2.2.3. Minimizing Conducted, Radiated, and System Noise

To reduce electrical noise, observe the following motor and input power wiring techniques.
1. Use shielded cable to carry the motor current and tie the shield to earth ground.
2. Use a cable with sufficient insulation. This reduces the capacitive coupling between the leads that, in
turn, reduces the current generated in the shield wire.
3. Provide strong earth ground connections to the amplifier and the motor. Offering electrical noise a low
impedance path to earth ground not only reduces radiated emissions, but also improves system
performance.
4. User connections to the product must be made using shielded cables with metal D-style connectors
and back shells. The shield of the cables must be connected to the metal back shell in order for the
product to conform to the radiated emission standards.
5. The Ensemble LAB is a component designed to be integrated with other electronics. EMC testing must
be conducted on the final product configuration.
6. Ferrite beads or Aerotech's FBF-1 or FBF-2 filter adapters, may be used on the motor leads to reduce
the effects of amplifier EMI/RFI, produced by PWM (pulse width modulation) amplifiers.
