AET Product Lines We Repair
Our engineers are trained on the full AET product range. Below are the major product families we service.
AET AutoControl Series
Compact programmable logic controllers for mid-range manufacturing automation. Common issues include memory corruption in flash storage, communication module failures on Ethernet ports, and CPU overheating in high-ambient-temperature environments. Repair focuses on module replacement and firmware restoration.
AET PowerDrive Series
Vector-controlled frequency converters (0.75 kW to 315 kW) for three-phase motor drive applications. Failures typically involve IGBT module breakdown, capacitor bank degradation, and control board short circuits. Synchronics performs gate driver repair, power stage diagnostics, and thermal imaging analysis.
AET HMI TouchPro Series
Industrial touchscreen HMI panels with 4-inch to 10-inch displays for real-time process monitoring. Display backlight failures, resistive touchscreen calibration loss, and communication gateway malfunctions are typical repair cases. We replace LCD modules, reprogram firmware, and restore Modbus/Profibus connectivity.
AET ServoControl Module
Dedicated servo drive controllers for precision positioning in textile looms, packaging machinery, and CNC retrofits. Issues include encoder signal loss, PWM output stage failures, and 24V power supply malfunction. Our technicians recalibrate feedback loops and replace failed discrete components.
AET CommunicationGateway Series
Industrial protocol converters supporting Profibus DP, Profinet, CANopen, and legacy RS485 networks. Gateway software crashes, optical isolation relay failures, and termination resistor burnout are common issues. Repair includes firmware updates and redundant communication path testing.
AET PowerSupply Modular Range
24V DC industrial power supplies (5A to 100A) with redundancy modules for safety-critical applications. Failures stem from electrolytic capacitor aging, transformer core saturation, and output voltage regulation drift. Synchronics performs thermal stress testing and full load burn-in after repair.
Why Choose Synchronics for AET Repairs?

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 AET Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AET equipment arriving at our workshop.
- ✓AET AutoControl CPU memory parity error — Flash memory degradation due to power surge spikes during grid switching, or repeated firmware uploads exceeding cell cycle limits. Indian manufacturing environments with unstable power supply are particularly vulnerable.
- ✓AET PowerDrive IGBT module short circuit — Thermal cycling stress on power semiconductor junction, combined with contaminated cooling fins reducing heat dissipation in high-humidity textile mill environments. Gate drive circuit overvoltage spikes can trigger cascading failure.
- ✓AET HMI TouchPro backlight inverter failure — Capacitor electrolyte drying in high-temperature production areas (>45°C ambient), or high-voltage spikes from unshielded power cables running parallel to display ribbon cables in crowded control panels.
- ✓AET ServoControl encoder signal loss or noise — Loose RJ45 connector on encoder cable (common in high-vibration stamping or spindle applications), EMI coupling from nearby VFD cables, or encoder optical disk contamination from coolant spray in machining centers.
- ✓AET CommunicationGateway Profibus DP timeout errors — Misconfigured baud rate or address conflicts after network expansion, corrupted gateway firmware preventing proper token rotation, or defective termination resistors causing signal reflections on long cable runs (>400m) in large facility networks.
- ✓AET PowerSupply 24V output voltage drift under load — Transformer primary winding insulation breakdown due to moisture ingress in monsoon-heavy regions, or feedback network resistor value shift from thermal aging. Series-pass transistor bias network may fail in older PS-24/50 units.

Frequently Asked Questions — AET Repairs
Do you repair AET equipment anywhere in India?+
Yes. Synchronics repairs all AET product lines — AutoControl PLCs, PowerDrive frequency converters, HMI TouchPro panels, ServoControl modules, CommunicationGateway units, and PowerSupply ranges. We offer PAN-India door-to-door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major cities. All repairs are completed at our advanced facility in Vadodara, Gujarat, with TAT of 5-10 working days for standard faults and 3-5 days for critical breakdowns.
Can you repair AET AutoControl PLC firmware corruption without losing program data?+
Absolutely. Synchronics uses specialized non-destructive memory extraction techniques to backup your PLC program logic before any firmware operation. We restore the OEM baseline image, then reload your original application software. If your backup is unavailable, our engineers can often reverse-engineer program flow from flash dump analysis — common for legacy AutoControl AC-240 and AC-340 models. This preserves your production logic and minimizes commissioning time.
What is your turnaround time for AET PowerDrive frequency converter IGBT replacement?+
For standard IGBT module failure in PowerDrive PD-11, PD-22, and PD-45 units, our TAT is 7-9 working days including module replacement, gate-drive recalibration, and thermal cycling validation. For emergency breakdowns affecting critical production lines (textile mills, packaging plants), we offer 48-hour express service with nominal rush charge. Critical automotive and pharmaceutical clients often maintain spare module sets with Synchronics for rapid hot-swap capability.
Do you provide AET spare parts or only repair services?+
Synchronics primarily specializes in repair and remanufacturing of AET modules and assemblies. However, we maintain stock of high-failure components — IGBT modules, capacitor banks, display panels, encoder cables, and transformer assemblies — for common AET units. We also source OEM spare parts through our European supplier network. Contact our spare parts desk for availability and lead time; Indian manufacturing clients often prefer repair-to-like-new over costly new equipment replacement.
How do I know if my AET equipment requires repair or simple troubleshooting?+
Call our technical helpline with fault symptoms, error codes (if displayed), and equipment model number. Our AET specialists can often diagnose over-the-phone — many issues are configuration, parameter, or loose connector problems. If in-depth diagnosis is needed, we offer free bench inspection for equipment sent to Vadodara, typically completed within 48 hours. We provide written diagnostic report with repair recommendation and cost estimate before proceeding.
How do I send my AET 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 AET 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 AET 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 AET 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.
