AVC SPECIALISTS Product Lines We Repair
Our engineers are trained on the full AVC SPECIALISTS product range. Below are the major product families we service.
AVC PowerDrive VFD Series
Three-phase variable frequency drives ranging from 0.5 kW to 630 kW. Common faults include IGBT module failures, capacitor aging, and firmware corruption leading to loss-of-field errors and overvoltage shutdown codes.
AVC Soft Starter SS Series
Electronic soft starters for induction motors (7.5 kW to 400 kW) reducing inrush current and mechanical stress. Typical failures include thyristor triggering circuit faults, phase-loss detection module defects, and heatsink thermal issues.
AVC Regenerative Drive RG Series
Energy-recovering drives for crane hoists and conveyors with four-quadrant operation. Prone to diode bridge failures, DC bus imbalance, and regeneration resistor burnout under heavy braking loads.
AVC Control Module CM Series
Programmable logic controller modules and motion control cards for synchronized multi-motor applications. Common issues include relay module burnout, analog input card drift, and communication protocol loss on industrial Ethernet interfaces.
AVC HMI Touch Panel Series
Operator interface panels with 4-inch to 21-inch touchscreens for motor control visualization and parameter tuning. Failures include backlight LED degradation, resistive/capacitive touchscreen calibration loss, and data memory corruption.

Common AVC SPECIALISTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AVC SPECIALISTS equipment arriving at our workshop.
- ✓IGBT Module Gate Drive Failure — Thermally induced solder joint cracking within AVC PowerDrive IGBT modules after 5-7 years of continuous operation, especially in high-ambient-temperature settings (textile mills, foundries). Gate driver optocoupler degradation follows, blocking PWM signal transmission.
- ✓Capacitor Bank Dry-Out and Overvoltage Fault — Electrolytic capacitors in AVC drives degrade after 8-10 years due to glycol evaporation in high-temperature environments common in Indian steel mills and injection molding plants. DC bus voltage rises above rated limit, triggering OVF (Overvoltage Fault) code E-OV.
- ✓Thyristor Trigger Circuit Malfunction in Soft Starters — AVC SS Series soft starters rely on phase-control thyristors. Dust ingress in terminal blocks and moisture in gate-trigger transformers cause intermittent or complete loss of firing pulses to thyristor gates, resulting in erratic motor starting and phase imbalance.
- ✓Firmware Corruption and Loss-of-Sync Errors — Power surges, lightning strikes, or improper power-down sequences corrupt AVC drive firmware. Microcontroller boot fails or parameters reset to factory defaults, causing the drive to show E-SYNC or E-ROM errors and refuse communication via RS-485 or Ethernet.
- ✓Diode Bridge Rectifier Short-Circuit in Regenerative Drives — AVC RG Series regenerative drives operate in four-quadrant mode. Fatigue cycling of diode junctions under repeated braking events (crane operation, conveyor reversals) causes internal shorts, drawing excessive inrush current and blowing main input fuse repeatedly.
- ✓HMI Touchscreen Calibration Loss and Backlight Failure — AVC HMI panels in cement plants and chemical mixing facilities experience temperature cycling (-5 to +60°C) and humidity fluctuations. Resistive touch sensors lose accuracy; LED backlight phosphor darkens or burns out after 30,000-40,000 operating hours.

Frequently Asked Questions — AVC SPECIALISTS Repairs
Do you repair AVC Specialists equipment anywhere in India?+
Yes. Synchronics repairs the full AVC Specialists product range — variable frequency drives, soft starters, regenerative units, control modules, and HMI panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other metro and tier-2 cities. Repairs are completed in our 15,000 sq ft facility in Vadodara, Gujarat, with same-day diagnostic reports.
My AVC PowerDrive shows E-OV (Overvoltage) fault and won't restart. What do I do?+
E-OV in AVC PowerDrive VFDs is typically caused by aged capacitors in the DC bus or a faulty DC voltage feedback circuit. Do not restart the drive immediately — this risks IGBT damage. Contact Synchronics for emergency pickup and diagnosis. We will test capacitor ESR, replace failed units, and reprogram fault thresholds if needed. Most E-OV faults are resolved within 48 hours.
Can Synchronics repair my AVC soft starter if the thyristor modules are burned out?+
Yes. AVC SS Series soft starters use plug-in thyristor modules that are independently replaceable. Synchronics stocks OEM-equivalent thyristor cartridges and power modules. We remove the burned unit, inspect the heatsink and trigger circuit for secondary damage, install a fresh module, and run full load acceptance tests. Typical turnaround is 36-48 hours.
Is AVC drive firmware update available for plants running older PLC systems?+
Yes. Synchronics maintains a library of AVC firmware versions dating back to 2000. We can upload legacy firmware if your control system depends on specific protocol versions (Modbus RTU, Profibus, Ethernet). We also offer backward-compatibility testing to ensure your old PLC communicates correctly after firmware update. A technical consultation is recommended before proceeding.
How often should AVC Specialists equipment be serviced preventively?+
AVC drives and soft starters should be inspected annually in harsh environments (textile mills, foundries, coastal areas) and bi-annually in moderate conditions. Synchronics offers preventive maintenance packages including capacitor ESR testing, fan motor inspection, heatsink cleaning, and firmware health checks. Predictive maintenance reduces unplanned shutdowns by 60-70% and extends equipment life by 3-5 years.
How do I send my AVC SPECIALISTS unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AVC SPECIALISTS drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AVC SPECIALISTS repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AVC SPECIALISTS unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
