EISTAR Product Lines We Repair
Our engineers are trained on the full EISTAR product range. Below are the major product families we service.
ES Series Servo Drives
EISTAR ES-series compact AC servo drives (5W to 50W) used in precision packaging equipment and small-format textile looms. Common faults include encoder communication loss, capacitor ripple, and thermal shutdown triggered by inadequate heatsinking in humid Indian factory environments.
ECS Motion Controllers
Multi-axis motion control systems with integrated step/direction and analog input interfaces. Widely used in Indian food-processing machinery and print-finishing equipment. Repairs focus on firmware corruption, CAN-bus isolation, and PWM output stage failures.
EPOS Positioning Electronics
Standalone position controllers with Modbus RTU/TCP for synchronized multi-motor applications. Common in Indian cotton ginning mills and sugar plant conveyor automation. Typical faults: memory EEPROM degradation, relay contact corrosion, and Modbus communication timeouts under electrical noise.
ES PowerModule Expansion Cards
High-current extension modules for ES-series drives supporting single-phase to three-phase conversion and regenerative braking. Repairs include IGBT replacement, snubber diode testing, and gate-driver IC re-soldering for thermal cycling failure.
EiCAP Distributed IO Nodes
CANopen-enabled remote IO modules for decentralized control in large Indian textile and food factories. Faults: CANopen node ID conflicts, power-supply regulation failure, and relay coil burnout from inductive load switching.

Common EISTAR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EISTAR equipment arriving at our workshop.
- ✓Servo encoder communication loss or dropout — EISTAR ES-series drives use 5V TTL encoder interfaces susceptible to noise coupling in Indian mills with poor cable shielding and frequent electrical transients. Encoder connectors corrode in humid environments, and firmware version mismatches cause protocol errors.
- ✓Thermal shutdown and repeated de-rate on load — EISTAR ES drives mounted in compact panels without adequate ventilation—common in Indian cottage-sector packaging units. Heatsink paste degradation, fan blockage from textile lint, and missing thermal vias under power transistors cause junction temperature rise above 85C setpoint.
- ✓CANopen or Modbus timeout and node dropout — EISTAR motion controllers and EPOS devices lose communication when Indian industrial networks have intermittent EMI bursts from welding equipment, motor starters, or VFDs in shared electrical panels. Incorrect termination resistors (120 ohm) and improper shielding exacerbate the issue.
- ✓Capacitor ripple voltage above 20% nominal DC bus — EISTAR ES-series drives use compact electrolytic capacitor banks rated for 85C; in Indian factories running 24/7 without proper thermal management, caps age rapidly and ESR increases. Aged capacitors cause slow startup, noise in analog outputs, and sporadic fault codes E01 or E03.
- ✓EEPROM or firmware corruption after power loss — EISTAR ECS controllers store config in on-board EEPROM without battery-backed real-time clock. Indian power grids with frequent brownouts (especially rural areas and cotton belts) cause mid-write interruption, corrupting parameter tables and forcing factory reset.
- ✓IGBT or power-stage short circuit under load pulse — EISTAR ES PowerModule IGBT gates driven by older-generation gate-driver ICs (IR2110) sensitive to timing skew under fast transients. Indian machinery running rapid acceleration/deceleration cycles (like printing press feeders) trigger cross-conduction and IGBT latchup.

Frequently Asked Questions — EISTAR Repairs
Do you repair EISTAR equipment anywhere in India?+
Yes. Synchronics repairs the full EISTAR product range—servo drives, motion controllers, positioning electronics, and distributed IO modules. We offer PAN-India door pickup and drop service from major cities including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and Vadodara. All repairs are completed in our main facility in Vadodara, Gujarat, with 5-7 business day turnaround for most EISTAR servo drive faults.
Can you repair EISTAR ES-series drives that are no longer under warranty?+
Absolutely. EISTAR ES-series servo drives (ES-5A through ES-100A) are our core repair focus. We repair out-of-warranty units for Indian textile mills, packaging companies, and food processors. Component-level repair means we replace failed transistors, capacitors, and ICs rather than swapping entire boards. Repairs are 40-60% cheaper than replacement and include a 1-year parts warranty.
What does encoder interface repair involve for EISTAR drives?+
EISTAR ES-series encoder interfaces are 5V TTL; we test the interface circuit (gates, buffers, and input-protection resistors), re-solder corroded encoder connectors, replace damaged interface ICs, and re-flash firmware with the latest EISTAR bootloader. We also provide shielded encoder cables and termination resistors as part of the repair package. After repair, we simulate encoder signals and verify communication at 1000 rpm to ensure stable operation in your mill environment.
How do you handle EISTAR firmware or parameter corruption?+
Synchronics has EISTAR ES, ECS, and EPOS firmware extraction and re-programming capability. If your drive has corrupted parameters after a power loss or failed firmware update, we read the EEPROM, restore factory defaults or your backup file, and re-program via ICSP or USB bootloader. If you have a config backup file, we can restore your exact motor settings and network addresses. For parameter-only recovery, turnaround is 2-3 days.
Do you offer preventive maintenance for EISTAR motion control systems in Indian factories?+
Yes. Synchronics provides on-site preventive maintenance for EISTAR ES, ECS, and EPOS installations in Gujarat, Maharashtra, and Rajasthan. We perform thermal imaging, capacitor ESR testing, CAN-bus signal analysis, and firmware health checks. Indian mills running 24/7 benefit from annual PM contracts; we typically identify 2-3 early-stage faults per visit and prevent unplanned downtime. Contact us for a site assessment and preventive maintenance quote.
How do I send my EISTAR 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 EISTAR 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 EISTAR 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 EISTAR 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.
