EP Product Lines We Repair
Our engineers are trained on the full EP product range. Below are the major product families we service.
EP Stepper Drive Module (SDM)
Compact stepper motor controllers with integrated microstepping and pulse-direction interface. Common failures include encoder connection loss, microstepping waveform distortion, and thermal shutdown triggered by overload conditions in high-cycle textile and packaging machinery.
EP Servo Control Unit (SCU)
Real-time servo amplifiers with integrated motion controller supporting CANopen and EtherCAT protocols. Typical repair scope covers Hall effect sensor failures, IGBT bridge faults, resolver signal conditioning errors, and firmware corruption in pharmaceutical and food processing lines.
EP Embedded Controller (EC) Series
Industrial-grade embedded PLCs with modular I/O architecture and real-time Linux kernel support. Repair issues include NAND flash degradation, SD card corruption, Ethernet transceiver faults, and legacy firmware migration problems in multi-decade installations.
EP Industrial Networking Gateway (ING)
Protocol translation and fieldbus gateway modules for PROFIBUS, PROFINET, and Modbus-TCP integration. Common faults include transformer saturation in isolated power supplies, magnetic coupling degradation, optical isolation chip failure, and firmware version conflicts with legacy slave devices.
EP Precision Positioning Module (PPM)
Sub-micron accuracy motion control for high-speed automated assembly and precision metrology. Repair challenges include capacitive sensor contamination, analog signal path drift, reference voltage regulation failure, and mechanical hysteresis calibration loss after vibration exposure.
EP Power Management Controller (PMC)
Intelligent AC-DC and DC-DC converter control boards with integrated power factor correction and thermal management. Typical failures involve electrolytic capacitor drying, gate driver IC burnout under fault conditions, PFC inductor lamination separation, and control loop instability at temperature extremes.

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 EP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EP equipment arriving at our workshop.
- ✓EP SDM Encoder Lost Signal Error — Hall effect sensor magnetic interference or degraded shielding in high-frequency switching environments. Common in textile spinning frames and high-speed label printing systems where stepper synchronization is mission-critical.
- ✓EP SCU IGBT Bridge Partial Failure — Thermal cycling stress on solder joints between power die and baseplate, exacerbated by coolant contamination or inadequate heatsink thermal interface material. Typical in pharmaceutical liquid filling lines operating 22+ hours daily.
- ✓EP EC Series NAND Flash Wear Leveling Failure — Extended uptime in food processing facilities causes NAND flash bit error rate accumulation. Frequent parameter updates and logging operations accelerate wear in 8-10 year old installations running continuous 24/7 operations.
- ✓EP ING PROFINET Gateway Packet Loss Under Load — Transformer core saturation in isolated power supply or magnetic coupling bandwidth limitation when handling burst traffic from fast synchronous slave devices. Common during migration from legacy PROFIBUS to PROFINET Real-Time (IRT) in automotive supply shops.
- ✓EP PPM Capacitive Sensor Drift Post-Cleaning — Residual cleaning fluid or moisture absorption on sensor electrode surface causing parasitic capacitance shift. Precision metrology installations in bearing manufacturing and carbide tool grinding face repeated wash-down cycles.
- ✓EP PMC Power Factor Correction Inductor Lamination Separation — Mechanical vibration and thermal expansion mismatch between lamination stack and epoxy binder in industrial AC-DC converters feeding induction furnaces or arc welding equipment. Micro-fractures propagate over 3-5 years of continuous duty.

Frequently Asked Questions — EP Repairs
Do you repair EP equipment anywhere in India?+
Yes. Synchronics repairs the complete EP product range across all Indian cities — stepper drives, servo controllers, embedded PLCs, industrial gateways, and precision motion systems. We offer door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Kolkata, and all tier-2 industrial clusters. All repairs handled in our Vadodara, Gujarat facility with 5-7 day typical turnaround.
What is the typical repair cost for an EP SCU servo drive?+
EP SCU repair costs depend on fault severity. IGBT power stage replacement typically runs 15,000-35,000 INR. Control circuit board repair (Hall sensors, signal conditioning) ranges 8,000-18,000 INR. Firmware reprogramming or flash upgrade adds 3,000-5,000 INR. Synchronics provides detailed quotation after diagnostic testing — no hidden charges.
Can Synchronics upgrade my older EP SDM stepper drives to support CANopen networking?+
Yes. Synchronics can retrofit EP SDM-2.8A and SDM-5.6A units with CANopen firmware upgrade and CAN transceiver module installation. This is cost-effective for textile and packaging customers wanting to network legacy stepper axes into modern SCADA systems without motor replacement. We provide mechanical adapter brackets and connector harness kits matched to your machine control cabinet layout.
How do you handle obsolete EP components that are no longer manufactured?+
Synchronics maintains a network of industrial electronics component sourcing partners across Europe and India. For discontinued EP parts, we identify functional equivalents from secondary market suppliers or perform board-level redesign using modern industrial-grade components. We validate cross-parts with full electrical and thermal testing before installation. Customers receive documentation of substituted parts with performance warranties.
Do you offer calibration certificates for EP precision positioning modules?+
Yes. All EP PPM (Precision Positioning Module) repairs include factory-grade calibration against traceable reference standards. Synchronics issues NABL-compliant calibration certificates documenting zero-point accuracy, linearity error, and hysteresis performance at 20-25 degrees Celsius. Certificates valid for 12 months and meet ISO 9001:2015 and pharmaceutical GMP documentation requirements.
How do I send my EP 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 EP 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 EP 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 EP 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.
