DONGWON MACHINE CO. Product Lines We Repair
Our engineers are trained on the full DONGWON MACHINE CO. product range. Below are the major product families we service.
DW-ServoMax Servo Drive Systems
AC and DC servo drives for multi-axis motion control in textile looms, packaging machines, and print finishing equipment. Common repairs include encoder signal loss, thermal shutdown on high-speed spindle duty, and firmware corruption after power surges.
DW-HydraControl PLC & Hydraulic Controllers
Hardened proportional and directional control logic for press machines, die-cutting equipment, and industrial compressors. Issues include solenoid valve jams, pressure transducer drift, and analogue card failures on moisture-prone factory floors.
DW-TextileOS Programmable Logic Controllers
Compact PLCs designed for textile mill automation, loom synchronization, and production scheduling. Repairs address memory module failures, communication port corruption (Ethernet/RS485), and ladder logic firmware rebuild after unexpected shutdowns.
DW-PowerPack Industrial Power Supplies
Regulated 24V DC and 48V DC supplies for factory automation networks. Common faults include capacitor aging, rectifier diode failure, and overvoltage protection circuit malfunction in dusty textile and paper mill environments.
DW-MotionLink Inverter & VFD Systems
Vector-controlled variable frequency drives for pump motors, compressor duty, and conveyor systems in packaging lines. Typical failures: IGBT module thermal stress, DC bus capacitor aging, and firmware conflicts after firmware updates.
DW-HMI Touch Panel Operator Interfaces
7-inch and 10-inch industrial touchscreen panels for loom control rooms and packaging plant dashboards. Repairs include display backlight failure, resistive touch sensor calibration, and communication driver reinstallation.

Common DONGWON MACHINE CO. Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DONGWON MACHINE CO. equipment arriving at our workshop.
- ✓Encoder signal loss on DW-ServoMax drives — Dongwon servo drives use quadrature encoders; cable shielding degradation or connector corrosion in humid textile mills causes intermittent encoder dropout, triggering position error faults. Moisture intrusion is common on mill floors.
- ✓DW-HydraControl proportional solenoid valve failure — Hard water deposits and industrial coolant contamination in Dongwon hydraulic systems cause solenoid coil resistance to spike, preventing full valve closure. This is prevalent in Indian paper and textile mills with untreated water supplies.
- ✓DW-TextileOS PLC memory card corruption — Dongwon compact PLCs store ladder logic on EEPROM cards; static discharge during module swap-out or improper shutdown during power loss corrupts program memory. Multi-spindle looms are especially vulnerable during monsoon electrical transients.
- ✓DW-PowerPack 24V supply voltage sag and shutdown — Electrolytic capacitors in Dongwon power supplies age rapidly in hot, humid Indian factories; internal resistance rises, reducing output filtering. Under high load (servo drives + PLC + solenoids), voltage dips below 22V, triggering brownout resets.
- ✓DW-MotionLink IGBT module thermal failure — Dongwon VFD motor drives use low-cost IGBT modules; inadequate heatsink cooling in poorly ventilated control cabinets causes junction temperature overshoot. Drives de-rate and shut down during peak summer or high-duty compressor cycles.
- ✓DW-HMI touchscreen panel display backlight dimming or failure — Dongwon 10-inch HMI panels use CCFL backlights; inverter circuit capacitors dry out or backlight tube filament fails after 8-10 years of continuous operation in 24x7 Indian production facilities.

Frequently Asked Questions — DONGWON MACHINE CO. Repairs
Do you repair Dongwon Machine Co. equipment anywhere in India?+
Yes. Synchronics repairs the complete Dongwon Machine Co. product range — servo drives, hydraulic controllers, PLCs, power supplies, VFDs, and HMI panels. We offer PAN-India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and all tier-2 industrial cities. All repairs are carried out at our ISO-certified facility in Vadodara, Gujarat, with same-week turnaround on most jobs.
How do I identify a faulty Dongwon servo drive or controller?+
Dongwon drives and controllers display LED error codes or fault messages on connected HMI screens. Common indicators are red status LEDs, intermittent motor stalling, loss of position feedback, or unresponsive solenoid valves. Synchronics technicians can perform on-site diagnostic tests using multimeters and oscilloscopes to pinpoint faults. We then quote repair cost (component replacement, firmware reload, or full module exchange) before proceeding.
Can Synchronics repair Dongwon HMI touchscreen panels and reprogram them?+
Yes. Synchronics repairs Dongwon HMI displays including DW-TP7S and DW-TP10 series — backlight replacement, touchscreen calibration, and firmware reinstallation. We also reprogram user screens and communication drivers to reconnect with your PLC network. Turnaround is typically 3-5 days depending on custom programming complexity.
What warranty do you offer on Dongwon Machine Co. repairs?+
Synchronics provides a 12-month return-to-service warranty on all component replacements and repaired electronic modules (servo drives, PLCs, power supplies, inverters). If a repaired unit fails within 12 months due to the original fault, we repair or replace it at no cost. Extended warranty and on-site support plans are available for mission-critical equipment in textile mills and production lines.
Does Synchronics stock Dongwon spare parts and replacement modules?+
Synchronics maintains strategic inventory of common Dongwon replacement modules — servo drive boards, PLC memory cards, power supply units, and inverter IGBTs. For rare or obsolete Dongwon parts, we source directly from authorized distributors or recommend modern equivalent substitutes (e.g., ABB or Danfoss VFDs in place of old Dongwon drives). Lead time for genuine Dongwon spares is typically 2-3 weeks from Korea.
How do I send my DONGWON MACHINE CO. 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 DONGWON MACHINE CO. 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 DONGWON MACHINE CO. 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 DONGWON MACHINE CO. 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.
