Expert GMA servo drive and motion controller repair across all Indian industrial sectors.
GMA Product Lines We Repair
Our engineers are trained on the full GMA product range. Below are the major product families we service.
GMA Servo Drives
High-performance servo amplifiers for closed-loop motor control, vector drives for AC induction motors, and stepper/brushless motor controllers. Common issues include capacitor degradation, encoder signal loss, and firmware corruption affecting motion accuracy.
GMA Motion Controllers
Multi-axis interpolation and coordinated motion platforms. Repair focus includes I/O module failures, communication protocol breakdowns (CANopen, EtherCAT), and real-time kernel instability causing lost synchronization between axes.
GMA Inverter Modules
Compact frequency converters and regenerative drives for AC motor speed control. Typical faults: IGBT failures, DC bus ripple instability, thermal runaway in power stages, and phase imbalance detection errors.
GMA Encoder Interfaces
Incremental and absolute encoder signal conditioners with SSI, CANopen, and pulse output. Common problems: signal noise immunity loss, reference mark detection failure, and galvanic isolation breakdown.
GMA Terminal Controllers
Compact programmable logic controllers with analog input/output and Ethernet connectivity for standalone or networked automation. Faults include power supply regulation collapse, real-time clock drift, and SD card read/write errors.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GMA equipment arriving at our workshop.
- ✓Servo drive encoder communication loss — GMA servo drives lose SSI or CANopen encoder signal due to shielded cable degradation, connector corrosion, or signal conditioning module failure. This causes E-STOP or position error codes and loss of closed-loop control.
- ✓IGBT short-circuit and drive lockout — Power transistor failure in GMA inverter bridges, often triggered by overvoltage transients, short-circuit load conditions, or inadequate DC bus capacitor aging. Drive enters fault-safe state and refuses restart.
- ✓Motion controller synchronization drift — Multi-axis GMA controllers lose timing sync between coordinated axes due to real-time kernel instability, CAN message latency, or firmware corruption. Results in position offset and mechanical binding.
- ✓DC bus voltage collapse under load — GMA drive DC bus capacitors or rectifier stage fail, dropping bus voltage below minimum operating threshold. Drive throttles output or shuts down during acceleration, causing intermittent stalls.
- ✓Thermal runaway shutdown — GMA power stage temperature sensor fails or heat dissipation is blocked by dust/debris. Drive triggers emergency shutdown at low operating temperature or fails to trigger at high temperature, causing field inconsistency.
- ✓CANopen node address conflict and network failure — GMA controller or drive node loses CAN arbitration or is configured with duplicate node ID, blocking network communication and halting coordinated motion or data acquisition.

Frequently Asked Questions — GMA Repairs
Do you repair GMA equipment anywhere in India?+
Yes. Synchronics is the authorized GMA repair partner for all of India. We repair servo drives, motion controllers, inverters, encoder interfaces, and PLC terminals from our Vadodara facility. We offer free PAN India pickup from Mumbai, Delhi, Pune, Bangalore, Hyderabad, Chennai, Ahmedabad, and all other industrial cities. Average turnaround is 7-10 working days for most faults. Express 48-hour repair is available for critical production emergency shutdowns.
Can you repair GMA servo drives with firmware corruption?+
Yes. If a GMA servo drive has corrupted or lost firmware, we have access to verified firmware images for all GMA drive series. We reprogram EEPROM and flash memory using specialist GMA programming tools, test the restored drive on our servo test bench, and verify encoder feedback and motor control before shipment. This service costs significantly less than replacement and restores full functionality.
How do I know if my GMA drive capacitor bank needs replacement?+
GMA drive capacitors typically degrade after 8-12 years or fail prematurely under high ambient temperature or electrical stress. Signs include drooping DC bus voltage, thermal fuse trips, and intermittent drive shutdowns during load spikes. Synchronics conducts capacitance and ESR testing on every incoming GMA drive. If capacitors measure below 80% rated value or ESR is elevated, we replace the entire capacitor bank with industrial-grade extended-life units rated for 105 degrees Celsius.
What is the cost of GMA encoder interface repair versus replacement?+
GMA encoder signal modules (SSI, CANopen, or resolver converters) typically cost 15,000-35,000 INR new. Synchronics repairs them for 4,000-8,000 INR on average, including connector replacement, signal conditioning module swap, and full functional test. We repair 70% of incoming GMA encoder modules without requiring replacement, saving customers 60-70% versus new module cost.
Do you offer GMA drive calibration and commissioning after repair?+
Yes. After repairing any GMA servo drive or motion controller, we perform full calibration including encoder offset adjustment, motor parameter identification, load-bank tuning, and multi-axis synchronization testing if applicable. Our calibration report documents all settings and is provided to the customer. For textile machinery, printing presses, and precision positioning applications, this ensures the GMA drive performs exactly as it did before the fault.
How do I send my GMA 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 GMA 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 GMA 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 GMA 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.
