SIASUN Equipment We Repair — By Category
SIASUN Product Lines We Repair
Our engineers are trained on the full SIASUN product range. Below are the major product families we service.
SIASUN Robot Arm Series (CR, CRB, SR, NX)
Six-axis collaborative and industrial robotic arms for welding, material handling, and assembly. Common issues include servo encoder faults, joint bearing wear, electrical connector corrosion, and firmware corruption in the motion control unit.
SIASUN AGV (Automated Guided Vehicle) Control System
Navigation and fleet management electronics for autonomous material transport in warehouses and manufacturing plants. Typical faults involve gyroscope drift, LiDAR module failure, wireless communication dropout, and power distribution PCB degradation.
SIASUN Robot Controller and Teach Pendant
Core control units and operator interface hardware for robot programming and real-time motion supervision. Repair scope covers touchscreen degradation, memory corruption, CAN-bus communication errors, and power supply regulation failures.
SIASUN Servo Drive and Motion Control Module
Servo amplifiers and stepper drive modules powering joint motors and linear actuators in SIASUN systems. Common failures include MOSFET burnout, encoder signal loss, thermal sensor malfunction, and control signal interpretation errors.
Why Choose Synchronics for SIASUN Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on SIASUN equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 SIASUN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SIASUN equipment arriving at our workshop.
- ✓Robot arm joint encoder signal loss — SIASUN encoder connectors suffer vibration-induced pin separation in high-cycle production environments. Condensation and coolant spray accelerate connector corrosion, breaking the incremental pulse signal to the motion controller.
- ✓Servo drive MOSFET or capacitor thermal runaway — SIASUN servo drives in continuous-duty welding or stamping applications experience sustained current spikes that overheat power transistors. Inadequate heatsink mounting or blocked cooling vents force early component failure.
- ✓Teach pendant touchscreen unresponsive or ghost touches — SIASUN teach pendants used on noisy factory floors accumulate dust and humidity inside the LCD assembly. Capacitive touch sensor degradation and moisture-induced short circuits disable operator interface responsiveness.
- ✓AGV navigation drift - robot moves off intended path — SIASUN AGV gyroscope and compass modules drift under strong electromagnetic fields from nearby welding stations or high-power motor drives. Firmware calibration files may also become corrupted during power cycle interruptions.
- ✓Robot controller CAN-bus communication error or fault code 0x0201 — CAN termination resistors in SIASUN backbone network cables deteriorate or become disconnected during maintenance or equipment relocation. Controller firmware version mismatch between main unit and servo drives also triggers protocol errors.
- ✓Power supply unit voltage ripple or dropout under load — SIASUN power supply electrolytic capacitors age and lose capacitance, or aging transformer insulation develops partial short circuits. Overheating caused by dust accumulation on heatsinks accelerates degradation.

Frequently Asked Questions — SIASUN Repairs
Do you repair SIASUN equipment anywhere in India?+
Yes. Synchronics repairs the full SIASUN product range — robot arms, AGV systems, servo drives, controllers, and teach pendants. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other industrial hubs. All equipment is serviced at our ISO 9001-certified facility in Vadodara, Gujarat, with 24-48 hour turnaround for critical repairs.
What is the typical repair time for a SIASUN robot arm servo encoder fault?+
Encoder connector replacement and recalibration typically takes 4-6 hours at Synchronics if the servo drive itself is functional. If the encoder signal path includes drive-side circuit board damage, add 8-12 hours for component-level repair and joint testing. We prioritize robot arm repairs because downtime directly impacts production schedules for automotive and assembly-line manufacturers.
Can Synchronics reprogram SIASUN teach pendants after repairs?+
Yes. Synchronics has factory-level programming tools for SIASUN teach pendants and main controllers. After hardware repair, we reload original firmware, restore calibration parameters, and verify touchscreen responsiveness and pendant-to-arm communication. We do not modify customer production code, but we ensure the hardware interface layer is fully functional.
Why does my SIASUN AGV keep drifting during autonomous navigation?+
AGV navigation drift is usually caused by gyroscope/compass calibration loss under electromagnetic interference (EMI) from welding areas or unshielded motor drives. SIASUN AGVs are sensitive to magnetic field changes. Synchronics recalibrates gyro and compass modules, checks LiDAR module alignment, and tests navigation in your facility environment if needed. Improper floor surface reflectivity can also contribute — we advise on optimal operating conditions.
Do you stock SIASUN spare parts or do I need to source them separately?+
Synchronics maintains inventory of critical SIASUN spares — encoders, servo MOSFETs, capacitor kits, connector assemblies, and thermal sensors. For specialized SIASUN robot arm gearbox assemblies or complete servo drive modules, we source directly from authorized distributors with 5-7 day lead times. We can also order your parts on your behalf and integrate them at repair.
How do I send my SIASUN 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 SIASUN 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 SIASUN 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 SIASUN 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.
