CONVER Product Lines We Repair
Our engineers are trained on the full CONVER product range. Below are the major product families we service.
FC Series Frequency Converters
Three-phase AC to DC frequency conversion modules used in precise speed control applications. Common issues include capacitor bank failures, thyristor faults, cooling fan malfunctions, and control board degradation under high ambient temperatures typical in Indian factories.
SS Series Soft Starters
Electronic soft-start units for AC motor acceleration control, reducing inrush current and mechanical stress. Repair commonly involves thyristor replacement, control circuit board rework, thermal sensor calibration, and power semiconductor testing.
MC Series Motor Controllers
Integrated motor control and monitoring systems with analog and digital I/O. Typical faults include contactor coil burnout, control relay failures, signal conditioning circuit faults, and firmware corruption requiring EEPROM reprogramming.
DV Series DC Drive Units
Dedicated DC motor speed and torque control systems for mills, pumps, and conveyor applications. Repair scope includes armature current sensing circuit faults, field weakening circuit malfunctions, power module testing, and analog control loop calibration.
REC Series Regenerative Converters
Power regeneration modules for cranes, hoists, and elevators that convert braking energy back to the AC supply. Common failures involve diode bridge degradation, DC link capacitor swelling, and control synchronization circuit faults.

Common CONVER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONVER equipment arriving at our workshop.
- ✓Capacitor bank failure in FC series converters — Electrolytic capacitors in the DC link degrade rapidly under sustained high ambient temperatures (45-55°C) common in Indian factory floors and outdoor installations, causing bulging, leakage, and eventual short-circuit conditions that trigger protective shutdowns.
- ✓Thyristor and power semiconductor failures — Gate drive circuit faults, inadequate heat sink contact, or transient voltage spikes from switching operations cause thyristor junction degradation, leading to gate open-circuit or leakage current conditions that disable converter output.
- ✓Control board firmware corruption or EEPROM corruption — Power supply transients, electrostatic discharge during service, or extended operation beyond rated component lifespan corrupt the microprocessor code or parameter memory, causing erratic behavior, fault codes ERR-12 or ERR-14, or complete unit lockout.
- ✓Soft starter thyristor gate control signal loss — Control circuit board traces crack due to vibration and thermal cycling; optoisolator chips fail; or gate driver IC supply voltage droops below threshold, causing asymmetric thyristor conduction, phase imbalance, and sudden motor load drop.
- ✓Cooling fan failure or thermal sensor malfunction — Brushless DC fan motors wear out after 3-5 years of continuous operation; thermal sensor (PT100 or NTC thermistor) drifts out of calibration or develops open-circuit condition, causing overtemp shutdown even at normal junction temperatures.
- ✓Analog signal conditioning and sensor input errors — Shielded cables in noisy environments lose conductor-to-shield integrity; instrumentation amplifier chips degrade; potentiometers develop dry-joint solder connections; or current sensor linearization circuits drift, causing erratic speed feedback and closed-loop control instability.

Frequently Asked Questions — CONVER Repairs
Do you repair CONVER equipment anywhere in India?+
Yes, absolutely. Synchronics Electronics repairs the complete CONVER product portfolio — frequency converters, soft starters, motor controllers, DC drives, and regenerative converters. We offer PAN-India door pickup and logistics from major metros including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and Surat. All repairs are performed at our 180-engineer facility in Vadodara, Gujarat. We typically deliver repaired equipment within 10-15 working days.
What is the typical repair turnaround time for CONVER frequency converters?+
Standard CONVER converter repairs (capacitor replacement, thyristor testing, control board rework) take 8-12 working days. Complex cases involving firmware corruption or multi-component failures may extend to 15-18 days. We offer expedited turnaround (5-7 days) for critical production equipment at a premium. All repairs include full functional testing, temperature stress testing, and a 12-month warranty.
Do you stock spare parts for CONVER soft starters and drives?+
Yes. Synchronics maintains an active inventory of CONVER spare parts including thyristors (SKN, IXYS equivalents), electrolytic capacitors rated for industrial duty, gate driver ICs, thermal sensors, optoisolators, and complete PCB assemblies for SS and FC series units. We also source genuine CONVER original components through authorized distributors. Spare part availability accelerates repair cycles significantly — typically reducing turnaround by 3-5 days.
How does Synchronics diagnose CONVER equipment without having working units nearby?+
We use a structured diagnostic approach: customers describe fault symptoms and error codes; we request photographs of LED indicators and display messages; we perform electrical bench testing (component curve tracing, resistance mapping, capacity testing) immediately upon arrival; and we use simulation and load-testing rigs to verify function before return. For mills and plants, we also offer on-site diagnostic support via our field engineers.
What warranty and support do you provide after CONVER repair?+
All Synchronics CONVER repairs carry a 12-month full parts and labor warranty. We provide technical support via phone and email for the life of the equipment, free firmware updates when CONVER releases patches, and detailed technical reports documenting faults found and repair actions taken. For critical plant equipment, we offer optional extended 24-month warranty and on-site spares kits.
How do I send my CONVER 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 CONVER 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 CONVER 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 CONVER 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.
