Industrial Applications

1. Conveyor Systems with Frequent Starts/Stops

The PM240-2 is ideal for controlling conveyor belts in manufacturing or logistics. Its dual overload capability (15kW LO, 11kW HO) allows for efficient continuous operation while providing necessary power bursts for starting heavy loads or managing jams. The integrated braking chopper ensures controlled and rapid deceleration for precise positioning or emergency stops.

Problem Solved

Prevents mechanical shock and wear on conveyor components during starting and stopping, ensures precise material handling, and allows for quick, safe halts under varying load conditions, extending equipment lifespan and improving operational efficiency.

2. Industrial Pump or Fan Control in HVAC/Water Treatment

This power module can efficiently drive pumps or fans in industrial HVAC systems, water treatment plants, or fluid circulation systems. The 15kW (Low Overload) rating is well-suited for the continuous, relatively stable loads typical of pump and fan applications. The Class A filter helps maintain EMC compliance in environments sensitive to electrical interference.

Problem Solved

Provides energy-efficient speed control for fluid handling, reducing operating costs, noise, and wear on mechanical components. The integrated Class A filter minimizes electromagnetic interference, crucial for sensitive control environments and compliance with industrial standards.

3. Automated Machine Tools (e.g., Grinding Machines)

For machine tools requiring precise speed and torque control, such as grinding machines or small CNC equipment, the PM240-2 offers vector control up to 200 Hz and high overload capacity (11kW HO). This ensures dynamic response and sustained torque even during demanding machining operations. Its compact size (FSC) allows for integration into control cabinets where space is often limited.

Problem Solved

Delivers accurate and responsive motor control for machining processes, handling sudden load changes without compromising performance or causing production halts. The IP20 rating requires cabinet installation, protecting sensitive electronics from the harsh workshop environment while ensuring precise operation.
