Expert Servo Drive Repair

Upon receiving your servo drive, our technicians perform a comprehensive visual inspection, looking for signs of physical damage, overheating, or component stress. The drive is then carefully disassembled and thoroughly cleaned to remove contaminants, ensuring accurate diagnostics.

Using advanced diagnostic tools like oscilloscopes, signature analyzers, component testers, and manufacturer-specific software, we test all critical sections of the drive. Common failure points such as the power supply section (capacitors, rectifiers, IGBTs/MOSFETs), control board, communication ports, and feedback circuits (encoder/resolver inputs) are meticulously checked for proper operation and component tolerances.

Faulty components identified during diagnosis are expertly replaced with high-quality, genuine or equivalent parts using professional soldering and rework techniques. We also proactively replace components known to have high failure rates in specific drive models to improve reliability.

After repair, each servo drive undergoes rigorous testing. This includes powering up the drive, checking power supply voltages, verifying communication, and performing full functional load testing using a compatible servo motor and test stand (dynamometer where applicable). We check output waveforms and performance against OEM specifications before the unit is final cleaned, reassembled, and securely packaged for return, complete with our comprehensive warranty.
