JAKI Equipment We Repair — By Category
JAKI Product Lines We Repair
Our engineers are trained on the full JAKI product range. Below are the major product families we service.
JAKI Brushless Servo Drives
High-torque brushless motor control systems for packaging and textile machinery. Common faults include Hall sensor misalignment, phase loss detection errors, and thermal runaway in continuous operation.
JAKI Stepper Motor Controllers
Microstepping drivers for precision positioning in CNC and labeling equipment. Typical repairs involve burned output FETs, step/direction signal loss, and logic board firmware reflashing.
JAKI PLC-Motion Modules
Integrated motion control cards for JAKI PLC platforms. Repair scope includes analog output drift, encoder feedback loss, and communication protocol errors between main CPU and motion card.
JAKI Spindle Drive Systems
AC spindle control for precision drilling and milling applications. Common issues are speed feedback errors, soft-start capacitor failure, and regenerative braking circuit faults.
JAKI Encoder Interface Cards
Signal conditioning and counting modules for incremental and absolute encoders. Failures typically stem from ESD damage, optocoupler burnout, and frequency instability at high RPM.

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 JAKI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in JAKI equipment arriving at our workshop.
- ✓Hall sensor signal loss or phase error — JAKI brushless servo drives rely on three Hall sensors for commutation. Contamination, corrosion, or mechanical misalignment of the sensor disc in high-vibration environments (textile mills, packaging lines) causes intermittent phase dropout and loss-of-sync faults.
- ✓Overcurrent trip during startup or load surge — JAKI stepper and servo drives limit current via shunt resistors and analog comparators. Thermal drift, shunt resistance drift, or software current-limit setting misalignment causes nuisance trips. Common in Indian plants with unstable power supply or sudden mechanical jam scenarios.
- ✓Encoder feedback missing or noisy — JAKI encoder interface cards use optocoupler front-ends and high-speed counters. Cable damage, connector corrosion, or ESD stress on the input stage degrades signal integrity, especially in humid Indian factory environments. Results in speed control loops going unstable.
- ✓Thermal shutdown or heatsink temperature runaway — JAKI drives in continuous duty mode (24/7 running) experience aging of power semiconductors and thermal interface material degradation. Heatsink fans clog with textile dust or packaging foam debris, reducing cooling efficiency and forcing thermal cutoff.
- ✓Firmware corruption or program memory error — Power supply spikes, electrostatic discharge, or improper shutdown can corrupt JAKI drive firmware during critical operations. Indian power quality issues and monsoon-related surges are common culprits. Drive enters safe state or becomes unresponsive.
- ✓Soft-start capacitor failure in spindle drives — JAKI spindle AC drive soft-start circuits use large electrolytic capacitors to limit inrush current. Repeated thermal cycling in Indian summers (40-45°C ambient) accelerates capacitor aging, leading to swelling, leakage, or open-circuit failure.

Frequently Asked Questions — JAKI Repairs
Do you repair JAKI equipment anywhere in India?+
Yes. Synchronics is an authorized JAKI repair center with expertise across all JAKI servo drives, stepper controllers, and PLC motion modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all major industrial cities. All repairs are handled in our ISO-certified facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days including bench testing.
What is the typical repair cost for a JAKI servo drive?+
JAKI servo drive repair costs range from Rs. 8,000 to Rs. 25,000 depending on fault severity and component replacement needs. Hall sensor replacement runs Rs. 5,000-8,000. Power FET and driver IC replacement is Rs. 10,000-15,000. We provide a free diagnostic report and cost estimate before undertaking repairs. Emergency turnaround (24-48 hours) is available at a premium.
Can Synchronics repair JAKI stepper drives without a schematic?+
Absolutely. Our reverse-engineering team has rebuilt JAKI stepper controllers across all SM-series models without original schematics. We use functional block diagrams, component-level testing, and comparison with known good units to isolate faults. Most common repairs — output FET replacement, PWM circuit diagnostics, and step/direction input conditioning — are handled on first-sight diagnosis.
Do you offer warranty on JAKI drive repairs?+
Yes. All JAKI drive repairs include a 12-month comprehensive warranty covering parts and labor. We also offer extended 24-month warranty for critical production equipment at 15% of repair cost. If a repaired unit fails within warranty due to our workmanship, we repair it free of charge and cover courier costs both ways.
How do I know if my JAKI encoder card needs repair or replacement?+
Common signs of encoder card failure include erratic speed readouts, loss of position feedback, or red LED fault indicators on the card. Synchronics tests your encoder signals using precision digital oscilloscopes and logic analyzers. If the card can be salvaged (optocoupler or connector repair), repair cost is typically 40-50% of replacement. If internal IC damage is detected, we recommend replacement with genuine JAKI spare or compatible industrial equivalent.
How do I send my JAKI 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 JAKI 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 JAKI 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 JAKI 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.
