Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called noise, may
adversely impact motor performance by inducing stray signals.
Effective techniques to counter EMI include filtering the AC power,
shielding and separating signal carrying lines, and practicing good
grounding techniques.
Effective AC power filtering can be achieved by using isolated AC
power transformers or properly installed AC line filters.
To help avoid EMI:
1. Physically separate signal lines from motor cabling and power
wiring. Do not route signal wires with motor and power wires, or
over the vent openings of servo drives.
2. Ground all equipment using a single-point parallel ground system
that employs ground bus bars or large straps. If necessary, use
additional electrical noise reduction techniques to reduce EMI in
noisy environments.
