ELTRA Equipment We Repair — By Category
ELTRA Product Lines We Repair
Our engineers are trained on the full ELTRA product range. Below are the major product families we service.
Incremental Encoders (ELX, EL, ER Series)
Compact optical and magnetic incremental encoders for speed feedback and position counting. Common failures include LED degradation, phototransistor contamination in dusty environments, and connector corrosion from humidity and coolant spray.
Absolute Encoders (EAM, EAS, EAR Series)
Multi-turn and single-turn absolute encoders with SSI, CANopen, and Profibus outputs for closed-loop motion systems. Typical faults involve grey code conversion errors, battery backup failure in multi-turn units, and CRC checksum mismatches on digital output.
Rotary Encoder Modules (Customized Variants)
Bearing-integrated and hollow-bore encoder units designed for servo motors, spindles, and robotic joints. Repair challenges include shaft runout drift, bearing preload loss, and signal noise from electromagnetic interference in packed industrial cabinets.
Linear Position Transducers (EL Series)
LVDT and magnetostrictive linear transducers for stroke measurement on hydraulic cylinders, pneumatic actuators, and material handling conveyors. Common issues: cable break near flex zone, potentiometric slider contamination, and measurement drift from thermal expansion.
Profibus and Industrial Protocol Adapters
Gateway modules converting ELTRA encoder signals to Profibus DP, EtherCAT, and MODBUS RTU for PLC integration. Faults include firmware corruption, baud rate mismatch, and node address conflicts on shared industrial networks.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ELTRA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELTRA equipment arriving at our workshop.
- ✓ELTRA encoder LED output degradation or loss — Phototransistor or LED element failure due to age, thermal cycling, or contamination from coolant mist and metal dust in machine tool and spindle environments. Optical path blockage from machine swarf accumulation also reduces signal amplitude below PLC threshold.
- ✓Absolute encoder CRC or checksum error on digital output — Firmware corruption in multi-turn ELTRA absolute encoders after power surge or improper shutdown. Memory bit flip can also occur due to electromagnetic interference (EMI) from adjacent servo drives or welding equipment in Indian manufacturing plants.
- ✓ELTRA encoder connector intermittent signal dropout — M23, DIN 41612, or M12 connector corrosion caused by humidity, coolant splash, or inadequate IP rating for washdown environments. Backplate connector contacts oxidize and lose continuity under vibration or thermal cycling.
- ✓ELTRA SSI or CANopen protocol frame errors — Baud rate or timing mismatch between encoder output and PLC input module. Multi-turn battery backup depletion can cause grey code decode failure or node ID collision on shared industrial CANbus networks in textile mills and process plants.
- ✓ELTRA linear transducer output drift or nonlinearity — Potentiometric slider or LVDT core displacement due to mechanical shock, hydraulic pressure surge, or inadequate damping on heavy machinery. Thermal expansion mismatch between transducer housing and cylinder body also causes calibration shift.
- ✓ELTRA encoder bearing preload loss and shaft runout — Extended service in high-speed spindle or servo motor applications causes bearing race degradation and axial play growth. Radial runout exceeds encoder optical/magnetic detection tolerance, resulting in speed ripple and position jitter in closed-loop feedback.

Frequently Asked Questions — ELTRA Repairs
Do you repair ELTRA equipment anywhere in India?+
Yes. Synchronics repairs the full ELTRA encoder and transducer range — incremental, absolute, SSI, CANopen, Profibus, and linear position sensors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Jaipur, and all other major cities. All repairs are performed at our main facility in Vadodara, Gujarat, with same-day triage and 5-7 day turnaround for most failures.
What is the typical repair cost and turnaround for ELTRA ELX63 and EAM63 encoders?+
For standard ELTRA incremental encoders (ELX63, EL series), repair cost ranges from INR 8,000-18,000 depending on fault severity. Absolute encoders (EAM63, EAR series) typically cost INR 12,000-25,000 if battery backup or firmware is involved. Most repairs complete in 5-7 working days. Express diagnostics (24-48 hours) available for critical production lines. We provide detailed failure reports and recommend preventive maintenance intervals.
Do you stock genuine ELTRA spare parts and modules?+
Yes. Synchronics maintains inventory of common ELTRA encoder cartridges, optical elements, connectors, mounting brackets, and protocol gateway modules. We import genuine ELTRA components directly from Italy to ensure original specification and warranty compliance. Custom encoder builds (non-standard flange, cable length, output protocol) are coordinated through ELTRA distributors within 3-4 weeks.
Can you repair ELTRA encoders if they are integrated into my servo motor or spindle head?+
Yes. Our technicians carefully extract integrated ELTRA encoders from servo motors (ABB, Siemens, Yaskawa), spindle heads, and robotic joint assemblies. Encoders are repaired separately, then reinstalled with proper alignment and torque specifications. We also perform parallel repairs on the host motor or drive during the same service window to maximize your uptime.
What warranty do you provide on ELTRA encoder repairs?+
All Synchronics ELTRA repairs include 12 months warranty against the same fault. If an encoder fails within 12 months due to the original defect, we repair or replace it free of labor and service charge. Extended 24-month warranties are available for mission-critical textile mill encoders, bottling line transducers, and automotive spindle feedback systems at a small premium. Terms and conditions apply.
How do I send my ELTRA 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 ELTRA 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 ELTRA 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 ELTRA 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.
