Siemens servo drive repair in India

We repair Siemens servo drives and motor modules at component level: power stage, DC link, feedback input, control and I/O faults. Every repaired drive is tested with a servo motor under load before dispatch and returned with a printed test report. Send the drive label and the fault number, such as F30001, to get a quote.

Repair turnaround you can plan around

Send a photo of the nameplate first. We confirm whether the motor is repairable, and the quote, the same working day.

Emergency: same day

For a line-down motor, where the fault and parts allow. WhatsApp us before you send it so the bench is kept free.

Urgent: 3 working days

Repair, encoder alignment and test, counted from the day the motor reaches the bench and the quote is approved.

Standard: 7 working days

Full repair, encoder alignment, run test under load and a printed test report.

  • Free repairability check from a nameplate photo
  • Printed test report with every motor
  • Written warranty, terms stated on every quotation
  • Pickup can be arranged; parts that must be imported are quoted with their own timeline

02Failure modes

Common Siemens drive faults

A drive alarm tells you where to look, not always what failed. Overcurrent can be the power stage, the gate drive, the motor or the cable.

  • No power, or a failed power stage
  • DC link and precharge faults
  • Overcurrent and ground-fault trips
  • Encoder and DRIVE-CLiQ feedback faults
  • Control board and power supply faults
  • Cooling fan and overtemperature faults
03Alarm codes

Siemens alarm codes and what to check

The faults below are common SINAMICS S120 power unit faults. Numbers differ on other Siemens series.

F30001: power unit overcurrent

Can be the power stage, the motor or the cable. Disconnect the motor and see if the fault stays.

F30002 and F30003: DC link voltage

Overvoltage often means braking or supply problems; undervoltage points to supply or precharge faults.

F30004: heatsink overtemperature

Check the fan, the airflow and the enclosure temperature.

F30005 and F30021: overload and ground fault

Check load, motor cable and motor insulation.

04Verification

How a repaired Siemens drive is tested

After component-level repair, the drive is powered up on a test rig, the power stage and feedback circuits are checked, and the drive is run with a servo motor under load. Your drive comes back with its own settings and serial history, and a printed test report.

If the motor is the real cause, the drive repair alone will not hold. When the alarm points to feedback or overcurrent, send the motor too: see Siemens servo motor repair and encoder repair. We are an independent multi-brand repair company, not an OEM service centre.

05Turnaround

Siemens servo drive repair turnaround

Emergency: same day

For a stopped line. Send the label photo and alarm code first.

Urgent: 3 days

Once the fault is confirmed on inspection.

Standard: 7 days

Planned repair with the full test and a printed report.

Time depends on the fault and on parts. What affects repair cost.

06How to send

How to send the drive

You can send a drive from anywhere in India. Talk to us before you courier, so the unit is expected and logged on arrival.

  1. Send the nameplate

    WhatsApp a clear photo of the drive label, the alarm or fault code and what the machine was doing when it failed.

  2. We confirm repairability

    We tell you whether we can test and repair that model before anything is shipped.

  3. Courier or pickup

    Courier the drive, with the motor if the alarm points to feedback or overcurrent, to our Chennai or Puducherry bench.

  4. Inspection and quote

    The drive is opened and inspected. You get the findings and a quote before work starts.

  5. Repair, test, dispatch

    Repaired at component level, tested with a servo motor under load, then dispatched with a printed test report.

Siemens servo drive repair questions

More on the FAQ page.

Do you repair Siemens servo drives in India?

Yes. We repair Siemens servo drives and amplifiers at component level, test them with a servo motor under load and return them with a printed test report. Send the label photo and alarm code on WhatsApp and we confirm repairability before you courier.

Are you an Siemens service centre?

No. Star Automations is an independent multi-brand repair company, not an OEM service centre. The brand name only describes the equipment we repair.

Can you repair the motor and the drive together?

Yes. When the alarm points to feedback or overcurrent we test the drive with the motor, so a motor fault does not bring the alarm back.

What do I send for a quote?

The drive label photo, the alarm code, the motor nameplate and what the machine was doing at the time of failure.

Send the drive label and alarm code. We confirm repairability before you courier.
