EAC Product Lines We Repair
Our engineers are trained on the full EAC product range. Below are the major product families we service.
EAC PowerDrive Series
Compact variable frequency drives designed for motor speed control and energy optimization in production lines. Common issues include capacitor degradation, IGBTs failing under thermal stress, and firmware corruption causing loss of communication.
EAC ServoControl Modules
Precision servo motor controllers for synchronized multi-axis positioning in textile, packaging, and automotive applications. Frequent failures involve encoder signal loss, power stage faults, and calibration drift after power surges.
EAC Industrial PLC Platform
Modular programmable logic controllers for process automation and batch control in pharmaceutical and chemical plants. Repair focus includes I/O card failures, memory corruption, and real-time clock module degradation.
EAC Power Supply Units
Industrial-grade DC and regulated AC power supplies for control circuits and instrumentation. Common defects include transformer core failures, rectifier bridge degradation, and output regulation drift.
EAC Automation Interface Cards
Digital and analog signal conditioning modules for plant-floor integration. Typical failures involve optocoupler burn-out, ADC linearity loss, and relay contact welding.
Why Choose Synchronics for EAC Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on EAC equipment.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 EAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EAC equipment arriving at our workshop.
- ✓PowerDrive IGBT stage thermal shutdown failure — Electrolytic capacitors in the power stage dry out over 5-7 years, reducing heat dissipation efficiency. Thermal sensors then trigger protective shutdown, cutting motor power without load control.
- ✓ServoControl encoder communication loss (Error E-04) — Vibration-induced connector loosening or corroded encoder interface pins are typical in Indian textile mills and automotive assembly plants. The encoder signal integrity degrades, causing position feedback failure.
- ✓IPC firmware corruption preventing boot-up — Power supply brownouts, static discharge during field maintenance, or corrupted SD card image uploads can corrupt the IPC boot loader. The unit remains stuck in initialization loop.
- ✓PSU output voltage drooping under load (regulation failure) — Aged voltage reference integrated circuits (TL431 or equivalents) drift beyond tolerance, or feedback resistor networks develop parasitic leakage. The output rail sags as load increases.
- ✓Automation Interface AIC optocoupler channel failure (stuck high or low) — Industrial environments with heavy inductive switching (solenoid valve control) inject dV/dt transients that degrade optocoupler LED lifetime. Cumulative degradation causes signal lock-up.
- ✓EAC drive watchdog timeout causing emergency stop trigger — Communication protocol timeouts between EAC drive and host PLC, caused by noisy industrial fieldbus (Modbus RTU or Profibus). Loss of heartbeat signal causes protective watchdog activation.

Frequently Asked Questions — EAC Repairs
Do you repair EAC equipment anywhere in India?+
Yes, Synchronics repairs the full EAC portfolio — PowerDrive frequency converters, ServoControl modules, Industrial PLC platforms, power supplies, and automation interface cards. We operate PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other industrial cities. All repairs are processed in our facility in Vadodara, Gujarat, with guaranteed 48-hour turnaround for non-availability spares.
What is the typical repair cost for an EAC PowerDrive or ServoControl module?+
Repair costs depend on fault severity and component replacement needs. Capacitor replacement or optocoupler fixes typically run Rs 8,000-15,000. Major power stage rebuilds (IGBT + rectifier + capacitor sets) range Rs 22,000-45,000. We provide free diagnosis and quote within 24 hours of receipt. Synchronics also offers refurbished EAC modules at 40-50% of new cost, fully tested and warranted for 12 months.
Can you repair EAC drives with corrupted firmware or memory errors?+
Yes. Synchronics holds EAC-licensed firmware images for all major product families including PowerDrive, IPC, and ServoControl series. We perform secure boot restoration, parameter recalibration, and full functional testing. If the bootloader is damaged, we use JTAG and ISP programming tools to restore the flash memory directly. Turnaround for firmware recovery is typically 36-48 hours.
Do EAC drives work with Indian industrial power quality standards?+
EAC drives are rated for 150-276V AC input (single-phase) and 200-400V AC (three-phase), compatible with Indian power grids. However, Indian manufacturing sites often experience voltage transients, harmonics, and neutral shift. Synchronics recommends installing 3-phase isolation transformers and harmonic filters ahead of EAC drives in areas with poor power quality. We also stock EAC-compatible EMC filters and surge suppressors for protection against DIN rail transients common in Indian industrial environments.
What warranty does Synchronics offer on EAC repairs?+
All EAC repairs carry a 12-month parts and labor warranty covering the repaired circuit or component. If the same fault recurs within warranty, we repair free of charge including courier costs. Extended 24-month warranty is available at an additional 15% of repair cost. For critical applications, Synchronics offers on-site warranty with emergency response SLA of 4 hours in major metro areas.
How do I send my EAC 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 EAC 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 EAC 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 EAC 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.
