GNC Product Lines We Repair
Our engineers are trained on the full GNC product range. Below are the major product families we service.
GNC Servo Amplifiers and Drives
Precision servo amplifiers controlling stepper and brushless motors in automation systems. Common issues include thermal runaway, encoder communication faults, and PWM output failures requiring board-level diagnostics and component replacement.
GNC Motion Control Modules
Programmable motion controllers managing multi-axis coordinated positioning and velocity profiles. Failures include FPGA logic errors, real-time clock drift, memory corruption, and fieldbus communication breakdowns that demand micro-code analysis.
GNC Programmable Logic Controllers (PLCs)
Modular PLC systems for industrial control with analog/digital I/O, communication modules, and data logging. Repair addresses input card failures, power supply faults, relay contact burnout, and firmware corruption in harsh factory environments.
GNC Stepper Motor Drivers
Microstepping drivers for NEMA and IEC frame stepper motors in textile, packaging, and CNC machinery. Common failures include H-bridge transistor breakdown, phase detection errors, and inadequate heat sinking causing loss of torque.
GNC Human-Machine Interfaces (HMIs)
Industrial touchscreen and keypad terminals for real-time process monitoring and operator control. Typical repairs involve LCD backlight failure, touchscreen calibration loss, communication protocol errors, and embedded OS crashes.
GNC Electromechanical Relays and Contactors
Heavy-duty industrial relays, contactors, and timer modules for motor control and load switching. Failures stem from contact erosion, coil burnout, mechanical jamming, and insulation breakdown requiring full module replacement or contact refurbishment.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GNC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GNC equipment arriving at our workshop.
- ✓GNC Servo Amplifier Thermal Shutdown — Inadequate heatsinking, prolonged full-load operation, or blocked cooling vents on the amplifier chassis. Thermal sensors trigger protection cutoff, halting axis motion and causing production stoppages in continuous manufacturing lines.
- ✓GNC Encoder Communication Failure — Shielded cable degradation, loose connectors, or corrupted encoder firmware in absolute position feedback systems. Loss of encoder signal causes servo loop to open, resulting in position error codes and motor stall conditions.
- ✓GNC PLC Memory Corruption — Power surges, incomplete firmware uploads, or corrupted SD/flash memory cards during program transfers. Data loss in program storage or SRAM causes unpredictable logic execution, halting production sequences and damaging machine state.
- ✓GNC Motor Driver H-Bridge Transistor Failure — Overcurrent from motor jam or phase-to-phase short circuit, or gate drive circuit malfunction causing shoot-through. Transistor junction breakdown causes complete phase loss and inability to generate motor torque in stepper or brushless applications.
- ✓GNC HMI Touchscreen Calibration Loss — Electrostatic discharge, prolonged humidity exposure, or corrupted touch controller firmware in humid Indian manufacturing environments. Users experience inability to accurately interact with interface buttons or coordinate misalignment across display regions.
- ✓GNC Contactor Coil Open Circuit — Thermal burnout from sustained high inrush current, insulation breakdown due to moisture ingress, or mechanical fatigue from excessive switching cycles. Contactor fails to energize, leaving motor circuits de-energized and halting driven equipment.

Frequently Asked Questions — GNC Repairs
Do you repair GNC equipment anywhere in India?+
Yes, Synchronics repairs the full GNC product range including servo drives, motion controllers, PLCs, stepper motor drivers, HMIs, and relay modules. We offer PAN India door pickup from all major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, Kolkata, and smaller manufacturing centers. All repairs are conducted at our facility in Vadodara, Gujarat with same-day acknowledgment and weekly status updates.
What is the typical repair turnaround for GNC servo amplifiers?+
Standard GNC servo amplifier repairs take 5-7 working days including diagnostics, component sourcing, board-level repair, and functional testing on loaded circuits. Rush repairs are available within 2-3 days for critical production lines. We provide loaner units for extended lead-time component replacements, ensuring minimal downtime for your manufacturing operation.
Can Synchronics reprogram or update GNC PLC firmware?+
Yes, we provide firmware reprogramming, configuration updates, and backup extraction for all GNC PLC models. Our technicians access GNC development tools, verify code compatibility with your hardware revision, and test logic execution against production cycle profiles. We also assist with logic troubleshooting and code optimization to improve cycle times on Indian industrial installations.
Do you stock spare parts for GNC motion control modules?+
Synchronics maintains a limited stock of critical GNC components including stepper motor H-bridge transistors, relay coils, thermal sensors, and connector assemblies. For longer lead-time parts, we coordinate directly with authorized GNC distributors and expedite shipping to your facility. We also repair and refurbish contactors, relays, and power boards in-house to reduce repair costs by 30-40% versus new replacements.
How do I know if my GNC equipment is beyond repair?+
Synchronics evaluates repair viability based on fault severity, component availability, and cost-benefit analysis compared to replacement. We provide transparent repair quotes with expected downtime and success probability. Typically, GNC servo amplifiers, motion controllers, and PLCs are repairable unless core CPU or power supply components are compromised. We advise on end-of-life considerations and support technology upgrades to newer GNC models when economically justified.
How do I send my GNC 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 GNC 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 GNC 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 GNC 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.
