Common A-KYUNG CORP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in A-KYUNG CORP equipment arriving at our workshop.
- ✓A-KYUNG servo drive commutation phase loss — A-KYUNG BLDC controllers sense rotor position via Hall sensors or back-EMF estimation. Phase commutation failure occurs when Hall wiring develops intermittent contact or firmware Hall-to-PWM timing logic becomes corrupted after power surges, causing erratic motor torque and grinding noise.
- ✓A-KYUNG stepper driver coil open-circuit fault — A-KYUNG stepper drivers energise phase windings via MOSFET H-bridges. Thermal fatigue, solder joint cracking, and manufacturing stress cause phase coil or winding open-circuits, detected as zero current draw and loss of holding torque. Common in legacy AK-STEP-2PH-48V units under continuous 100°C ambient operation.
- ✓A-KYUNG motion controller encoder signal noise immunity — A-KYUNG MCM series reads incremental encoder signals in high-EMI factory environments. Long encoder cables unshielded or routed alongside VFD cables induce noise, causing phantom step pulses and position tracking errors. Firmware threshold sensitivity often requires tuning for site-specific EMI levels.
- ✓A-KYUNG servo amplifier output current limiting nuisance trips — A-KYUNG AS-200W through AS-2000W amplifiers include dynamic current limiting to protect motors during stall or overload. Aging sense resistors, ADC calibration drift, and load inertia mismatch cause premature current limit activation during normal ramp profiles, blocking machine cycles.
- ✓A-KYUNG PLC program memory bit corruption — A-KYUNG PLC modules store user programs in ferroelectric or flash EEPROM. Repeated power-off transients, voltage spikes during capacitor discharge, and accumulated cosmic ray bit flips corrupt ladder logic. Users observe random I/O state changes and program execution hangs.
- ✓A-KYUNG power supply output voltage regulation drift — A-KYUNG PSU modules use TL431 shunt regulators and optocoupler feedback. Aging output filter capacitors, thermal coefficient drift in feedback resistors, and optocoupler LED degradation cause DC output to drift from 24V nominal to 26-27V or 21-22V, affecting downstream servo and stepper circuits.

Frequently Asked Questions — A-KYUNG CORP Repairs
Do you repair A-KYUNG CORP equipment anywhere in India?+
Yes. Synchronics repairs the full A-KYUNG CORP product range - servo drives, stepper controllers, motion modules, and power supplies across all Indian manufacturing hubs. We offer same-day PAN India pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and 50+ smaller cities. All repairs are completed at our ISO 9001 facility in Vadodara, Gujarat with 10-15 day turnaround.
What is the typical cost and turnaround time for A-KYUNG servo drive repair?+
A-KYUNG BLDC and AC servo drive repair typically costs INR 4,000-12,000 depending on fault severity (capacitor replacement vs. full firmware reprogram). Turnaround is 7-10 working days including diagnostics, component replacement, and thermal validation. We provide one-year limited warranty on all servo amplifier repairs. Emergency express repair (3-5 days) is available for critical production lines at 25% surcharge.
Can Synchronics handle A-KYUNG stepper driver firmware corruption?+
Yes. A-KYUNG stepper drivers often experience firmware corruption after power transients or improper shutdown. Synchronics has factory firmware images and parameter sets for all AK-STEP series models. We extract corrupted firmware, validate checksums, reflash using serial bootloader, and test micro-stepping resolution before return. No data loss occurs because user configuration is stored separately from firmware code.
Does Synchronics repair A-KYUNG motion control modules used in textile looms?+
Absolutely. Many Indian textile mills use A-KYUNG MCM-4AXIS controllers for dobby looms and Jacquard mechanisms. Common issues we repair include encoder signal dropout, EEPROM parameter loss, and encoder cable intermittency under high EMI. We have factory technical data and repair jigs for A-KYUNG motion processors. Textile mills often send units during maintenance shutdowns for preventive board testing.
What warranty and testing does Synchronics provide on A-KYUNG CORP repairs?+
All A-KYUNG CORP repairs include 1-year limited warranty against same fault recurrence. Before shipment, we perform full functional load testing - servo drives are tested with actual motor loads, stepper controllers are run through multi-axis interpolation cycles, and PLC modules execute user programs. We provide detailed repair certificates with before/after oscilloscope waveforms and parameter verification sheets.
How do I send my A-KYUNG CORP 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 A-KYUNG CORP 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 A-KYUNG CORP 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 A-KYUNG CORP 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.
