Synchronics specialises in G-D Electric drive repair, soft starter troubleshooting, and control panel diagnostics across Indian manufacturing facilities.
G-D ELECTRIC Product Lines We Repair
Our engineers are trained on the full G-D ELECTRIC product range. Below are the major product families we service.
G-D DC Drives (GD-VFD and GD-DC Series)
Variable frequency DC drives used extensively in sugar processing, textile spinning, and paper manufacturing. Common faults include thyristor firing failures, loss of field regulation, and brake chopper malfunctions requiring specialist knowledge of G-D's gate drive circuits.
G-D Soft Starters (GD-Softstarter Range)
Three-phase soft starting controllers for reducing inrush current in centrifugal pumps, fans, and compressors. Typical issues include power module thermal shutdown, zero-crossing detection failure, and current limiting circuit malfunction.
G-D PFC Panels (Power Factor Correction)
Automatic capacitor bank switching systems for reducing reactive power in mills and factories. Failures often stem from contactor wear, relay malfunction, microcontroller programming loss, or capacitor element degradation.
G-D Control Panels and Operator Interfaces
Customised industrial control enclosures with integrated PLCs, HMI touchscreens, and relay logic. Repairs involve troubleshooting communication loss, touchscreen display faults, sensor input failures, and firmware corruption.
G-D Brake Choppers and Regenerative Modules
Dynamic braking resistors and regenerative converter modules for dissipating kinetic energy during motor deceleration. Common faults include resistor element burnout, gate driver IC failure, and IGBT short-circuit.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common G-D ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in G-D ELECTRIC equipment arriving at our workshop.
- ✓G-D DC Drive loss of field regulation — Field winding excitation failure in compound-wound motors or loss of feedback signal from G-D's proprietary field sensor. Common in high-humidity environments where sensor connectors corrode.
- ✓G-D Soft Starter zero-crossing detection failure — Capacitive sensing circuit degradation or phase sequence detection IC malfunction in G-D soft starters exposed to voltage transients from heavy industrial loads or poor power quality common in Indian grid conditions.
- ✓G-D PFC Panel capacitor bank thermal runaway — Aluminium electrolytic capacitor ripple current stress from harmonic distortion typical in textile mills and cement plants, causing internal resistance rise and self-heating until dielectric failure.
- ✓G-D Control Panel HMI touchscreen unresponsive display — Firmware corruption, CRC error, or communication protocol breakdown between G-D microcontroller and display module — often triggered by supply voltage glitches or lightning proximity strikes common in open-cast mining and cement plants.
- ✓G-D Brake Chopper resistor element burnout during emergency stop — Undersized braking resistor or contactor welding during rapid deceleration cycles in sugar mill crushers and steel rolling mill uncoilers, causing resistor current to exceed rated limits and thermal element fusion.
- ✓G-D Drive IGBT power module short-circuit and gate driver collapse — Desaturation of IGBT junction due to excessive junction temperature or gate oxide strain from voltage transients. High ambient temperatures in Indian foundries and forges aggravate thermal stress on G-D power modules.

Frequently Asked Questions — G-D ELECTRIC Repairs
Do you repair G-D Electric equipment anywhere in India?+
Yes. Synchronics repairs the full G-D Electric product range — DC drives, soft starters, PFC panels, control systems, and brake choppers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Surat, and all other industrial cities. All repairs are conducted in our certified Vadodara, Gujarat facility by engineers trained on G-D Electric systems.
What is the typical turnaround time for G-D Electric soft starter repair?+
Routine G-D soft starter faults like zero-crossing detection failure or contactor wear are repaired within 3-5 working days. Complex repairs requiring custom gate driver reprogramming or power module replacement extend to 7-10 days. Synchronics maintains spare G-D compatible components in stock to minimise delay. Express service available for critical production shutdowns.
How do I know if my G-D Electric DC drive has a thyristor firing circuit fault?+
Common signs include motor not accelerating beyond 30-40% speed, audible commutation noise, or slow speed regulation drift under load. G-D drives display commutation error codes on connected HMI displays. Synchronics diagnoses thyristor firing faults using dual-channel oscilloscope analysis of gate trigger pulses and gate cathode return paths. We test repaired drives on live motor load before dispatch.
Can Synchronics upgrade old G-D Electric control panels to modern HMI systems?+
Yes. Synchronics retrofits legacy G-D control panels with modern touchscreen HMI interfaces while preserving existing motor protection and sensor input configurations. We reprogram logic algorithms to match original G-D panel functionality and conduct extensive compatibility testing. Retrofit cost is typically 40-50% lower than complete panel replacement for sugar mills, textile spinners, and cement plants.
What warranty do you provide on G-D Electric repair work?+
All G-D Electric repairs carry 12 months comprehensive warranty covering parts and labour against manufacturing defects and workmanship failure. We provide 24-month limited warranty on power modules, capacitors, and IGBT components. Synchronics issues detailed repair certificates documenting all components replaced and test results for compliance documentation and insurance purposes.
How do I send my G-D ELECTRIC 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 G-D ELECTRIC 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 G-D ELECTRIC 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 G-D ELECTRIC 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.
