Dealing with Servo Drive Contamination

Servo drive contamination is a problem with almost every piece of equipment that comes into Motor Systems for repair. This is especially true around this time of year.

What Causes Servo Drive Contamination?

Summer’s higher indoor temperatures and humidity are a natural catalyst for oil, dust and chemical contamination, helping wreak havoc on a servo drive’s circuitry and cooling system. These unwanted substances can cause tracks corrosion and components damage, which can be a source of intermittent problems.

While some damaged components can be replaced, multiple damaged tracks can render a circuit board unrepairable. To avoid all of these issues, it is crucial to remove the contaminants from the circuit board.

Motor Systems uses a state-of-the-art cleaning system for this delicate task. The first step is to apply a biodegradable cleaning solution that is safe for electronic components. Following this treatment, the circuit boards are then run through a “burning” process in a temperature-controlled lab oven. Having been rid of any remaining moisture, the drive is now ready for testing.
