FINCOR Product Lines We Repair
Our engineers are trained on the full FINCOR product range. Below are the major product families we service.
FINCOR DC Drives (Thyristor-based)
Single and multi-phase DC motor controllers for textile spindles, winders, and hoist duty. Common faults include thyristor firing circuit failures, gate driver damage, and field weakening control instability under low-power factor supply.
FINCOR AC Vector Drives
Speed and torque control for three-phase AC motors in conveyors, pumps, and compressors. Failures often stem from IGBT module thermal stress, EMC filter capacitor degradation, and encoder signal loss in high-vibration mill environments.
FINCOR Servo Amplifiers
Precision position and velocity loop controllers for printing press registers, winding tension control, and spindle synchronization. Typical issues include Hall sensor noise immunity, resolver tracking errors, and current-loop instability on noisy DC links.
FINCOR Regenerative Controllers
Energy recovery systems for winder and unwinder duty in paper and film lines. Prone to control circuit oscillation, DC bus voltage spikes, and inverter commutation failures under dynamic load reversal.
FINCOR PLC and Motion Controllers
Industrial logic controllers and integrated motion modules with Ethernet/CANopen for synchronized multi-drive mills. Common faults include firmware corruption, I/O module failure, and Ethernet PHY layer instability in EMI-rich plant floors.

Common FINCOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FINCOR equipment arriving at our workshop.
- ✓DC drive firing circuit failure — no gate drive — FINCOR DC drives use pulse transformer and opto-isolator gate circuits. Transformer saturation from DC bias drift, or opto-coupler LED aging, blocks gate pulses to thyristors. Power supply ripple and EMI from adjacent VFDs degrade signal integrity.
- ✓Thyristor short-circuit — control voltage collapse — FINCOR thyristor stacks in DC drives short due to junction overstress during power surges, poor heatsink contact, or thermal cycling in 40-50°C Indian mill environments. Loss of gate drive and overcurrent then triggers catastrophic failure.
- ✓IGBT module thermal runaway — vector drive shutdown — FINCOR AC vector drives use discrete IGBT modules soldered to DBC copper substrates. Thermal cycling, insufficient airflow through finned heatsinks (common in dusty Indian mills), and aged thermal grease cause junction temperature to climb. Over-temperature shuts drive down.
- ✓Encoder signal loss — position loop open — FINCOR servo and drive controllers accept incremental or absolute encoder feedback. Connectors corrode in humid mill environments, shielded cables get damaged near hot spots, and stub transmission lines cause reflections. Feedback vanishes, causing servo runaway.
- ✓DC bus voltage collapse under load — regenerative drive stall — FINCOR regenerative drives experience nuisance bus voltage dips when winder motors brake hard or spindle suddenly decelerates. Undersized bulk capacitors, aged electrolytics, and poor PCB return planes degrade transient response. Control loop loses regulation.
- ✓Firmware corruption — controller boot failure or erratic logic output — FINCOR PLC and motion controller flash memory gets corrupted by power-loss during write cycles, ESD damage to firmware update port, or firmware incompatibility after non-official updates in field. Boot ROM checksums fail; drive hangs.

Frequently Asked Questions — FINCOR Repairs
Do you repair FINCOR equipment anywhere in India?+
Yes. Synchronics repairs the full FINCOR product range — DC drives, AC vector drives, servo amplifiers, regenerative controllers, and motion PLCs. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other cities. Same facility in Vadodara, Gujarat. Express logistics for critical breakdowns; turnaround is 5-7 working days for standard repair.
What is FINCOR's most common drive failure in Indian mills?+
Thyristor gate driver failure in FINCOR DC drives is the single largest issue we see. Pulse transformer saturation from EMI and aging opto-couplers block gate signals, causing loss of motor speed control. Synchronics has repaired over 800+ FINCOR DC drives since 2008 — we stock replacement transformer assemblies and re-qualify gate circuits to withstand plant EMI conditions.
Can you repair FINCOR drives with burned-out power components?+
Yes, absolutely. Synchronics specializes in surgical replacement of thyristor modules, IGBT stacks, and bridge rectifiers in FINCOR drives. We pressure-test solder joints, inspect PCB traces for secondary damage, and characterize thermal performance on load-bank before shipment. We also upgrade heatsink thermal interfaces and capacitor banks to prevent recurrence.
Do you offer on-site commissioning and spare drive stocking for textile mills?+
Yes. For large textile spindle drives and winder systems, Synchronics offers on-site installation, load-bank testing, and parameter tuning. We can stock spare FINCOR DC and AC drive units at your facility on a rental basis to minimize production downtime. Contact our textile segment team in Vadodara.
What warranty do you provide on FINCOR drive repairs?+
Synchronics provides 12-month comprehensive warranty on all repaired FINCOR drives, covering parts and labor. If the same fault reoccurs within 12 months, we repair it free. We also log every repair in our database, provide detailed test certificates, and advise on preventive maintenance intervals specific to your operating environment.
How do I send my FINCOR 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 FINCOR 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 FINCOR 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 FINCOR 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.
