5. Attach all power, feedback, and brake cables after the motor is
mounted.
A. Use a drip loop in each cable to keep liquids flowing away from the
connectors.
B. Use Electromagnetic Compatibility (EMC) techniques to reduce
Electromagnetic Interference (EMI), commonly called noise. Noise
adversely impacts 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.
– Filter AC power by using isolated AC power transformers or properly
installed AC line filters.
– 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.
– Ground all equipment using a single-point parallel ground system that
employs ground bus bars or large straps.
Refer to System Design for Control of Electrical Noise
(GMC-SG001x-EN-P) for information on additional electrical noise
reduction techniques.
6. If necessary, home the drive and motor system prior to use. Refer to
your drive instructions for procedures on when and how to do this.
IMPORTANT
Ensure that proper polarity is maintained when wiring a
brake connector.
The holding brake is designed to hold the motor shaft at
0 rpm and to release when power is applied - it is not
intended to stop motor rotation. Reversing the brake
polarity could cause the brake to be applied while the
motor is running. The section Holding Brake beginning
on page 27 provides information on the electrical
requirements for a brake motor.
Failure to observe proper polarity could result in damage
to the motor and its components.
