COMEXI Product Lines We Repair
Our engineers are trained on the full COMEXI product range. Below are the major product families we service.
COMEXI Servo Motor Controllers & Drives
High-precision servo positioning systems used in COMEXI flexographic presses for registration, tension control, and web handling. Common faults include servo loop instability, encoder signal loss, and firmware corruption leading to registration drift and print misalignment.
COMEXI PLC & Logic Control Modules
Industrial programmable controllers managing COMEXI laminating, slitting, and converting line automation. Frequent issues include input/output relay failures, memory module corruption, and communication bus errors causing machine lockups or partial function loss.
COMEXI HMI Touchscreen & Operator Panels
Industrial-grade human-machine interfaces controlling COMEXI line parameters, speed settings, and fault diagnostics. Common problems include touchscreen unresponsiveness, display backlight failure, SD card read errors, and communication protocol drops with main PLC.
COMEXI Encoder & Sensor Systems
Precision rotary and linear transducers for COMEXI web tension, speed, and position feedback. Typical failures include encoder connector corrosion in humid packaging environments, signal noise interference, and mechanical shaft bearing wear affecting registration accuracy.
COMEXI Power Supply Modules
Regulated DC and AC power conditioning units supplying COMEXI servo drives, logic controls, and sensor networks. Failure modes include capacitor degradation, thermal shutdown under load, ground faults, and output voltage regulation loss causing erratic machine behavior.

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 COMEXI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMEXI equipment arriving at our workshop.
- ✓Servo positioning error - registration drift — COMEXI servo encoder signals degraded by humidity or vibration in printing halls, or servo tuning parameters corrupted in controller memory. Common in 3-5 year old installations where seal degradation allows moisture ingress into encoder connectors.
- ✓HMI touchpanel backlight failure - no display visibility — COMEXI HMI panels use LED or CCFL backlighting that degrades after 2-3 years of continuous operation in warm production environments. Electrolytic capacitors in the backlight driver circuit also fail, preventing power delivery to the display.
- ✓PLC logic program memory corruption - machine halted — COMEXI PLC modules experience memory errors from power spikes during grid fluctuations common in rural Indian industrial zones, or from improper hot-swap of I/O modules. Battery-backed RAM modules fail without warning, losing production recipes and calibration data.
- ✓Stepper motor driver overheating - thermal shutdown during print run — COMEXI stepper drivers in slitting units overheat due to heatsink dust accumulation, failed cooling fans, or thermal paste drying out. High ambient temperatures in unventilated packaging facilities accelerate component aging and thermal sensor sensitivity drift.
- ✓Proximity sensor intermittent switching - production counting errors — COMEXI inductive and capacitive sensors mounted on laminating or slitting units fail due to accumulated packaging debris, humidity corrosion of sensing surfaces, or loose connector pins vibrating in the sensor housing from machine vibration.
- ✓Power supply output voltage unstable - intermittent machine faults — COMEXI multi-output power supplies fail when input AC mains are unstable (common in Indian industrial areas), or when electrolytic capacitors dry out from years of thermal cycling. Ground faults in the PCB or output traces cause voltage collapse under load.

Frequently Asked Questions — COMEXI Repairs
Do you repair COMEXI equipment anywhere in India?+
Yes. Synchronics repairs the full COMEXI product range — servo drives, PLC modules, HMI touchpanels, stepper controllers, sensors, and power supplies. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Surat, and all other cities. All repairs happen at our ISO 9001 certified facility in Vadodara, Gujarat, with 180+ industrial electronics engineers on staff.
What is the typical turnaround time for COMEXI servo drive repair?+
COMEXI servo drive repairs typically take 5-7 working days. This includes encoder signal verification, servo tuning calibration, load testing, and firmware validation. For urgent production stoppages, Synchronics offers express 48-hour turnaround and can dispatch loaner drives while your unit is being repaired, minimizing downtime in high-speed packaging lines.
Can you repair COMEXI PLC modules with corrupted production recipes?+
Yes. Synchronics has experience recovering COMEXI PLC program data from corrupted flash memory. If you have backup copies of your production recipes or calibration settings, we restore them after hardware repair. If backups don't exist, we can rebuild basic logic sequences based on your production requirements and machine specifications. We recommend all customers maintain offsite backups of their COMEXI automation programs.
Do you stock COMEXI spare parts or replacement modules?+
Synchronics focuses on field repair of COMEXI electronics rather than parts inventory. However, for components like encoder connectors, thermal paste, capacitors, and standard industrial sensors used in COMEXI equipment, we source compatible high-quality replacements. For proprietary COMEXI modules, we coordinate directly with authorized COMEXI distributors in India or source from stock held at COMEXI's service centers in Bangalore and Mumbai.
How do I know if my COMEXI packaging line has a servo or PLC fault?+
Common signs include registration errors (misaligned prints), touchpanel not responding to inputs, unexpected thermal shutdowns during production, and error codes on the HMI display. Synchronics offers remote diagnostics — send clear photos of error messages or describe machine behavior, and our engineers can advise whether the fault is electrical or mechanical. For suspected servo issues, we can arrange on-site oscilloscope testing of feedback signals to confirm before removing equipment.
How do I send my COMEXI 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 COMEXI 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 COMEXI 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 COMEXI 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.
