FOSS ELECTRIC Equipment We Repair — By Category
FOSS ELECTRIC Product Lines We Repair
Our engineers are trained on the full FOSS ELECTRIC product range. Below are the major product families we service.
FOSS COMFORT Series Variable Frequency Drives
Single and three-phase VFDs for motor speed control in industrial applications. Common faults include capacitor degradation, cooling fan failure, and IGBT module breakdown under thermal stress.
FOSS SERVO DRIVE Series
Precision servo amplifiers and motion control drives for synchronous motor applications in packaging and printing machinery. Prone to encoder signal faults and PID tuning errors affecting loop stability.
FOSS SMART Control Modules
Intelligent control units with embedded logic for machine coordination and speed ramping. Display failures, parameter memory corruption, and communication interface breakdowns are typical repair cases.
FOSS Spindle Drive Series
Specialised high-frequency drives for spindle motor control in CNC, grinding, and textile machinery. Thermal runaway and frequency regulation faults are common under sustained high-speed operation.
FOSS Soft Starter Series
Electronic soft-starting modules reducing inrush current in three-phase motor applications. Thyristor misfiring and phase synchronisation issues lead to uneven motor acceleration and mechanical shock.
FOSS Power Supply Modules
Regulated DC power supplies for servo and stepper motor drive circuits. Transformer core saturation, rectifier bridge failures, and output voltage regulation drift are typical faults.
Why Choose Synchronics for FOSS ELECTRIC Repairs?

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 FOSS ELECTRIC 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 FOSS ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FOSS ELECTRIC equipment arriving at our workshop.
- ✓FOSS VFD E01 or E02 Overvoltage Fault Code — DC bus voltage exceeds safe operating limits, typically caused by regenerative braking energy during rapid load deceleration or input supply instability. In Indian industrial environments with weak grid infrastructure, voltage spikes are frequent.
- ✓FOSS Servo Drive Position Following Error Loss — Encoder cable shielding degradation, bearing wear reducing shaft rigidity, or drift in servo loop gain tuning. High-vibration textile machinery environments accelerate encoder connector corrosion in FOSS servo drives.
- ✓FOSS COMFORT Drive Display Panel Blank or Erratic Display — LCD panel ribbon cable loosening due to thermal cycling, microcontroller memory chip corruption from power transients, or faulty backlight LED driver circuit.
- ✓FOSS Spindle Drive Frequency Oscillation or Instability — Feedback filter capacitor degradation causing control loop instability, or phase-locked loop (PLL) failure in high-frequency drive circuits. Textile spindle and CNC grinding applications stress FOSS spindle drives continuously.
- ✓FOSS Soft Starter Thyristor Misfire or Phase Imbalance — Gate drive circuit failure preventing simultaneous thyristor triggering, or phase-synchronisation detection circuit fault. Unbalanced three-phase supply in Indian industrial areas accelerates gate drive component aging in FOSS soft starters.
- ✓FOSS Power Supply Output Voltage Drift or Ripple Increase — Electrolytic capacitor dry-out reducing effective capacitance, transformer core saturation from DC bias, or feedback regulation amplifier bias drift due to temperature stress.

Frequently Asked Questions — FOSS ELECTRIC Repairs
Do you repair FOSS ELECTRIC equipment anywhere in India?+
Yes. Synchronics repairs the full FOSS ELECTRIC product range — VFDs, servo drives, spindle drives, soft starters, control modules, and power supplies. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all major cities. All repairs are completed at our main facility in Vadodara, Gujarat with 48-hour turnaround for most units.
How do you handle FOSS ELECTRIC servo drive encoder faults and re-tuning?+
FOSS servo drives demand precision encoder diagnostics and tight PID loop tuning for applications like textile unwinding and synchronised conveyor control. Synchronics uses pattern generators to validate encoder feedback, performs complete loop step-response testing, and re-tunes servo gains using FOSS ELECTRIC commissioning software. We issue a full performance report and certificate before dispatch.
What is your experience with FOSS COMFORT VFD repairs in Indian textile mills?+
FOSS COMFORT drives are widely used in Indian spinning mills for spindle and winder motor control. Synchronics has repaired hundreds of COMFORT series units, specialising in capacitor bank replacement, thermal runway recovery, and regenerative braking circuit restoration. We understand the grid instability challenges in rural Indian textile hubs and design repairs accordingly.
Can Synchronics repair FOSS spindle drives for CNC and grinding machinery?+
Yes. FOSS spindle drives require specialist knowledge of high-frequency control, PLL stability, and thermal management under continuous spindle speeds. Synchronics diagnoses and repairs spindle drive frequency instability, bearing cooling system faults, and encoder synchronisation failures. We test all spindle drives on dummy load before return to ensure production-ready performance.
Do you stock FOSS ELECTRIC spare components and capacitors?+
Synchronics maintains a stock of common FOSS ELECTRIC replacement components including electrolytic capacitor modules, IGBT gate drive boards, servo feedback modules, and display panels. For rare components, we source from authorised distributors and coordinate emergency shipments. Contact our engineering team for specific part availability.
How do I send my FOSS ELECTRIC 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 FOSS ELECTRIC 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 FOSS ELECTRIC 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 FOSS ELECTRIC 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.
