Common Questions

Frequently Asked
Questions

Have questions about sourcing, programming, or upgrading Vfd Repair systems in Chennai? Find expert answers below.

Ask Us Directly
Most of the variable frequency drives we receive present errors related to overcurrent, overvoltage on the DC bus, heat dissipation failures, or communication dropouts. These are typically caused by worn-out dynamic braking systems, degraded electrolytic capacitors, clogged heatsinks, failed cooling fans, or blown input-rectifier bridges. Our VFD Repair Services resolve all of these issues down to the component level.
Yes, we dispatch skilled field automation engineers to all primary industrial zones in Chennai, including Sriperumbudur, Oragadam, Ambattur, Guindy, and Thirumudivakkam. Our team can perform on-site diagnostic checks, read error histories, test insulation resistance, adjust parameters, and decide if the VFD can be safely repaired on-site or needs to go to our lab.
Our engineering staff has extensive experience servicing variable frequency drives across all prominent automation brands. This includes ABB (ACS range), Siemens (SINAMICS, Micromaster), Danfoss (VLT range), Yaskawa (A1000/GA700), Schneider Electric (Altivar series), Allen-Bradley (PowerFlex series), Delta, and Fuji Electric. We maintain original technical diagrams and software programs for these systems.
Testing is the most critical stage of our VFD Repair Services. Every drive repaired at our SIDCO Thirumudivakkam facility undergoes strict static and dynamic testing. The drive is powered up and its outputs are checked under no-load conditions first. Next, it is coupled to a dynamic motor rig and loaded progressively to check output current balance, thermal stability, and speed loop control accuracy.
Repairing a VFD is highly economical, with costs usually ranging from 20% to 45% of the price of a replacement drive. This is especially true for large horsepower drives (above 30 kW) or legacy drives where new replacements would require physical modification of control panels, custom cable routing, and lengthy PLC code modifications.
We provide a comprehensive 6-month warranty on all component-level repairs and spare parts integrated by our technicians. We use only premium-grade, original OEM replacement semiconductors, capacitors, and cooling systems, which ensures long-term operational reliability of your variable frequency drives.
