EL Product Lines We Repair
Our engineers are trained on the full EL product range. Below are the major product families we service.
EL COMMANDER Series AC Drives
Three-phase variable frequency drives for pump, fan, and compressor applications. Common faults include capacitor bank failures, IGBT thermal runaway, and Modbus communication dropout. Synchronics diagnoses power stage degradation and replaces components to OEM specs.
EL LOGIC PLC Controllers
Compact and modular PLCs for discrete automation and process control. Prone to memory corruption, EEPROM write failures, and real-time clock drift. Our technicians perform firmware restoration, module diagnostics, and field calibration.
EL PROSERVO Motion Amplifiers
Servo amplifiers for precision positioning and closed-loop motion control in textile and packaging machinery. Issues include encoder signal noise immunity, current loop instability, and hall sensor faults. Synchronics uses real-time oscilloscope analysis for tuning.
EL iO Terminal I/O Modules
Distributed I/O terminals with PROFINET and CANopen interfaces for modular automation. Common failures include relay contact welding, analog isolation breakdown, and communication node timeouts. Synchronics performs node re-enumeration and module replacement.
EL FLEXBUS Fieldbus Gateways
Multi-protocol gateways (PROFIBUS to Ethernet, CANopen conversion). Failures stem from protocol stack corruption, PHY chip thermal stress, and routing table overflow. Synchronics rebuilds communication stacks and replaces network interfaces.
Why Choose Synchronics for EL 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 EL equipment.
Fast Turnaround
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 EL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EL equipment arriving at our workshop.
- ✓Drive no-load output voltage instability — EL COMMANDER drives exhibit capacitive output filtering drift when DC bus electrolytic caps age. Voltage ripple increases, causing PLC read errors and encoder jitter in closed-loop systems.
- ✓PLC real-time clock losing sync after power cycle — EL LOGIC controllers' CMOS backup battery depletes prematurely due to internal leakage current. RTC drift causes timestamp errors in batch traceability logs and process recipe sequencing.
- ✓Servo amplifier following error exceeds ±0.5° threshold — EL PROSERVO encoder cables in high-vibration textile looms suffer shielding degradation, introducing differential-mode noise into the quadrature decoder. Loop gain tuning drifts with motor winding temperature.
- ✓PROFINET iO Terminal offline after 48+ hours runtime — EL iO modules suffer ARP table overflow in high-broadcast-noise factory networks (common in Indian sugar mills, paper plants). PHY chip memory exhaustion causes communication node timeouts.
- ✓FLEXBUS gateway unable to resolve PROFIBUS node addresses — Firmware corruption in EL gateway routing firmware after incomplete OTA update or extended power loss during flash cycle. Device descriptor tables become uninitialized.
- ✓Analog output linearity errors >2% across 4-20mA range — EL AO module DAC reference voltage shift due to thermal drift of precision resistor networks. Common after 3-5 years in high-ambient-temperature environments (Indian foundries, dye mills reaching 45°C+).

Frequently Asked Questions — EL Repairs
Do you repair EL equipment anywhere in India?+
Yes. Synchronics repairs the full EL product range across all states — AC drives, PLCs, servo amplifiers, I/O terminals, and fieldbus gateways. We offer PAN India express pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and 50+ other cities. All repairs are handled at our Vadodara, Gujarat facility by certified technicians. Typical turnaround is 5-7 working days.
Can Synchronics repair EL COMMANDER drives with burnt IGBT power stages?+
Yes, absolutely. EL COMMANDER IGBTs are prone to thermal runaway under overload or insufficient cooling. We perform gate-driver circuit analysis, replace IGBT modules with matched pairs (stress-tested to 150% rated current), and re-solder all high-current connections using lead-free solder per automotive-grade IPC-A-610 standard. We then perform no-load test and soft-start validation before dispatch.
How do you handle EL PLC firmware issues and data recovery?+
EL LOGIC controllers often suffer EEPROM corruption after brownouts or lightning surges common in Indian industrial areas. Synchronics uses specialized JTAG programmers to extract backup user program data (if accessible), restores OEM firmware from golden image repository, and performs flash chip replacement if necessary. We validate program memory integrity and backup battery function before return. Customers should maintain offline program backups on USB for emergencies.
What is the typical cost and lead time for EL drive repair in India?+
Repair costs vary: simple capacitor replacement (Rs 2,500-4,500), IGBT module swap (Rs 8,000-12,000), full control board rebuild (Rs 15,000-25,000). Express turnaround (48-72 hours) adds 15% surcharge. Standard lead time is 5-7 days. We provide free diagnostic report with quotes. For emergency production shutdown scenarios, Synchronics offers on-site troubleshooting support in Mumbai, Pune, and Ahmedabad regions.
Do you provide EL equipment calibration and certification after repair?+
Yes. All repaired EL equipment undergoes traceable calibration using ISO 17025-certified test equipment. Drive output voltage/frequency accuracy, analog module linearity (±0.5%), PLC real-time clock drift, and servo loop stability are verified against EL datasheet specifications. Calibration certificates with NABL accreditation are issued and valid for 12 months. We also provide functional proof tests under simulated load conditions matching customer process parameters.
How do I send my EL 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 EL 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 EL 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 EL 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.
