Minimizing Electrical Noise in Actuator Drive Systems

Electrical noise is common in industrial environments.  Erratic movements, random system faults, and communications loss, are just a few of the symptoms.  Proper system design and wiring can minimize electrical noise to the point where it doesn't interfere with system reliability.  For more information check out Tolomatic's Whitepaper:

Minimizing electrical noise in actuator drive systems for maximum reliability and performance 

Electric drives and actuators often need to operate in harsh factory conditions that subject the equipment to dust, moisture, heat and vibration. This same environment will also include electrical noise that can disrupt actuator control signals and cause erratic movements or precipitate complete system failure. By understanding electrical noise, system designers can take steps to minimize this interference and ensure higher reliability and maximum performance from electrical drives and actuators. This paper will discuss the
cause of electrical noise and its effects on communication loss, while also providing tips on how to minimize noise and maximize electric drive system performance.
