CEI Product Lines We Repair
Our engineers are trained on the full CEI product range. Below are the major product families we service.
CEI FlexDrive Series
Programmable AC and DC motor drives designed for precision speed control and load matching. Common failures include power stage faults, control board capacitor failures, and firmware corruption. Repair requires specialized programming and IGBT testing capability.
CEI MotionPro Controllers
Multi-axis motion control platforms for coordinated machine tool and robotic applications. Typical issues include servo feedback signal loss, timing pulse errors, and communication port failures. Our technicians perform board-level component replacement and servo tuning calibration.
CEI PowerModule Series
Dedicated power conditioning and isolation modules for sensitive industrial loads. Common faults include thermal management failure, transformer winding shorts, and capacitor bank degradation. Repair involves transformer testing, thermal imaging diagnostics, and component replacement.
CEI ServoDrive Plus
High-performance servo amplifiers for precision positioning and continuous-duty applications in textile, packaging, and semiconductor manufacturing. Typical failures: encoder interface faults, current sensing circuit failures, and firmware version incompatibilities affecting Indian legacy machinery.
CEI IPC Industrial Control Boards
Embedded industrial PC modules and DSP-based control cards used in machine automation and process control systems. Common repair items include RAM module failures, real-time clock circuit issues, and flash memory re-programming for corrupted bootloaders.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CEI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CEI equipment arriving at our workshop.
- ✓CEI drive power stage IGBT short circuit — Thermal cycling stress from India's hot industrial environments combined with capacitor ripple current buildup causes IGBT gate oxide breakdown and short-circuit failure, often accompanied by smoke and smell.
- ✓CEI motion controller communication timeout errors — Intermittent cable connections between CEI controller and servo/motor feedback devices, combined with high electromagnetic interference in Indian manufacturing plants using unshielded cabling.
- ✓CEI PowerModule transformer saturation and overheating — Sustained load imbalance and harmonic distortion from non-linear loads (VFDs, switching power supplies) in Indian textile and chemical plants cause core saturation, excessive winding current, and insulation breakdown.
- ✓CEI servo drive encoder signal loss fault code — Dust accumulation and moisture ingress in encoder connectors from open factory floors are common in Indian packaging and food processing plants. Corrosion of encoder interface pins prevents signal detection.
- ✓CEI control board capacitor electrolyte leakage — Extended ambient temperatures (40-45°C) in uncontrolled Indian plant environments accelerate electrolyte evaporation in aluminum electrolytic capacitors, causing capacitance loss and circuit instability.
- ✓CEI firmware corruption or bootloader failure — Unexpected power losses during system startup, voltage spikes from poor plant electrical infrastructure, and unauthorized firmware updates cause flash memory corruption in CEI embedded controllers.

Frequently Asked Questions — CEI Repairs
Do you repair CEI equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete CEI product range across India — drives, motion controllers, power modules, servo amplifiers, and industrial control boards. We operate from Vadodara, Gujarat with pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other major industrial cities. Express courier service available for urgent repairs.
What is the typical repair turnaround time for CEI drives?+
Standard CEI drive repairs take 5-7 working days including diagnostics, component replacement, testing, and quality verification. Express service available for critical production equipment (2-3 days). Turnaround depends on parts availability and complexity of failure. We maintain stock of common CEI replacement modules and capacitor banks to accelerate repairs.
Can you reprogram or upgrade CEI firmware and bootloaders?+
Absolutely. Synchronics has licensed CEI firmware programming tools and technical documentation. We can reload original firmware, perform bootloader recovery, and test firmware version compatibility with your hardware. If your CEI controller has corrupted flash memory or experienced unexpected shutdown during startup, we can recover it through EEPROM re-flashing.
Do you offer warranty on CEI repair work?+
Yes. All Synchronics CEI repairs come with 12-month parts warranty and 3-month labor warranty covering the specific fault repaired. We perform 100-hour burn-in testing on all drives and motion controllers before return. If the same fault recurs within warranty period, we repair or replace at no charge.
What is the cost of CEI drive repair versus replacement?+
CEI repair costs typically range from Rs. 8,000 to Rs. 35,000 depending on failure type and component replacement needs. New CEI drives cost Rs. 50,000 to Rs. 2,50,000+. Repair saves 40-70% compared to new equipment while maintaining original performance. Synchronics provides detailed quotation after diagnostics — no hidden charges.
How do I send my CEI 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 CEI 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 CEI 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 CEI 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.
