GD Product Lines We Repair
Our engineers are trained on the full GD product range. Below are the major product families we service.
GD Frequency Drives (VFD/AC Drives)
Three-phase variable frequency drives for motor speed control and energy optimization. Common issues include capacitor degradation, IGBT module failure, control board faults, and firmware corruption affecting torque output and acceleration ramps.
GD Servo Drive Systems
Closed-loop servo controllers for precision positioning, velocity regulation, and coordinated multi-axis motion. Typical faults include encoder signal loss, current loop instability, hall sensor errors, and commutation timing drift.
GD PLC and Motion Controllers
Industrial programmable logic controllers and motion control units for factory automation and real-time process management. Common repair needs include memory corruption, I/O card failures, communication protocol errors, and backup battery replacement.
GD Soft Starters
Electronic motor starting devices providing reduced inrush current and smooth acceleration. Frequent issues involve thyristor module failure, cooling fan breakdown, thermal overload calibration drift, and power supply stage faults.
GD Regenerative Rectifier Units
Power conversion modules for energy recovery and bidirectional power flow in crane, elevator, and press applications. Common failures include diode bridge shorts, capacitor bank derating, gate drive circuit faults, and DC bus voltage regulation issues.
GD Communication Gateway Modules
Industrial Ethernet, Profinet, Modbus, and CANopen interface cards for networked drive systems. Typical repair work includes port damage, transceiver IC failure, protocol stack firmware updates, and isolation transformer breakdown.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GD equipment arriving at our workshop.
- ✓GD Drive Over-Temperature Shutdown During Load — Heatsink thermal paste degradation, cooling fan motor bearing seizure, or blocked air intake reducing convection. Ambient factory temperatures above 40°C accelerate thermal runaway in GD frequency drives.
- ✓GD IGBT Module Short Circuit or Gate-Drive Failure — Voltage spikes during motor braking, contaminated solder joints under thermal cycling, or defective gate driver IC causing phase-leg shoot-through conditions. Common in drives operating under heavy regenerative loads.
- ✓GD PLC Memory Corruption or Program Loss — Sudden power loss during firmware write cycle, defective EEPROM, or battery-backed RAM cell failure. Particularly occurs in facilities with unstable grid power or inadequate UPS protection.
- ✓GD Servo Drive Encoder Signal Loss or Phase Error — Damaged encoder connectors, broken optical encoder disc, noise on differential encoder lines, or phase mismatch between incremental channels. High vibration environments degrade hall sensor and encoder signal integrity.
- ✓GD Soft Starter Thyristor Module Open Circuit — Repetitive high inrush motor starting currents exceeding thyristor junction temperature limits, inadequate gate pulse width, or solder fatigue on power terminals. Old starters accumulating thermal stress are prone to this failure.
- ✓GD Communication Gateway Modbus/Profinet Timeout or Protocol Errors — Damaged RJ45 port pins, failed isolation transformer, defective transceiver IC, or corrupted firmware causing dropped packets. Industrial EMI and loose connectors compound protocol instability in Indian factory floors.

Frequently Asked Questions — GD Repairs
Do you repair GD equipment anywhere in India?+
Yes. Synchronics repairs the complete GD product portfolio — frequency drives, servo systems, PLCs, soft starters, regenerative modules, and communication gateways. We offer PAN-India door pickup from all major cities: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bengaluru, Kolkata, and beyond. All repairs are processed at our certified facility in Vadodara, Gujarat, with express turnaround options for critical production downtime.
How long does GD drive repair typically take at Synchronics?+
Standard GD frequency drive repairs are completed in 5-7 working days including diagnostics, component replacement, and full load testing. Complex servo system retuning or multi-module failures may require 10-12 days. Emergency same-day diagnostics are available for critical plant failures. We provide regular status updates and priority handling for major automotive, pharma, and textile OEMs across India.
Can Synchronics repair GD equipment with burnt or corroded circuit boards?+
Yes. Our engineers specialize in component-level board reconstruction for GD drives and controllers. We remove burnt components, replace corroded connectors, re-solder surface-mount ICs, and rebuild power traces using precision techniques. Accelerated aging and thermal cycling tests verify reliability. Most heavily damaged GD boards are restored to 95%+ functionality at 40-60% of replacement cost — critical for Indian OEMs facing long lead times and import tariffs.
What if my GD drive shows a fault code I cannot find in the manual?+
Synchronics engineers maintain comprehensive GD fault code databases covering all series and firmware versions. We decode undocumented error codes by analyzing drive behavior, measuring signal voltages, and reviewing parameter settings. Common issues like 'E1.5' encoder timeout or 'E3.2' IGBT desaturation faults are rapidly diagnosed via oscilloscope testing. Send the fault code, drive model, and operating conditions — we provide root-cause analysis and repair recommendation within 24 hours.
Does Synchronics offer GD drive parameter backup and restoration?+
Yes. Before repair, we extract and archive all drive parameters, PLC logic, servo tuning constants, and communication settings. After repair, we restore your exact configuration to avoid re-commissioning delays. We also document parameter deviations and provide optimization recommendations if your GD equipment was operating below specification. Critical for automotive OEMs and textile mills running synchronized multi-drive applications across India.
How do I send my GD 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 GD 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 GD 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 GD 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.
