SWAN Equipment We Repair — By Category
SWAN Product Lines We Repair
Our engineers are trained on the full SWAN product range. Below are the major product families we service.
SWAN Frequency Converters (AC Drives)
SWAN three-phase and single-phase frequency converters control motor speed and torque in pumps, compressors, and conveyor systems. Common failures include capacitor degradation, IGBT burnout, and control board thermal damage from ambient temperatures exceeding 55°C in Indian mills and foundries.
SWAN Programmable Logic Controllers (PLCs)
Compact and modular SWAN PLCs manage sequential control, data logging, and networked automation in textile mills and packaging lines. Repairs address corrupted program memory, failed analog input modules, communication port failures, and relay output card faults common in humid Indian factory environments.
SWAN Servo Drive Systems
Precision servo drives and motion controllers for CNC machine tools, injection molding machines, and precision positioning systems. SWAN servo electronics suffer encoder communication loss, position loop instability, and power stage failures due to coolant ingress in metalworking shops.
SWAN Power Supply Units (PSUs)
Industrial-grade 24 VDC, 48 VDC, and redundant PSUs powering distributed I/O, sensors, and control networks. Failure modes include rectifier bridge failure, transformer core saturation, and capacitive bank breakdown triggered by voltage surges common in Indian power infrastructure.
SWAN Human Machine Interfaces (HMIs)
Touchscreen panels and operator displays for real-time process monitoring in sugar mills, pharma plants, and food processing. Common SWAN HMI faults include LCD backlight failure, capacitive touch sensor degradation, and Ethernet interface board corrosion.
SWAN Communication Modules and Gateways
SWAN Profibus, Ethernet, and Modbus interfaces enable networked industrial control. Failures include connector oxidation, protocol stack crashes, and firmware corruption blocking production data flow in integrated manufacturing environments.

Common SWAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SWAN equipment arriving at our workshop.
- ✓Capacitor degradation causing voltage ripple and shutdown — SWAN frequency converters and PSUs operate in uncontrolled ambient temperatures across Indian foundries and textile mills. Electrolytic capacitor aging accelerates above 45°C, causing ESR rise and DC bus voltage collapse during transient load spikes.
- ✓IGBT module failure with burnt gate drive traces — SWAN servo and converter IGBTs fail catastrophically when coolant mist, metallic dust, or humidity ingress bridges gate-emitter spacing in CNC shops. Gate drive isolation breakdown causes uncontrolled current and thermal runaway.
- ✓Encoder communication loss causing servo runaway error — SWAN servo drives lose incremental encoder feedback due to connector oxidation, shielded cable abrasion, or EMI from nearby welding equipment common in Indian auto component shops. Loss of position feedback triggers fault E42 and motor coast-down.
- ✓PLC program memory corruption or boot failure — SWAN PLC flash memory corruption occurs during power loss mid-write, electrical transient damage to program storage chips, or firmware update interruption. Corrupted code prevents boot sequence completion, leaving equipment in safe-state fault mode.
- ✓HMI touchscreen backlight failure or LCD image loss — SWAN HMI backlights fail from thermal cycling in non-air-conditioned Indian plants, transformer dropout, or inverter capacitor aging. LCD driver IC failures cause image ghosting or complete loss with audible beeping.
- ✓Ethernet interface not communicating or DHCP timeout — SWAN industrial Ethernet modules suffer PHY chip failures from transient overvoltage, transformer primary coil open-circuit from thermal stress, or protocol stack crashes after extended runtime in hot factory floors exceeding specifications.

Frequently Asked Questions — SWAN Repairs
Do you repair SWAN equipment anywhere in India?+
Yes. Synchronics repairs the complete SWAN product range—frequency converters, PLCs, servo drives, HMIs, power supplies, and communication modules. We offer same-day pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all metro cities. All repairs are performed at our advanced facility in Vadodara, Gujarat, with a 7-10 day standard turnaround and 24-hour emergency service available for critical production equipment.
What is included in Synchronics SWAN frequency converter repair?+
SWAN frequency converter repairs include full capacitor bank replacement, IGBT module testing and replacement if needed, control board component-level repair, power stage isolation testing, thermal imaging under load, and software parameter restoration. We perform no-load spin tests on connected motors to validate torque and speed response before returning units to your production line.
Can you repair SWAN PLCs with corrupted or lost programs?+
Yes. Synchronics recovers SWAN PLC program memory using specialized diagnostic firmware and can reprogram controllers from your backup files. If backups are unavailable, we work with your process engineers to rebuild logic based on documented control sequences. All reprogrammed units undergo full I/O testing with simulated inputs before shipment.
How long does SWAN servo drive repair typically take?+
Standard SWAN servo drive repair takes 5-7 business days including diagnostic testing, component replacement, encoder simulation testing, and load-cell validation. Critical production equipment qualifies for expedited 48-hour repair with additional service charges. We maintain stock of common SWAN servo ICs, power stages, and gate drivers to minimize wait time for spare parts.
What warranty do you offer on repaired SWAN equipment?+
All SWAN equipment repaired by Synchronics carries a 12-month manufacturer-equivalent warranty covering parts and labor for the same fault. Extended 24-month warranty is available at checkout. Warranty covers field failure but excludes damage from misapplication, incorrect power supply, or environmental contamination beyond design specifications. Remote diagnostic support is complimentary during warranty period.
How do I send my SWAN 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 SWAN 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 SWAN 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 SWAN 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.
