KND Equipment We Repair — By Category
KND Product Lines We Repair
Our engineers are trained on the full KND product range. Below are the major product families we service.
KND HSV Series Servo Drives
Compact servo amplifiers (HSV-04, HSV-06, HSV-08, HSV-12) for stepper and servo motors up to 2.5 kW. Common faults include thermal shutdowns from inadequate cooling, encoder communication loss, and power supply rail failures causing torque ripple.
KND MMS Motion Management System
Multi-axis motion controller with Ethernet and CANopen connectivity for coordinated servo motion. Frequent issues include firmware corruption, communication timeout errors, and axis synchronization drift requiring calibration.
KND ASD Servo Motor Series
BLDC servo motors (100W to 2.5 kW) with integrated encoders for direct coupling to KND drives. Repair concerns center on encoder bearing wear, phase winding short-circuits, and connector pin corrosion in humid Indian textile mill environments.
KND PLC and I/O Modules
Programmable logic controllers and distributed I/O for machine automation integration with KND servo systems. Common faults include SD card read errors, input/output module relay failures, and real-time clock battery depletion.
KND Encoder Feedback Systems
Incremental and absolute rotary encoders supplying position feedback to KND servo drives. Typical failures involve connector oxidation, bearing friction increase, and signal cable shielding degradation causing intermittent position errors.
KND Power Supply Modules
24 VDC regulated power supplies (30W to 480W) with short-circuit protection for KND control electronics. Repair issues include capacitor aging, output voltage drift, and thermal fuse nuisance trips under transient load conditions.

Common KND Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KND equipment arriving at our workshop.
- ✓KND servo drive thermal shutdown and no restart — HSV series drives overheat due to inadequate heatsink ventilation in enclosed cabinet installations common across Indian textile machinery. Thermal sensor calibration drift also triggers false shutdown signals.
- ✓Encoder communication loss - SER.ERR fault code — KND drives lose encoder signal due to connector pin corrosion, damaged shielded cable routing near power lines, or encoder bearing play causing intermittent contact. Moisture ingress in humid Indian manufacturing plants accelerates connector degradation.
- ✓Axis synchronization drift in KND MMS multi-axis systems — Firmware version mismatch between motion controller and individual HSV drives, or accumulated position error from servo loop tuning parameters incompatible with load inertia. Common in Indian packaging lines where belt-drive coupling introduces variable friction.
- ✓KND drive output power loss during full-load operation — Internal MOSFET gate driver failure or phase winding short in power stage due to repeated thermal cycling. KND drives in Indian foundries and die-casting plants experience extreme temperature variations between ambient and operating conditions.
- ✓KPC PLC SD card read errors and program loss — SD card file system corruption from improper shutdown during firmware updates or power loss events. Insufficient UPS backup in Indian SME manufacturing facilities results in abrupt power cuts.
- ✓KND power supply output voltage drift and intermittent load faults — Aging aluminum electrolytic capacitors in KPS series modules fail at rated life (3000-5000 hours) accelerated by Indian ambient temperatures averaging 35-40°C. Voltage regulation feedback network resistor tolerance drift also contributes.

Frequently Asked Questions — KND Repairs
Do you repair KND equipment anywhere in India?+
Yes. Synchronics repairs the complete KND servo drive, motion controller, and automation product range across all of India. We provide PAN India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other cities — equipment shipped to our state-of-the-art repair facility in Vadodara, Gujarat. Standard repair turnaround is 5-7 working days with full workshop warranty.
What is the typical repair cost for KND HSV servo drive faults?+
HSV series repair costs range from Rs 8,000 to Rs 22,000 depending on fault complexity. Simple connector replacement or thermal sensor recalibration runs Rs 8,000-12,000. MOSFET replacement or power stage rebuild ranges Rs 15,000-22,000. We provide free diagnostic assessment before repair, and repair cost estimates typically 60% less than new drive replacement. Synchronics offers fixed-price repair packages for common KND faults.
How do I identify which KND product I have and what faults to expect?+
KND model identification is found on the silver label affixed to the device. Servo drives show HSV-XX format (X=axis number and power rating). Motion controllers display KPC-XXX model codes. Send us a photograph of the device label and describe observed error codes or symptoms — our technical team will email you fault diagnosis and repair estimate within 2 hours. Contact synchronics.co.in with model number and fault symptoms for instant support.
Does Synchronics stock genuine KND spare parts?+
Yes. We maintain authorized inventory of KND servo drive power modules, encoder connectors, thermal sensors, and servo motor rotor assemblies sourced directly from KND distributors. We also supply second-source industrial-grade components (capacitors, MOSFETs, optoelectronics) rated equivalent to KND original specs. All spare parts carry warranty. Lead time for special order components is 7-10 days ex-Korea.
Can you reprogram or recalibrate KND controllers after repair?+
Absolutely. Synchronics has licensed KND software tools (MMS IDE, PLC development environment) and performs post-repair reprogramming, axis calibration, encoder offset adjustment, and servo loop tuning specific to your application. We backup your original program code before any work and validate all control logic after repair. Custom motion profile development for Indian machinery applications is available as a service.
How do I send my KND 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 KND 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 KND 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 KND 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.
