Comprehensive inverter repair — power and control sections
IGBT modules and power section
Replacement of IGBT transistors, power diodes, galvanic opto-isolators and driver circuits. Repair of the inverter bridge — single and three-phase.
DC-link capacitors
Regeneration of the capacitor bank (electrolytic and film). Capacity and ESR measurement, preventive replacement of the entire capacitor set.
Control boards
Repair of CPU, FPGA and DSP boards. Firmware read, write and restore. Parameter backup before every repair.
Communication interfaces
Repair of Profinet, Profibus, EtherCAT, Modbus and CANopen ports. Restoring communication between inverter and PLC/SCADA.
Fans and thermal section
Cooling fan replacement, heatsink cleaning, thermal pad and paste replacement. Temperature sensor diagnostics.
EMC filters and braking resistors
Repair and replacement of EMC/RFI input filters, braking choppers and braking resistor modules.
Inverter repair: precision and speed — every hour of downtime costs money
- Parameter backup — before repair, we read and archive inverter parameters (V/f curves, ramp times, PID, communication) so that after repair the machine returns to identical operation.
- Load testing — every inverter after repair is tested on a bench simulating real motor load (inductive/resistive load bank).
- All topologies supported — single-phase, three-phase, multi-axis (common DC bus), regenerative and pump drives.
- Discontinued models — Siemens MICROMASTER, Danfoss VLT 2800/5000, ABB ACS400/600, Lenze 8200/9300 — no problem.
- 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.

Diagnostics costs 300 PLN net. If you decide to proceed with the repair, the diagnostics cost is included in the repair price — you only pay for the repair. If you decline the repair, we charge the diagnostics fee (300 PLN net). Return shipping of the inverter is free.
Yes — MICROMASTER is one of the most frequently repaired platforms in our service. We have replacement IGBT modules, capacitors and control electronics for the 420, 430 and 440 series.
Yes — before repair we read and archive all inverter parameters (if technically possible). After repair we restore them so the machine operates identically to before the failure.
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 under simulated operating conditions. 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.
