Industrial Applications

1. Industrial Conveyor Systems and Material Handling

Precise speed and torque control for heavy-duty material conveyors, using sensorless vector control to maintain high torque at low speeds under fluctuating load conditions.

Problem Solved

Heavy-duty start-ups often cause motor stalling or belt slippage. The drive’s 150% overload capacity for 60 seconds (up to 36 A transient current in Heavy Duty mode) ensures reliable high-torque startup.

2. Industrial Fan and Ventilation Control (HVAC)

Modulation of fan speed in massive industrial ventilation or cooling towers using the 15 kW Normal Duty rating to dynamically adjust airflow while optimizing energy consumption.

Problem Solved

Fixed-speed industrial fans run continuously at peak capacity, resulting in high energy consumption and mechanical wear. Adjusting speed according to process demands cuts consumption and reduces noise.

3. Manufacturing Machinery (Textile and Ceramic Extruders)

Controlling production machines such as textile spin-frames or ceramic extruders, utilizing Modbus RTU via RJ45 to seamlessly tie into the main PLC system.

Problem Solved

Harsh industrial environments with chemical or dust pollution can cause premature drive failure. The ATV310 features high resilience to chemical pollution (class 3C3) and dust (class 3S2), safeguarding the electronics.
