FRECON Product Lines We Repair
Our engineers are trained on the full FRECON product range. Below are the major product families we service.
FR100 and FR200 Series VFDs
General-purpose variable frequency drives rated 0.75 kW to 630 kW for pump, fan, and conveyor applications. Common failures include IGBT module burnout, capacitor bank degradation, and control board processor faults triggered by voltage spikes and thermal stress in Indian plant environments.
FR-EL Series Servo Drives
Precision servo drive controllers for spindle and multi-axis motion control in machine tools and textile equipment. Typical repair issues include encoder communication loss, position loop instability, and firmware corruption under Indian grid voltage fluctuations.
FR-CSC Coordination Controller
Multi-drive coordination system for synchronized operation in parallel-pump and dual-motor applications. Failures stem from CAN bus communication breakdown, synchronization module faults, and firmware version incompatibility during upgrades.
FR-A500 Series Industrial VFDs
Heavy-duty variable frequency drives for cement mills, crushers, and high-inertia loads (up to 400 kW). Repair challenges include thermal runaway in summer-operated plants, brake resistor failure, and EMC shielding degradation from vibration.
FR-D700 Series Matrix Converter Drives
Direct AC-to-AC converters for energy-efficient operation in crane and hoist systems. Typical issues include thyristor gating circuit failure, control signal interference, and output reactor saturation under unbalanced load conditions.
FR-E840 Compact Frequency Converters
Space-saving single and three-phase converters for small machine tools and packaging equipment. Repair focuses on cooling fan motor failure, DC bus voltage regulation drift, and input filter resonance instability.

Common FRECON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FRECON equipment arriving at our workshop.
- ✓IGBT module open circuit fault code — FRECON IGBT power modules (FR100/FR200 series) suffer junction solder fatigue under thermal cycling between 40°C summer operation and cooling ramp-downs. India's dry-bulb temperatures and mill dust insulation create accelerated thermal stress on gate-driver circuits.
- ✓Encoder loss of signal error E.ENCL — FRECON FR-EL servo drives rely on incremental encoder feedback for position control. High-frequency noise from adjacent motor cables and unshielded encoder connectors in Indian textile mills causes signal dropout, triggering E.ENCL fault and drive shutdown.
- ✓Capacitor bank voltage regulation failure — FRECON FR-A500 and FR200 drives use large electrolytic capacitor banks that swell and fail under sustained 380-415V mains ripple and harmonic distortion typical in Indian industrial grids. Chloride and humidity promote capacitor leakage and ESR rise.
- ✓CAN bus communication timeout - FR-CSC coordination loss — FRECON FR-CSC multi-drive coordinators use CANopen protocol across twisted-pair shielded cable. Improper grounding, moisture ingress at cable terminations, and loose M12 X-coded connectors in wet chemical plants break communication between primary and secondary drives.
- ✓Firmware corruption or stuck bootloader state — Power supply interruptions during FRECON firmware upload or voltage transients from unprotected industrial sites corrupt flash memory in FR100/FR200 control boards. Indian power quality fluctuations (±10% voltage sag) and sudden grid losses trigger bootloader lock-up.
- ✓Over-temperature shutdown with thermal sensor malfunction — FRECON drives employ NTC thermistors on heat sinks for over-temperature protection. Indian cement mills and foundries subject heatsinks to metal dust accumulation, reducing convective cooling. Thermistor aging and sensor cable insulation breakdown cause false over-temperature trips.

Frequently Asked Questions — FRECON Repairs
Do you repair FRECON equipment anywhere in India?+
Yes. Synchronics repairs the full FRECON product range — VFDs, servo drives, coordinators, and motion controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other cities. All repairs are done in our central facility in Vadodara, Gujarat, with 24-48 hour turnaround for most FRECON drive failures.
Can you repair FRECON FR100/FR200 drives with power module failures?+
Yes, absolutely. FRECON IGBT power module burnout is one of the most common failures we repair. Synchronics stocks genuine and equivalent IGBT modules for FR100 and FR200 series drives and performs full power stage testing post-repair including gate drive verification and thermal stress cycling to ensure long-term reliability in Indian plant conditions.
What is the typical repair cost for a FRECON FR-A500 VFD failure?+
Repair cost depends on the failure type. Capacitor bank replacement (most common) costs INR 8,000-15,000 for 110-220 kW models. IGBT module replacement ranges INR 12,000-22,000. Control board repairs are INR 6,000-10,000. Synchronics provides free diagnostic within 48 hours and detailed cost estimate before work begins. We also offer warranty on spare parts and labor.
Do you have spare parts in stock for FRECON servo drives (FR-EL series)?+
We maintain stock of critical components for FR-EL servo controllers including encoder filter capacitors, resolver interface ICs, PWM gate driver modules, and firmware programming components. For less common parts, we procure within 5-7 working days from authorized distributors. Synchronics also offers refurbished FR-EL drives as replacements during extended repairs.
Can FRECON drives be repaired if damaged by lightning strike or power surge?+
Yes, many surge-damaged FRECON drives can be repaired. Synchronics assesses secondary damage from power transient overstress — failed diode bridges, exploded capacitors, burned control traces. We replace damaged sections with surge-hardened components and install 24V DC surge suppressors to prevent recurrence. Some heavily damaged units may be uneconomical to repair; we advise customer upfront.
How do I send my FRECON 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 FRECON 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 FRECON 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 FRECON 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.
