Servo Drive and Servo Motor Repair

Servo systems are the heart of machines that need precise positioning; one stopped axis stops the whole machine. We repair the power and control boards of servo drives and diagnose encoder and feedback related faults.

Repair scope

  • Servo drive power stage and control boards
  • Diagnosis of encoder / resolver feedback faults
  • Brake, fan and supply circuits
  • Multi-axis drive modules

Typical symptoms

  • Encoder or feedback error
  • Overcurrent / overload alarm
  • Axis vibrates or cannot hold position
  • Drive does not reach ready state

How we work

  1. 01

    Fault Diagnosis

    Accurate component analysis with VI impedance testers and oscilloscopes.

  2. 02

    Component Repair

    Original part replacement under microscope at BGA/SMD stations.

  3. 03

    Software & Cleaning

    Parameter backup, error-code reset and ultrasonic board washing.

  4. 04

    Testing Under Load

    100% load testing on simulators and motor benches, plus 6-month warranty.

Frequently asked questions

Do I need to send the motor as well?

If the fault appears to come from the encoder or feedback, sending the motor and cable together with the drive lets us pinpoint the source of the fault.

How long does a repair take?

We do a same-day free pre-analysis; after approval most boards are repaired within 2–5 business days, tested under load and delivered.

What does the warranty cover?

We provide a 6-month warranty on all repaired boards after 100% functional testing under load.

Is the pre-analysis paid?

No. Pre-analysis and fault diagnosis are free; the repair decision is entirely yours.

Send us your request

Send the fault description and a photo of the board if available; we will reply with a free same-day pre-analysis.
