Robotic Arm Servo Maintenance

Industrial robot arms operate with a servo motor and encoder on each axis. Faults in these servos, encoders or drives degrade the robot precision and repeatability. We repair and calibrate the servo components of your robot arm axes.

Robot Arm Fault Symptoms

• Vibration and position loss on an axis
• Loss of repeatability
• Axis servo alarm and overcurrent
• Encoder / feedback error

Our Robot Servo Repair Process

We repair the axis servo motor, encoder and brake, test the drive and perform zero-point calibration. See our services.

Frequently Asked Questions

The robot vibrates on a certain axis — why?

Usually worn bearings, an encoder fault or a servo/drive failure; the axis is dismantled and tested to find the source.

Can position/repeatability loss be fixed?

Yes. Servo and encoder repair plus calibration restore original precision.

Do you repair the robot on site?

We take the faulty axis components to the lab and provide on-site support for commissioning if needed.

Is the repair warranted?

Yes, delivered under warranty after testing.
