AT CONTROLS Product Lines We Repair
Our engineers are trained on the full AT CONTROLS product range. Below are the major product families we service.
AT Controls VFD Series
Variable frequency drives for AC motor speed regulation and energy optimization. Common issues include IGBT module failure, capacitor degradation, and control board faults causing loss of torque control or random shutdowns during high-speed operations.
AT Controls Motion Control Systems
Servo drive systems and motion controllers for precision positioning in automation and robotics applications. Typical failures include encoder communication loss, servo amp overheating, and axis calibration drift affecting part tolerance and repeatability.
AT Controls PLC and I/O Modules
Programmable logic controllers and distributed I/O systems for industrial automation logic and data acquisition. Common faults include memory corruption, digital input/output card failures, and communication protocol errors in networked environments.
AT Controls Power Distribution Units
Industrial-grade power supplies and distribution boards for multi-axis and high-load applications. Repair challenges include transformer core saturation, rectifier bridge failures, and input voltage regulation issues under unstable Indian grid conditions.
AT Controls HMI and Communication Interface
Human-machine interfaces and gateway modules for real-time plant data visualization and remote monitoring. Typical issues involve touchscreen panel failure, Ethernet port degradation, and firmware incompatibility in legacy installations.
AT Controls Sensor and Encoder Systems
Industrial proximity sensors, rotary encoders, and feedback devices for closed-loop control and speed feedback. Common problems include connector corrosion in humid environments, signal noise interference, and mechanical bearing wear.

Common AT CONTROLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AT CONTROLS equipment arriving at our workshop.
- ✓AT Controls VFD gate driver circuit failure — IGBT gate drive transformers suffer thermal stress and coupling degradation due to Indian ambient heat and industrial dust ingress. Repeated thermal cycling in foundries and forging plants accelerates component aging, causing intermittent gate pulses and drive shutdown.
- ✓AT Controls encoder signal loss and axis drift — Connector oxidation and cable shielding degradation in humid or chemically aggressive textile mills and chemical plants introduce EMI and signal dropout. Mechanical coupling wear in servo systems also causes incremental position errors over time.
- ✓AT Controls PLC memory corruption and program loss — Voltage transients from unreliable Indian power grids, particularly during monsoon season or in areas with frequent lightning strikes, corrupt EEPROM data. Inadequate UPS buffering and poor grounding practices compound the risk of data loss during supply interruptions.
- ✓AT Controls servo drive thermal runaway and shutdown — Heatsink fouling with mill dust, oil mist, or foundry particles restricts airflow and forces passive cooling to fail. Thermal sensor failure also masks rising die temperatures, causing the drive to shut down unexpectedly during peak production hours.
- ✓AT Controls power supply rectifier bridge and capacitor failure — Capacitor aging accelerates under high ambient temperature (common in Indian summer and continuous operation textile plants) and high-ripple current conditions. Rectifier bridge silicon degradation occurs due to repeated voltage transient stress on unreliable power grids.
- ✓AT Controls HMI touchscreen unresponsive or dead — Electrostatic discharge from dry Indian climate damages capacitive touchscreen controller circuits. Salt fog corrosion in coastal plants and humidity-driven connector oxidation interrupt data lines between display panel and main processor board.

What is the typical repair cost for AT Controls VFD gate driver failure?+
AT Controls VFD gate driver repair typically costs INR 8,000 to 15,000 including component replacement, re-soldering, and test. Cost varies by drive power rating and complexity of failure. Synchronics provides free diagnostics and quote within 24 hours of receiving your unit. We also offer warranty of 12 months on gate driver repairs.
Can you repair AT Controls drives that have firmware or software corruption?+
Yes. Synchronics can extract, back up, and restore AT Controls drive firmware using specialized EEPROM readers and re-programming equipment. We also perform CPU module replacement if microcontroller is damaged beyond recovery. All firmware flashing is followed by full functional testing to ensure correct operation with your machinery.
How do you test AT Controls encoder and feedback systems before returning equipment?+
Synchronics tests AT Controls encoder systems using precision function generators and digital oscilloscopes to verify signal quality and frequency response. We simulate load conditions, verify zero-position calibration, and perform 8-hour burn-in runs on servo systems. All encoders are tested within 0.05 degree accuracy before dispatch.
