AUTO-TEK Product Lines We Repair
Our engineers are trained on the full AUTO-TEK product range. Below are the major product families we service.
AT-Drive Series (Variable Frequency Drives)
Scalable VFD platform for motor speed control and energy optimization. Common issues include capacitor bank failures, IGBT gate driver faults, and control board microcontroller corruption from voltage spikes. Synchronics rebuilds AT-Drive boards with genuine component replacement and thermal re-profiling.
AT-Motion Servo Controllers
Closed-loop servo drive platform for precision positioning and coordinated multi-axis motion. Typical faults include encoder signal loss, PID tuning drift, and phase leg short circuits. Synchronics recalibrates servo loops and replaces faulty power modules with AUTO-TEK-equivalent assemblies.
AT-Logic PLC & HMI Modules
Compact programmable controllers and human-machine interfaces for factory floor automation. Prone to digital input isolation failures, Ethernet port burnout, and battery-backed memory corruption. Synchronics restores IO functionality and reprograms user applications without firmware loss.
AT-SafeLink Communication Modules
Industrial fieldbus interface cards for Profibus, CANopen, and Modbus integration. Common failures are isolation transformer breakdowns, opto-coupler degradation, and connector corrosion in humid mill environments. Synchronics cleans and replaces isolating components to restore network communication.
AT-PowerBank Capacitor & Filter Units
DC link filtering and harmonic suppression modules used in drive installations. Electrolytic capacitors dry out and ripple current resistors overheat under continuous operation in Indian summer heat. Synchronics retrofits with automotive-grade polymer capacitors rated for 85-105 degC ambient.
AT-Gateway Protocol Converters
Multi-protocol bridge devices for legacy system integration and real-time data exchange. Firmware corruption and EEPROM read errors common in power-cycling scenarios. Synchronics performs JTAG-based firmware recovery and validates protocol conversion tables after repair.

Common AUTO-TEK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AUTO-TEK equipment arriving at our workshop.
- ✓AT-Drive capacitor bank ripple current failure — Electrolytic capacitors in the DC link degrade rapidly in high-ambient-temperature Indian factories (35-45 degC). Poor ventilation in switch cabinets and contaminated cooling fans accelerate capacitor drying, causing ESR rise and bus voltage instability.
- ✓AT-Motion servo encoder signal loss or signal corruption — Long cable runs in noisy factory environments (induction furnaces, spot welders, arc machines) introduce EMI into shielded encoder lines. Improper cable routing through power bundles and cracked connectors break the feedback loop, causing servo faults and position overshoots.
- ✓AT-Logic PLC digital input isolation opto-coupler failure — Industrial input transient spikes and AC line surges stress the opto-coupler die, causing premature aging and light-emitting diode (LED) brightness loss. Worn isolation resistors increase input voltage requirements, making the PLC intermittently miss sensor signals.
- ✓AT-Drive IGBT gate driver circuit malfunction — Thermal cycling of solder joints on gate driver ICs (TL494, UCC27324) from daily motor start/stop transients creates micro-cracks. Bootstrap capacitor failure prevents proper gate bias, causing shoot-through current spikes and IGBT destruction.
- ✓AT-SafeLink Ethernet port burnout and no network communication — Lightning strikes and static discharge (common during monsoon in Indian manufacturing) bypass surge protection and damage the RJ45 connector pins and associated isolation transformer. Phased-out ferrite core materials degrade faster in high-humidity coastal plants.
- ✓AT-Logic PLC battery-backed memory data loss during power outages — The onboard lithium coin cell (CR2032 equivalent) depletes faster in hot cabinet environments and loss of main power triggers backup circuits that drain residual energy. Faulty diodes in the backup power path prevent proper battery isolation.
