AUTORK Product Lines We Repair
Our engineers are trained on the full AUTORK product range. Below are the major product families we service.
AK-series Servo Drives
Compact servo amplifiers for multi-axis CNC machines and robotic arms. Common faults include encoder signal loss, thermal shutdown during high-speed cycles, and PWM output failures causing servo hunting or position drift.
ARK-series Industrial PLCs
Modular programmable controllers for textile looms, packaging machinery, and chemical batch processes. Frequent issues include SD card corruption in retention modules, analog input card calibration drift, and Ethernet communication timeouts in multi-node networks.
AH-series HMI Touchpanels
7-inch to 15-inch industrial display units with integrated Modbus/Profibus gateways. Repairs address LCD backlight degradation, resistive touchscreen calibration issues, and communication protocol stack failures.
AC-series AC Drive Controllers
Three-phase VFD modules rated 0.75 kW to 30 kW for pump and fan motor speed control. Common faults include IGBT module burnout due to DC bus transients, thermal sensor malfunction, and parameter memory loss after power surges.
AR-series Remote I/O Modules
Distributed digital and analog input/output stations for multi-point sensor networks across large production floors. Failure modes include relay coil burnout, opto-coupler degradation in wet environments, and CAN bus transceiver faults.
AS-series Safety Controller Modules
SIL-rated safety logic modules for emergency stop circuits and interlock monitoring in pharmaceutical and chemical plants. Repairs involve safety relay diagnostics, redundancy self-test circuit analysis, and SIL certification re-validation.

Common AUTORK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTORK equipment arriving at our workshop.
- ✓AK Servo Drive Encoder Communication Loss — AUTORK AK-series drives communicate with encoders via differential SSI or CANopen. Vibration-induced connector corrosion, shielded cable damage near motor terminals, or encoder supply voltage collapse under high current transients causes 'ENC_ERR' or 'Pos_Fault' codes.
- ✓ARK PLC SD Card Data Corruption — AUTORK ARK controllers store programs and retention data on microSD cards. Abrupt power loss, electrostatic discharge, or card slot degradation causes file system corruption and boot loop. Error code 'SD_CORRUPT' or inability to load program from retention memory indicates this fault.
- ✓AC Drive VFD IGBT Module Short Circuit — AUTORK AC-series drives use 6-IGBT three-phase bridge modules rated for continuous switching. Transient overvoltage from sudden motor deceleration, load dumps, or DC bus under-capacitance causes catastrophic IGBT junction failure. Symptoms include tripped overcurrent, DC bus collapse, and potential cabinet fire risk.
- ✓AH HMI Touchscreen Calibration Drift — AUTORK AH-series panels use resistive touch sensors subject to mechanical wear and humidity-induced dielectric degradation. Multi-year textile mill or food plant operation causes touch offset — user must press offset from displayed touch point. Typical failure rate is 3-5 mm drift annually in humid environments.
- ✓ARK Modbus/Profibus Communication Timeout — AUTORK ARK PLCs in multi-node networks experience intermittent slave node timeouts. Root causes: RS-485 termination resistor failure, 120-ohm stubs from old wiring, shielded cable grounding problems, or Ethernet gateway protocol stack memory leak under high message load.
- ✓AK Servo Drive Thermal Shutdown During High-Speed Cycles — AUTORK AK drives with undersized heatsinks or poor cabinet ventilation overheat during sustained 1-2 kHz PWM switching in textile looms and injection molding machines. Thermal sensor drift or faulty sensor contact causes premature shutdown. Symptom: drive halts mid-cycle with thermal warning, production loss.

Frequently Asked Questions — AUTORK Repairs
Do you repair AUTORK equipment anywhere in India?+
Yes. Synchronics repairs the full AUTORK product range — servo drives, PLCs, HMI panels, AC drives, and safety modules across all of India. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bangalore, and all other industrial cities. All repairs are performed at our Vadodara, Gujarat facility with same-day diagnostic reports and 5-7 day turnaround for critical equipment.
How do you handle AUTORK firmware updates and SIL certification validation?+
AUTORK safety modules (AS-series) and PLC controllers require firmware validation after repair. Synchronics maintains licensed AUTORK development tools and accesses official firmware repositories. We download the latest stable release, validate SIL-rated configurations using certified simulation software, and perform functional safety testing per IEC 61508 before return. For safety-critical installations, we provide third-party SIL re-validation certificates on request.
What is your typical turnaround time for AUTORK AK servo drive repair?+
AUTORK AK-series servo drives are diagnosed within 24 hours of arrival. Simple faults like encoder connector repair or firmware reload are fixed within 2-3 days. Complex failures involving IGBT replacement, heatsink upgrade, and multi-stage calibration typically take 5-7 days including full load testing and documentation. We offer 48-hour rush service for production emergencies — contact our operations team for availability.
Do you stock AUTORK spare parts inventory?+
Synchronics maintains active inventory of high-demand AUTORK components including IGBT modules for AC-series drives, encoder connectors, SD card slots for ARK PLCs, and touchscreen assemblies for AH-series panels. For obsolete or rare modules, we source directly from AUTORK's Korean headquarters within 10-14 days. All spare parts carry original manufacturer authenticity certification.
Can you repair AUTORK equipment damaged by power surges or lightning strikes?+
Yes. Lightning and three-phase power surges cause cascading failures across servo drives, PLCs, and analog input cards. Synchronics performs comprehensive surge damage assessment including insulation testing, gate driver isolation checks, and DC bus voltage regulation analysis. We replace surge-damaged semiconductors, upgrade input filtering and transient suppression, and install surge-rated DC-DC converters. Post-repair equipment is tested under actual manufacturing power conditions to verify resilience.
How do I send my AUTORK 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 AUTORK 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 AUTORK 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 AUTORK 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.
