MR Equipment We Repair — By Category
MR Product Lines We Repair
Our engineers are trained on the full MR product range. Below are the major product families we service.
MR Servo Amplifiers
High-precision servo drive units for AC and DC servo motors. Common failures include capacitor degradation, IGBT module breakdown, encoder communication loss, and thermal management issues in humid Indian factory environments.
MR Motion Controllers & PLCs
Standalone and embedded motion control platforms for multi-axis positioning. Typical faults include SD card/flash memory corruption, Ethernet port failures, analog input/output signal loss, and communication protocol (PROFIBUS, CANopen) breakdowns.
MR Stepper Motor Drivers
Microstepping drivers for 2-phase and 3-phase stepper motors in textile machinery and packaging lines. Repair focus: power stage failures, step/direction signal conditioning issues, and thermal shutdown cycling from inadequate cooling.
MR Encoder & Position Feedback Modules
Incremental and absolute encoder interfaces with SSI, CANopen, and analog outputs. Common failures: connector oxidation, signal conditioner IC burnout, power supply regulation loss, and electromagnetic interference susceptibility in industrial environments.
MR Distributed I/O & Gateway Modules
Remote terminal units and fieldbus gateways (PROFINET, EtherCAT, Modbus TCP) for decentralized control architectures. Failures include ethernet port damage, isolation relay stiction, software corruption, and firmware update hangups.
MR Power Supply Units
Regulated DC and multi-output supplies for servo systems and controllers. Typical issues: capacitor leakage and swelling (especially in coastal and high-humidity Indian facilities), transformer coil opens, rectifier diode failures, and voltage regulation IC thermal stress.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common MR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MR equipment arriving at our workshop.
- ✓Servo amplifier power stage IGBT module failure — Thermal cycling stress, inadequate heatsinking in high-ambient-temperature Indian factories, or gate driver IC degradation. Often triggered by blocked cooling vents due to dust and moisture ingress.
- ✓Encoder signal loss or intermittent dropout — Connector pin corrosion from humidity and salt-laden air (critical in coastal Indian plants), shielding degradation, or onboard signal conditioner IC failure. Vibration-induced micro-disconnects also common in textile machinery.
- ✓Motion controller Ethernet port non-responsive or dropped connections — RJ45 connector solder joint cracks from thermal shock and mechanical stress, magnetics coil failure, or switching IC damage from ESD or lightning transients common in Indian monsoon seasons.
- ✓Stepper driver step/direction timing jitter or missed pulses — Input signal conditioning circuit degradation, microstepper current reference drift, or PWM switching noise from adjacent equipment. Poor PCB grounding and inadequate input filtering exacerbate the problem.
- ✓Power supply capacitor leakage and voltage regulation instability — High-temperature electrolytic capacitors (especially in sealed power modules) fail rapidly in Indian summer conditions exceeding 45°C. Voltage regulator IC thermal drift and solder joint fatigue are secondary contributors.
- ✓Software corruption or firmware upload failure causing controller lockup — Incomplete OTA updates interrupted by power loss, SD card wear-out from frequent program writes, EEPROM bit-flip from ESD, or corrupted bootloader image. Common after facility power instability or surges.

Frequently Asked Questions — MR Repairs
Do you repair MR servo drives and motion controllers throughout India?+
Yes. Synchronics has repaired MR servo amplifiers, stepper drivers, motion control boards, and encoder modules for automotive, textile, packaging, and pharmaceutical manufacturers across India for 30+ years. We offer PAN India door-pickup service from Mumbai, Delhi, Pune, Hyderabad, Chennai, Ahmedabad, Bangalore, Kolkata, and all other major cities. All repairs are performed in our ISO 9001 certified facility in Vadodara, Gujarat.
What is the typical turnaround time for MR servo drive repair?+
Standard MR servo amplifier and stepper driver repairs are completed within 5-7 business days after receipt and diagnostics. Urgent on-site or overnight repairs are available for premium customers in Gujarat and nearby states. Complex motion controller software recovery or custom encoder interface rebuilds may require 10-14 days. We provide daily status updates and expedite critical path items.
Can you repair older MR-J2 and MR-E3 series drives still running in my facility?+
Absolutely. Synchronics specializes in legacy MR servo systems. We maintain stock of hard-to-find discrete components for older MR-J2, MR-E3, and MR-E4 series drives, including gate drivers, isolation amplifiers, and thermal management components. Many Indian textile mills and precision shops still rely on these proven drives, and we keep them operational with genuine-quality replacements and thermal upgrade recommendations.
Do you offer warranty on MR drive and controller repairs?+
Yes. All Synchronics repairs include 12 months comprehensive warranty covering parts and labor against the same fault, provided installation environment and operating conditions remain within MR specifications. We also offer extended 24-month warranty options for mission-critical systems in automotive and pharmaceutical facilities. Warranty is void only for further damage from customer negligence, inadequate cooling, or electrical surges.
Can Synchronics help troubleshoot MR encoder communication or CANopen gateway problems?+
Yes. Our applications engineers troubleshoot encoder signal integrity, CANopen protocol issues, and PROFINET gateway configuration problems remotely or on-site. We use protocol analyzers and CAN/EtherCAT test tools to isolate signal conditioning failures, connector issues, or firmware mismatches. We can also reprogram MR gateway modules and test them against your live factory network topology before return shipment.
How do I send my MR 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 MR 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 MR 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 MR 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.
