G-TECH Equipment We Repair — By Category
G-TECH Product Lines We Repair
Our engineers are trained on the full G-TECH product range. Below are the major product families we service.
G-TECH GSeries Servo Drives
Compact 400W to 2kW AC servo drives with integrated motion control. Common failures include encoder interface faults, capacitor dry-out on 5V bias rails, and PWM module burnout under transient load spikes.
G-TECH SMC Motion Controller
Standalone 2-axis to 8-axis motion controller with Ethernet and USB interface. Prone to SD card corruption, parameter memory loss, and firmware corruption from power anomalies common in Indian industrial environments.
G-TECH Stepper Driver Modules
Microstepping drivers for NEMA23/34 stepper motors with 24VDC input. Failure modes include H-bridge MOSFET burnout, direction pin latch-up, and thermal runaway from blocked motor conditions.
G-TECH IO Expansion Boards
16-channel and 32-channel digital IO modules with opto-isolation and relay outputs. Common issues: relay coil open circuit, opto-coupler degradation, and 24VDC supply filtering defects.
G-TECH Communication Interface Cards
CANbus, Modbus RTU, and Ethernet adapter modules for legacy machinery integration. Failure includes isolation transformer breakdown, RS485 transceiver short-circuit, and protocol timeout errors.

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-TECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in G-TECH equipment arriving at our workshop.
- ✓G-TECH servo drive boot loop and watchdog reset — EEPROM parameter corruption from sudden power loss or firmware flash interruption. Common in plants with unstable 3-phase supply or faulty UPS systems in Indian factories.
- ✓Encoder feedback signal loss (E001 error) — Broken encoder cable shield, shorted encoder 5V rail capacitors, or worn brush contacts in rotary encoders after 5-7 years of continuous duty. Dust contamination is severe in Indian textile and cement plants.
- ✓Power stage IGBT or MOSFET burnout with overcurrent fault — Shorted motor winding, transient voltage spike during contactor switching, or inadequate snubber networks. Voltage spikes exceeding 800V are common when servo motors are suddenly disconnected while powered, typical in Indian machine shops.
- ✓SMC motion controller parameter loss after power cycle — Corrupted NVRAM or defective battery-backed real-time clock (RTC). Indian manufacturing plants often experience extended blackouts that deplete backup batteries faster than expected.
- ✓G-TECH drive unable to enable or soft fault E004 (control logic failure) — Corrupted firmware in secondary flash bank, failed control processor (DSP), or watchdog timer latch-up from noise immunity issues. Poor EMI shielding in packaging and textile machinery causes repeated noise injection.
- ✓Stepper driver stalled or lost step accumulation fault — H-bridge MOSFET degradation causing weak phase current, mechanical jam in ball screw, or microstepping resolution mismatch in SMC configuration. Common in Indian CNC tool changers and pick-and-place machinery under high-speed duty.

Frequently Asked Questions — G-TECH Repairs
Do you repair G-TECH equipment anywhere in India?+
Yes. Synchronics is the largest independent G-TECH repair center in India with authorized service points in Vadodara (headquarters), Mumbai, Pune, Delhi, Bangalore, Hyderabad, and Chennai. We offer PAN-India door-to-door pickup and same-week turnaround for servo drives and motion controllers. All repairs include 12-month warranty and technical support.
What is the typical repair cost for a G-TECH GSeries servo drive vs. OEM replacement?+
G-TECH GSeries servo drives cost INR 45,000-90,000 new from OEM distributors. Synchronics repairs cost INR 18,000-35,000 depending on fault severity — typically 50-60% savings. We provide upfront diagnostic reports and transparent pricing. Most customers recover repair cost investment within 3-4 months of downtime avoidance.
Can Synchronics recover parameters and settings from a dead G-TECH SMC controller?+
Yes. If the EEPROM chip is not physically damaged, our engineers can extract parameter data via JTAG or USB bootloader interface, even if the controller won't boot. We've successfully recovered custom motion profiles for Indian textile machinery and CNC centers. Recovery success rate exceeds 85% unless the SD card is mechanically broken.
How do I know if my G-TECH drive needs repair or just a firmware update?+
Fault codes E001-E006 often resolve with firmware reflash (DIY option). However, E004, E007, and boot-loop faults require hardware testing. Send your drive's error log to our technical team via email or WhatsApp — we provide free diagnostic guidance and recommend repair vs. firmware update based on symptoms. Most Indian plants cannot afford trial-and-error firmware experiments.
Does Synchronics offer preventive maintenance contracts for G-TECH machinery?+
Yes. We offer predictive maintenance packages for high-value G-TECH servo systems in automotive and packaging plants. Annual contracts (INR 25,000-50,000) include biannual health checks, firmware updates, encoder calibration, and 24-hour emergency support. Many Indian Tier-1 suppliers have reduced unplanned downtime by 35% using our maintenance plans.
How do I send my G-TECH 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-TECH 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-TECH 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-TECH 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.
