Preventing Electrical Noise
Electromagnetic interference (EMI), commonly called electrical noise, can reduce motor
performance. Effective techniques to counter EMI include filtering the AC power, using
shielded cables, shielding 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.
•
Do not route the single motor cable over the vent openings on servo drives.
•
Ground all equipment by 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.
See System Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001 , for additional information on reducing EMI.
Install the Motor
Motor installation must comply with all local regulations and use of equipment and installation
practices that promote safety and electromagnetic compatibility:
•
All motors include a mounting pilot for aligning the motor on a machine.
•
Preferred fasteners are stainless steel.
ATTENTION: Unmounted motors, disconnected mechanical couplings, loose shaft keys, and
disconnected cables are dangerous if power is applied.
Verify that disassembled equipment is identified (tagged-out) and access to electrical power is
restricted (locked-out).
Before applying power to the motor, remove the shaft key and other mechanical couplings that
could be thrown from the shaft.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
