AEC Product Lines We Repair
Our engineers are trained on the full AEC product range. Below are the major product families we service.
AEC Drive Control Modules
AC and DC drive controllers with advanced motion profiling and real-time feedback loop compensation. Common faults include capacitor degradation in power stages, encoder signal loss, and gate driver failures under thermal stress in high-speed textile or packaging lines.
AEC Servo Motion Controllers
Closed-loop servo amplifiers for precision positioning in automated assembly, CNC, and robotic systems. Typical issues: position feedback circuit faults, servo loop instability, firmware corruption, and encoder connector oxidation in humid Indian factory environments.
AEC Logic Control Modules (PLC-style)
Compact programmable controllers for discrete automation and machine sequencing. Repair challenges include memory chip failure, I/O relay coil burnout, and communication protocol timeouts in noisy industrial RF environments.
AEC HMI and Fieldbus Interface Modules
Gateway modules for Modbus, EtherCAT, and PROFIBUS integration. Frequent faults: Ethernet transceiver damage, protocol stack crashes, and power supply dropout under line voltage fluctuations common in Indian industrial grids.
AEC Regenerative Braking and Power Conditioning Units
Energy recovery and harmonic filtering for multi-axis systems. Common issues: bulk capacitor ESR rise, IGBT thermal cycling cracks, and DC bus voltage sag during rapid deceleration cycles in heavy machinery.
AEC Encoder and Feedback Signal Conditioning
Precision amplifiers for encoder, resolver, and analog sensor interfaces. Typical faults: input protection diode failure, operational amplifier offset drift, and impedance mismatch on long shielded cable runs in multi-axis machinery.

Common AEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AEC equipment arriving at our workshop.
- ✓AEC Drive Capacitor Bank Voltage Sag and Ripple — Electrolytic capacitors in the main power stage degrade due to thermal cycling (ambient heat + internal switching losses). Typical in Indian textile mills and packaging lines running 12-16 hours daily, capacitor ESR rises and capacitance drops, causing unstable DC bus voltage and intermittent servo oscillation.
- ✓AEC Servo Loop Instability and Position Overshoot — Encoder feedback cable shielding degradation, connector pin corrosion, or firmware PID tuning drift. In humid Indian factory floors (textile, food processing), salt-laden air corrodes encoder connectors and causes intermittent signal dropout, triggering loop oscillation and mechanical jitter.
- ✓AEC Power Supply Crowbar Fault and Shutdown Lockup — Overvoltage crowbar circuit triggering due to supply spikes during grid power dips and recoveries, common in rural Indian manufacturing zones with unstable 3-phase supply. Failed TVS diodes or SCR gate drive issues prevent safe shutdown, forcing full module reset.
- ✓AEC Firmware Corruption and Boot Failure — Unexpected power cuts, improper module shutdown sequences, or EEPROM cell fatigue after many firmware updates. In Indian plants experiencing frequent load-shedding or blackouts, cumulative power-loss events corrupt the AEC controller's boot loader or application image, leaving the module non-responsive.
- ✓AEC Gate Driver Failure and PWM Output Loss — MOSFET or IGBT gate driver IC degradation due to thermal stress, inadequate heatsinking, or bootstrap capacitor leakage. High-speed servo drives in Indian automotive assembly lines experience continuous switching cycles; inadequate thermal management causes gate driver bias voltage to drift, leading to reduced gate drive current and intermittent PWM shutdown.
- ✓AEC I/O Relay Coil Burnout and Stuck Contacts — Inductive load transients from connected solenoids, motors, or contactor coils cause back-EMF spikes that damage relay drivers and contact welding. In Indian textile mills or packaging plants with poor cable management and long control runs, unshielded solenoid return paths dump energy back into the AEC logic module.

Frequently Asked Questions — AEC Repairs
Do you repair AEC equipment anywhere in India?+
Yes. Synchronics repairs the full AEC product range — drives, servo controllers, HMI gateways, encoder signal conditioning, and regenerative braking units. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are carried out at our main facility in Vadodara, Gujarat, with online tracking and technical consultation.
What is the typical turnaround time for AEC drive repair?+
Most AEC drive and servo module repairs complete within 5-7 working days, including component-level diagnostics, board repair or component replacement, full bench testing, and thermal characterisation. Expedited repair (2-3 days) is available for critical production lines; we also maintain a small stock of refurbished AEC units for emergency swap-outs while your device is in the repair queue.
Can Synchronics recover firmware from a corrupted AEC controller?+
Yes, absolutely. Synchronics specialises in EEPROM and flash memory recovery for AEC modules. We use JTAG programming interfaces and advanced chip-off techniques to extract firmware images, identify boot sector corruption, and re-flash the module with original or updated firmware versions. We also validate the recovered firmware against factory test suites to ensure seamless re-integration into your system.
Do you stock spare parts for AEC equipment, or only offer repair?+
Synchronics offers both comprehensive repair and selected spare component supply for AEC modules. We stock common failure items — capacitors, gate driver ICs, power relays, encoder connectors, and thermal interface materials — at our Vadodara facility. For long-lead imported components, we can source through our international vendor network and expedite delivery to Indian manufacturing sites.
How does Synchronics handle AEC servo tuning and commissioning after repair?+
After repairing AEC servo controllers, our engineers perform full closed-loop tuning using load emulation hardware and automated PID sweep algorithms. We deliver detailed servo performance reports — bandwidth, phase margin, overshoot, settling time — and provide remote commissioning support to integrate the repaired module back into your machinery. Many Indian OEMs trust us for pre-delivery servo validation before shipment to end customers.
How do I send my AEC 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 AEC 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 AEC 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 AEC 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.
