INFRANOR Equipment We Repair — By Category
INFRANOR Product Lines We Repair
Our engineers are trained on the full INFRANOR product range. Below are the major product families we service.
INFRANOR Stepper Drives
Single and multi-axis stepper motor drivers designed for precise positioning and synchronisation in textile looms, packaging machinery, and CNC equipment. Common faults include phase winding faults, microstepping resolution errors, and communication loss with host controllers.
INFRANOR Servo Amplifiers
Closed-loop servo drives for AC brushless and brushed servo motors. Widely used in Indian textile machinery, injection moulding presses, and precision assembly automation. Prone to encoder feedback loss, gain tuning drift, and capacitor degradation.
INFRANOR Positioning Controllers
Dedicated motion control cards and modules for multi-axis synchronisation in automatic weaving, converting, and material handling systems. Repair focus: EEPROM corruption, communication protocol errors, and real-time timing drift.
INFRANOR Stepper Motor Modules
Compact step/direction stepper control modules integrated into OEM equipment. Common failures: internal MOSFET burnout, microstepping logic faults, and coil insulation breakdown under thermal stress.
INFRANOR Communication Interfaces
RS485, CANbus, and proprietary fieldbus gateway modules for integrating INFRANOR drives into distributed control architectures. Failures include transceiver IC damage, protocol stack corruption, and isolation layer breakdown.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common INFRANOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INFRANOR equipment arriving at our workshop.
- ✓Stepper Phase Winding Open Circuit — Extended thermal cycling combined with vibration causes copper winding insulation to crack, typically at phase coil termination points. INFRANOR stepper drives in hot environments (textile dyeing, extruders) see accelerated failure after 5-8 years.
- ✓Encoder Communication Loss with CA6 Servo — Shielded encoder cables in high-EMI environments (proximity to VFDs, welders) pick up noise, corrupting the feedback signal. INFRANOR CA6 servo amplifiers become unstable and trigger encoder timeout faults, causing servo motor oscillation.
- ✓SMCI36 Microstepping Resolution Degradation — Internal PWM timing circuits drift due to capacitor ageing and temperature excursions. INFRANOR SMCI36 controllers lose micro-step accuracy, causing vibration and positional errors in textile looms and embroidery machinery.
- ✓IPC-3000 EEPROM Parameter Corruption — Power supply transients, watchdog resets, or firmware upload interruptions corrupt parameter blocks stored in non-volatile memory. Symptoms include loss of acceleration profiles, axis offset tables, and synchronisation data in multi-axis systems.
- ✓Servo Amplifier Capacitor Bank Bulging — INFRANOR CA4 and CA6 amplifiers use aluminum electrolytic capacitors that degrade in high-temperature, high-ripple current environments common in Indian injection moulding shops and die-casting lines. Bulging indicates imminent failure.
- ✓COMM-485 Isolation Layer Breakdown — Repeated ESD events and transient voltage spikes on RS485 fieldbus lines degrade optoisolator LED and photodiode junctions. Signal integrity deteriorates gradually, causing intermittent data corruption and system hangs in networked INFRANOR installations.

Frequently Asked Questions — INFRANOR Repairs
Do you repair INFRANOR equipment anywhere in India?+
Yes. Synchronics repairs the full INFRANOR product range — stepper drives, servo amplifiers, positioning controllers, and communication modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other major cities. All repairs handled at our main facility in Vadodara, Gujarat. Typical turnaround: 5-7 working days for standard faults; critical emergency repairs arranged on request.
How do you diagnose INFRANOR stepper drive faults accurately?+
Synchronics uses specialised test benches with precision stepper motors, oscilloscopes, and INFRANOR-compatible test loads to validate each axis independently. We perform phase continuity testing, microstepping resolution verification, and load torque profiling. EEPROM parameters are extracted and analysed for corruption. This methodical approach ensures faults are root-caused before repair, eliminating comebacks and field failures after return.
What is the typical repair cost for an INFRANOR CA6 servo amplifier?+
CA6 servo amplifier repairs typically range from INR 8,000 to 18,000 depending on fault severity — capacitor replacement costs less; power stage MOSFET failure or encoder circuit repair costs more. Synchronics provides free diagnostic reports with cost estimates before proceeding. We also offer refurbished CA6 units as cost-effective alternatives for critical standby spares. Request a quote with your unit's serial number and symptom description.
Can you repair INFRANOR drives that are still in use on active production lines?+
Yes. Synchronics maintains in-stock refurbished INFRANOR stepper drives, servo amplifiers, and positioning modules to provide drop-in replacements while your original unit is being repaired. This zero-downtime service is critical for Indian textile mills, packaging converters, and automotive suppliers running continuous shift operations. We also offer expedited repair-within-48-hours service for emergency failures at a small premium.
Do you stock INFRANOR spare parts and refurbished units?+
Synchronics holds inventory of refurbished INFRANOR SMCI stepper drives, CA-series servo amplifiers, and communication modules ready for immediate deployment. We also source OEM spare parts including capacitor banks, encoder cables, and firmware update discs. Contact our spare parts team in Vadodara for availability and lead times. For obsolete INFRANOR models, we offer functional equivalents from compatible manufacturers with full integration support.
How do I send my INFRANOR 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 INFRANOR 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 INFRANOR 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 INFRANOR 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.
