FW Product Lines We Repair
Our engineers are trained on the full FW product range. Below are the major product families we service.
FW Motor Drive Modules
Compact stepper and brushless DC motor drive controllers for precision industrial automation. Common issues include phase winding shorts, PWM regulation failures, thermal runaway under load, and encoder interface faults causing stalled motor conditions.
FW Industrial Control Boards
Embedded logic boards for textile machinery, packaging lines, and press control. Typical faults: relay coil burnout, capacitor aging causing voltage regulation failure, microcontroller flash corruption, and input/output isolation failures.
FW Precision Connector Systems
Heavy-duty industrial connectors and terminal blocks for high-vibration environments. Failure modes include pin corrosion, contact resistance creep, insulation degradation in humid factory floors, and crimp terminal loosening.
FW Relay and Contactors
Industrial electromechanical and solid-state relays for motor control and switchgear applications. Common defects: worn contacts causing arc pitting, coil winding insulation breakdown, and mechanical latch failure under voltage spikes.
FW Frequency Converter Modules
Compact AC frequency drive modules for spindle motors and pump applications in Indian manufacturing. Issues include IGBT gate drive failure, DC bus capacitor drying, EMC filter saturation, and thermal sensor malfunction.
Why Choose Synchronics for FW Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on FW equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common FW Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FW equipment arriving at our workshop.
- ✓FW Motor Drive Phase Winding Short Circuit — Thermal cycling and vibration in Indian textile looms and packaging machines cause insulation degradation in FW stepper motor drive windings, leading to phase-to-phase or phase-to-ground shorts. High ambient temperatures (35-45°C in factories) accelerate breakdown.
- ✓FW Control Board Capacitor Electrolyte Leakage — Aging aluminium electrolytic capacitors in FW industrial control boards dry out after 8-12 years of continuous operation in hot, humid Indian factories, especially food processing and pharmaceutical plants where moisture and chemical vapours are present.
- ✓FW Connector Pin Corrosion and Contact Resistance Creep — Moisture ingress and saline air (coastal Tamil Nadu and Maharashtra) cause oxidation on FW DIN96 and M23 connector pins. Poor contact pressure combined with vibration in press lines creates intermittent signal loss and control failures.
- ✓FW Relay Coil Open Circuit from Burnout — Voltage transients, inductive kick from unprotected solenoids, and lack of suppression diodes in Indian press control circuits cause FW relay coil insulation breakdown and open-circuit failure, especially in textile and steel mills.
- ✓FW Stepper Motor Drive Microcontroller Flash Corruption — Power supply interruptions, EMI from nearby welding equipment and high-power motor starters, and firmware bugs in older FW control boards cause microcontroller flash memory to become corrupted, resulting in erratic motor behaviour or lockup.
- ✓FW Frequency Converter IGBT Gate Drive Failure — High dV/dt switching transients, inadequate gate resistor value selection, and poor PCB layout in FW spindle drive modules (especially 5kW+ units) cause gate drive IC failures, leading to IGBT short-circuit and catastrophic DC bus failure.

Frequently Asked Questions — FW Repairs
Do you repair FW equipment anywhere in India?+
Yes. Synchronics repairs the full FW product range — motor drives, control boards, relays, connectors, and frequency converters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. Single facility in Vadodara, Gujarat ensures quality control and 7-10 day turnaround.
What is the typical repair cost and turnaround time for FW stepper motor drives?+
FW stepper drive repairs (phase rewinding, control IC replacement) typically cost 8,000-18,000 INR depending on damage severity. Standard turnaround is 5-7 working days. We provide upfront quotes after diagnostic testing. Expedited 2-3 day service available for critical production lines. All repairs include 12 months warranty.
Can Synchronics repair FW control boards with obsolete microcontroller chips?+
Yes. For older FW logic boards with discontinued microcontrollers, Synchronics can perform component-level repair, reprogram flash memory from archived firmware files, or recommend modern equivalent replacement modules. We maintain relationships with FW authorized distributors and source-compatible parts from verified suppliers across India and Germany.
Do you provide preventive maintenance and condition monitoring for FW equipment in textile mills?+
Yes. Synchronics offers annual preventive maintenance contracts for FW motor drives and control systems in textile operations. We perform thermography scans, measure capacitor ESR, test relay contact pressure, and clean connectors. Condition-based monitoring reduces unplanned downtime — common in high-speed looms and spinning frames across Gujarat and Maharashtra mills.
What testing standards do you follow for FW frequency converters after repair?+
All FW frequency converters (VFDs and spindle drives) undergo full load testing at calibrated test benches, EMC immunity testing, thermal stability verification at 50°C ambient, and high-potential (hipot) insulation testing at 2x rated voltage. We follow IEC 60950 and ISO 13849 safety standards. Test certificates provided with every unit.
How do I send my FW 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 FW 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 FW 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 FW 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.
