HEXIN Product Lines We Repair
Our engineers are trained on the full HEXIN product range. Below are the major product families we service.
HEXIN Variable Frequency Drives (VFD)
HEXIN VFD series includes compact 0.75 kW to 250 kW three-phase frequency converters widely used in pump motors, compressors, and conveyor systems across Indian food, textile, and chemical plants. Common repair issues include IGBT module failure, capacitor bank degradation, and control board MCU faults causing speed regulation loss or motor protection trips.
HEXIN Servo Drive & Motor Systems
HEXIN servo positioning systems provide closed-loop motion control for precision machinery, textile loom automation, and CNC applications. Faults typically involve encoder connection loss, servo loop instability, or parameter corruption leading to positioning errors or emergency stop triggers on Indian manufacturing lines.
HEXIN Programmable Logic Controllers (PLC)
HEXIN compact and mid-range PLCs control factory automation sequences in Indian pharmaceutical, packaging, and assembly industries. Common faults include input/output module failures, communication port degradation, program memory corruption, and real-time clock battery depletion affecting process timing.
HEXIN Industrial HMI Touchpanels
HEXIN human-machine interface panels ranging from 4-inch to 15-inch displays interface with production machinery across Indian textile mills, dairy plants, and chemical processors. Repair issues include LCD backlight failure, touch sensor degradation, RS232/Ethernet port shorts, and firmware crashes preventing operator access to machine controls.
HEXIN Soft Starters & Motor Protection Units
HEXIN electronic soft starters reduce motor inrush current in Indian pump houses, HVAC systems, and centrifuge applications. Common faults include thyristor gate drive failures, ramp control circuit malfunctions, and protection relay calibration drift causing nuisance trips or inadequate motor protection.
HEXIN Communication Modules & Industrial Gateways
HEXIN fieldbus and Ethernet modules enable real-time data exchange between drives, PLCs, and SCADA systems in integrated Indian manufacturing plants. Repair work includes RS485 transceiver restoration, connector pin corrosion removal, firmware re-flashing for Modbus/TCP protocol recovery, and galvanic isolation circuit repair.

Common HEXIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HEXIN equipment arriving at our workshop.
- ✓IGBT module thermal runaway and short circuit — HEXIN VFD power modules fail when cooling fan bearings seize or heatsink fins clog with lint/dust common in Indian textile mill environments. Thermal stress causes solder joint degradation at IGBT gate traces, leading to leakage currents and cascading gate drive failures.
- ✓Capacitor bank ESR rise and DC bus ripple — HEXIN electrolytic capacitors in VFD DC link degrade rapidly when equipment runs continuously in high ambient temperatures (45-50°C) common in Indian summer operations. Aging dielectric increases equivalent series resistance (ESR), reducing filtering and causing inverter instability.
- ✓MCU firmware corruption and control board boot failure — HEXIN PLC and HMI panels experience memory corruption when subjected to supply voltage surges during grid switching in Indian industrial estates, or when battery-backed SRAM backup circuits fail. Corrupted bootloader code prevents CPU initialization, causing total system hang.
- ✓Encoder signal loss and servo positioning error — HEXIN servo systems in Indian textile loom and CNC machinery experience encoder cable breakage from machine vibration, or incremental encoder LED degradation from temperature cycling. Loss of position feedback causes open-loop position error accumulation and loss of closed-loop torque control.
- ✓HMI touchscreen unresponsiveness and LCD backlight failure — HEXIN industrial HMI panels fail when capacitive touch controller IC solder joints crack due to thermal shock (summer heat to air-conditioned control room transitions), or when LCD CCFL/LED backlights degrade after 5-7 years continuous operation in Indian pharmaceutical and food processing plants.
- ✓RS485 communication bus noise and data frame errors — HEXIN fieldbus modules in Indian factories suffer EMI from VFD switching harmonics, unshielded cable runs alongside high-current motor leads, and improper termination resistors. Noise causes CRC errors and Modbus protocol timeouts, disrupting SCADA real-time data collection and alarm system responsiveness.

Frequently Asked Questions — HEXIN Repairs
Do you repair HEXIN equipment anywhere in India?+
Yes. Synchronics repairs the complete HEXIN industrial electronics range — VFDs, servo drives, PLCs, HMI touchpanels, soft starters, and communication modules across India. We offer PAN India scheduled pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Jaipur, Lucknow, and all tier-2/3 industrial cities. All repairs are processed at our Vadodara, Gujarat headquarters with 7-14 day turnaround for standard faults.
How do I identify which HEXIN VFD model I have, and can you source spare parts?+
HEXIN VFD model numbers are printed on the front nameplate (e.g., HX-VFD-7.5 indicates 7.5 kW three-phase). Synchronics maintains inventory of IGBT modules, capacitor banks, control board components, and firmware versions for all HEXIN drive series. If original parts are unavailable, we recommend equivalent-spec industrial-grade components rated for Indian industrial duty cycles and temperatures.
What is the typical repair cost for a HEXIN servo drive with encoder signal loss?+
HEXIN servo drive encoder faults typically cost Rs 3,500-8,500 depending on whether the issue is cabling/connector (low cost), encoder LED degradation (moderate), or servo loop board component replacement (higher). Synchronics provides free diagnostic assessment via phone/video consultation; you receive a detailed quote and repair timeline before work begins. Express service (48-hour turnaround) incurs 25% premium.
Can Synchronics repair HEXIN PLC programs or just hardware components?+
Synchronics handles both HEXIN PLC hardware repair and firmware recovery. If your HEXIN PLC has corrupted application code, we can reload it from your backup copies, or reverse-engineer ladder logic from field device behavior. We do not write new custom programs, but we restore your existing automation logic and test it against your original machine sequence specifications.
Are HEXIN spare parts and replacement boards still available in India?+
Direct HEXIN India spare parts availability is limited due to competition from newer brands. Synchronics sources genuine HEXIN replacements through authorized distributors and offers compatible industrial-grade substitutes (same electrical specifications, proven in field use) for discontinued modules. We always prioritize OEM parts first; equivalents are used only when unavailable and with your explicit approval.
How do I send my HEXIN 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 HEXIN 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 HEXIN 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 HEXIN 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.
