CHINESE PRODUCT Product Lines We Repair
Our engineers are trained on the full CHINESE PRODUCT product range. Below are the major product families we service.
Variable Frequency Drives (VFDs)
Chinese VFDs control motor speed and torque across pumps, fans, and compressors in Indian industries. Common faults include IGBT failures, capacitor degradation, thermal runaway, and parameter corruption. Synchronics performs module replacement, capacitor bank refurbishment, and firmware recovery.
Programmable Logic Controllers (PLCs)
Chinese PLCs manage machine sequences in textile, packaging, and food processing plants. Repair focuses on input-output module failures, memory corruption, communication port damage, and power supply faults. Synchronics restores functionality through component-level diagnostics and program backup recovery.
Human-Machine Interfaces (HMIs)
Chinese touchscreen HMIs provide operator control and real-time monitoring in manufacturing and process plants. Common issues include display panel failures, communication timeouts, memory errors, and power module defects. Synchronics restores touchscreen responsiveness and communication protocols.
Servo Motion Control Systems
Chinese servo drives and motors enable precision positioning in CNC machines, textile machinery, and packaging automation. Faults include encoder signal loss, phase loss on AC inputs, thermal shutdown, and position loop instability. Synchronics recalibrates servo loops and replaces faulty power electronics.
Power Supply Modules
Chinese industrial power supplies convert mains AC to regulated DC for PLCs, HMIs, and field instruments. Common failures include blown rectifier bridges, shorted filter capacitors, and open-circuit transformers. Synchronics performs full load testing and component replacement.
Soft Starters and Motor Soft Start Controllers
Chinese soft starters reduce inrush current in pump and fan motors across water treatment, HVAC, and industrial plants. Faults include thyristor failures, control signal loss, cooling fan blockage, and parameter reset issues. Synchronics replaces thyristor modules and recalibrates ramp-time settings.

Common CHINESE PRODUCT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHINESE PRODUCT equipment arriving at our workshop.
- ✓VFD IGBT module short circuit failure — Chinese VFDs experience IGBT thermal stress under overload conditions, particularly in humid Indian factory environments where dust and moisture accelerate insulation breakdown. Power surges from mains supply fluctuations also trigger catastrophic IGBT gate-source failures.
- ✓PLC memory corruption and program loss — Chinese PLCs lose stored programs due to power supply brownouts, abrupt shutdowns without proper UPS backup, or corrupted EEPROM sectors. Frequent power cycling in Indian industrial environments degrades memory cell integrity over time.
- ✓HMI touchscreen panel unresponsiveness — Chinese HMI screens suffer touch sensitivity loss due to cracked glass, moisture ingress under humid conditions, or failed capacitive sensing circuitry. Repeated contact wear and thermal cycling degrade touch electrode adhesion.
- ✓Servo drive encoder communication timeout — Chinese servo systems lose encoder signal due to damaged cables, corroded connectors, or failed encoder interface circuits. Electrical noise from VFDs and motor contactors corrupts encoder pulse counting in unshielded Chinese installations.
- ✓Power supply overcurrent and thermal shutdown — Chinese industrial power supplies fail when connected to faulty loads drawing excessive current, or when internal filter capacitors degrade over 5-7 years of continuous operation in hot Indian plants. Inadequate heatsinking causes thermal runaway.
- ✓Soft starter thyristor gate drive failure — Chinese soft starters experience thyristor gate drive IC failures when subjected to sustained overload currents, causing abnormal voltage spikes. Phase imbalance in three-phase mains supply stresses individual thyristor gates unevenly.

Frequently Asked Questions — CHINESE PRODUCT Repairs
Do you repair Chinese product equipment anywhere in India?+
Yes. Synchronics repairs the full range of Chinese industrial electronics — drives, PLCs, HMIs, servo systems, and power supplies. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other Indian cities. All repairs are completed in our central facility in Vadodara, Gujarat, with detailed fault reports and video diagnostics provided to customers.
What is the typical turnaround time for Chinese VFD repair?+
Most Chinese VFD repairs are completed within 5-7 working days. Routine issues like capacitor replacement and IGBT module failures are faster; complex parameter corruption or firmware recovery may take 10-14 days. Synchronics provides daily status updates and expedited service for critical plant shutdowns, often completing urgent repairs within 48 hours.
Can Synchronics reprogram Chinese PLCs if the original program is lost?+
Yes. If the PLC memory is corrupted, Synchronics retrieves the program from customer backups, AutoCAD schematics, or I/O terminal descriptions. Our engineers reverse-engineer the control logic and reprogram the PLC, then validate all sensor inputs and output functions against the manufacturing process. We test under simulated load conditions before shipment.
Why do Chinese servo drives lose encoder signal in Indian factories?+
Chinese servo systems are often installed with unshielded encoder cables running near high-power VFDs and motor circuits. Electromagnetic interference (EMI) from switching converters corrupts encoder pulse signals, causing timeout errors and position loss. Synchronics replaces cables with shielded M12 connectors, adds ferrite filters, and separates encoder power supplies — eliminating noise coupling and ensuring stable servo loop operation.
Does Synchronics offer preventive maintenance for Chinese industrial electronics?+
Yes. Synchronics provides on-site preventive maintenance for Chinese VFDs, PLCs, and HMIs — including thermal imaging to detect hot components, capacitor health testing, firmware version audits, and parameter backups. We recommend scheduled maintenance every 6-12 months depending on ambient conditions and duty cycle. Preventive care reduces emergency downtime and extends equipment life by 30-40%.
How do I send my CHINESE PRODUCT 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 CHINESE PRODUCT 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 CHINESE PRODUCT 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 CHINESE PRODUCT 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.
