DSP/FPGA control boards
Repair of control boards (DSP, FPGA, microcontrollers). Parameter read and write — backup copy before repair.
Communication interfaces
Repair of EtherCAT, Profinet, SERCOS, DRIVE-CLiQ ports. Restoring axis communication with CNC or PLC system.
Servo motor encoders
Replacement or regeneration of absolute and incremental encoders. Encoder cable repair.
Servo motor mechanics
Bearing replacement, shaft seal service, electromagnetic brake repair, winding and PMSM magnet diagnostics.
Servo drive repair: precision and speed — every stopped axis costs money
- Drive parameter backup — before repair, we read and archive servo drive parameters (speed, current, control loops) so that after repair the machine returns to identical operation.
- Load testing — every servo drive after repair is tested on a bench simulating real motor load.
- All topologies supported — single-axis, multi-axis (SINAMICS S120, IndraDrive Mi), drives with central power supply (DC-bus).
- Servo motor repair — comprehensive: encoders, bearings, seals, brakes, winding diagnostics.
- Fast turnaround — diagnostics: 1–3 days, repair after approval: 5–7 business days (after receipt of necessary components). Express mode available. As a rule — time may be extended depending on component availability and repair complexity; deadlines agreed individually.
- 12-month warranty — on all work performed, no exclusions or catches.

Yes — SIMODRIVE 611D/611U/611A is one of the most frequently repaired platforms in our service. We have components for IGBT, capacitor and control electronics replacement for this series.
Yes — before repair we read and archive all drive parameters (if technically possible). After repair we restore them so the machine operates identically to before the failure.
Yes — we perform diagnostics and repair of servo motors: absolute and incremental encoders, bearings, shaft seals, electromagnetic brakes, winding diagnostics (resistance, insulation) and PMSM magnets.
Diagnostics and quote: up to 5 business days. Repair after quote approval: typically 5–7 business days (after receipt of necessary components). For stopped machines we use priority mode. After repair we perform load testing. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
In that case we return the device; we charge the diagnostics fee (300 PLN net). If you approve the repair, the diagnostics cost is included in the price. We can help find a replacement or advise on drive system modernization.
