GGT Product Lines We Repair
Our engineers are trained on the full GGT product range. Below are the major product families we service.
GGT Frequency Inverters (3-phase AC drives)
Three-phase variable frequency drives for motor control in textile spinning, pump stations, and compressor applications. Common issues include capacitor degradation in humid Indian climates, IGBT module thermal runaway, and firmware corruption from voltage spikes.
GGT Control Modules (Programmable Logic)
Modular PLC-style controllers for sequential machine operation and safety interlocking. Repair focus includes memory backup battery failure, relay coil burnout, and input/output terminal corrosion from moisture ingress in mills and food plants.
GGT Power Supply Units (Industrial-grade PSUs)
24V DC and 48V DC regulated supplies for field devices, sensors, and control circuits. Failure modes include transformer winding short-circuit, rectifier bridge failure, and capacitor bank degradation under continuous thermal stress.
GGT Servo Driver Boards (Motion control electronics)
Closed-loop servo control electronics for precision positioning in textile looms, packaging machines, and CNC applications. Common faults: encoder input circuit failure, PWM driver transistor breakdown, and calibration drift requiring factory re-tuning.
GGT Soft-Start Controllers (Motor acceleration management)
Three-phase soft-starters reducing inrush current in large pump and fan motors. Repair includes thyristor and gate-drive circuit restoration, thermal sensor replacement, and control voltage stabilisation for fluctuating Indian grid conditions.

Common GGT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GGT equipment arriving at our workshop.
- ✓Frequency inverter tripping on DC bus overvoltage fault — GGT drives are sensitive to supply-side voltage transients common in Indian industrial zones. Regenerative energy from braking motors during emergency stops exceeds the inverter's internal clamp voltage, triggering the OVF (overvoltage fault) code and locking the drive into thermal shutdown.
- ✓Control module memory loss - all program data erased — GGT CM-series controllers rely on a small backup battery to retain EEPROM during power-off. In Indian heat and humidity, these Sanyo or Panasonic cells degrade after 10-12 years, losing charge and allowing memory cells to flip. Once detected, the module blocks start-up to prevent corrupt code execution.
- ✓Power supply unit output voltage sagging under load — GGT PSU24 and PSU48 units develop internal transformer winding faults or secondary rectifier bridge diode degradation, especially in textile mills with dusty, high-ambient environments. Output sag causes logic-level devices to behave erratically, triggering false sensor reads and machine lockups.
- ✓Servo driver encoder communication error - position feedback lost — GGT servo driver boards use differential encoder inputs (5V TTL or 10V analog feedback). Shielded cable degradation, connector corrosion, or EMI from adjacent inverters in packed control cabinets corrupt the encoder signal. Loss of feedback causes immediate servo shutdown and potential web breakage in textile looms.
- ✓Soft-starter thyristor gate-drive malfunction - motor does not accelerate smoothly — GGT soft-starters in pump and fan applications develop faults in the gate-drive transformer and opto-coupler circuits, especially under high inrush currents (>300A) during cold-start conditions. Gate pulse timing distortion prevents smooth torque ramping and stalls the motor mid-acceleration.
- ✓Inverter firmware corruption after power surge - stuck at boot screen — Lightning strikes and utility grid faults in India can induce voltage transients that corrupt the flash memory in GGT VF-series inverters. The device enters a boot-loop, unable to load its control firmware, and remains inoperable until the memory is restored and re-programmed.

Frequently Asked Questions — GGT Repairs
Do you repair GGT equipment anywhere in India?+
Yes. Synchronics repairs the full GGT product range across all Indian states — frequency inverters, control modules, power supplies, servo drivers, and soft-starters. We operate door-to-door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and 50+ other Indian cities. All repairs are performed at our main facility in Vadodara, Gujarat. Typical turnaround is 5-8 working days.
What is the typical repair cost for a GGT VF-series frequency inverter?+
GGT inverter repair costs range from INR 8,000 to 45,000 depending on the failure. A simple IGBT module replacement or capacitor bank refurbishment costs INR 8,000-15,000. Complex faults (firmware corruption, transformer short-circuit, or multiple board failures) range INR 25,000-45,000. Synchronics provides a free diagnostic assessment and quotation before any work begins. Warranty covers 12 months parts and labour.
Can you recover my GGT control module program if the memory is corrupted?+
In many cases, yes. If your original logic was archived on a PC or USB backup, Synchronics can reload it directly after memory repair. If no backup exists, our engineers can recover partial or full code from the EEPROM cells using specialised extraction tools, provided the chip is not physically damaged. We recommend all customers maintain annual firmware backups — ask us about our data archival service.
Do GGT drives work with non-GGT motors, or must I use GGT servo motors?+
GGT frequency inverters and soft-starters are motor-agnostic — they work with any standard 3-phase AC induction or servo motor of matching power and voltage rating. However, GGT servo drives (SD-series) are optimised for encoder feedback from GGT or compatible encoder-equipped motors. During repair, Synchronics tests your inverter with industry-standard motors to confirm full compatibility before re-delivery. Always confirm motor nameplate voltage and Hz rating match your inverter.
What is the warranty on repaired GGT equipment, and do you offer extended coverage?+
All Synchronics repairs come with a standard 12-month parts and labour warranty on the replaced component and any labour performed. Extended 24-month and 36-month warranties are available at an additional cost (typically 15-25% of repair price). We also offer preventive maintenance contracts for high-criticality GGT drives in 24/7 plants — annual inspections, firmware updates, and priority repair slots. Ask our service team for customised SLA options.
How do I send my GGT 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 GGT 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 GGT 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 GGT 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.
