Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called electrical noise, can reduce
motor performance. Effective techniques to counter EMI include filtering the AC
power, use of shielded cables, separating signal cables from power wiring, and
practicing good grounding techniques.
Follow these guidelines to avoid the effects of EMI:
• Isolate the power transformers or install line filters on all AC input power
lines.
• Physically separate signal cables from motor cabling and power wiring. Do
not route signal cables with motor and power wires, or over the vent
openings of servo drives.
• 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.
Refer to System Design for Control of Electrical Noise Reference Manual,
publication
GMC-RM001
, for additional information on reducing the effects of EMI.
