Industrial Applications

1. Conveyor Systems for Material Handling

This power module can effectively control the speed and torque of motors driving conveyor belts in manufacturing or logistics facilities. The 2.2 kW (HO) / 3.0 kW (LO) output power is suitable for medium-duty conveyor applications, and the vector control (0-200 Hz) allows for precise speed regulation and positioning. The integrated braking chopper facilitates quick and controlled stopping, crucial for material handling applications to prevent product damage or ensure safety during emergency stops.

Problem Solved

Provides precise speed and torque control for smooth material flow, rapid and controlled deceleration for safety and process accuracy, and efficient operation of conveyor motors.

2. Packaging Machinery

The SINAMICS PM240-2 is ideal for controlling various axes in packaging machines, such as those for filling, sealing, or labeling. The high dynamic performance and precise motor control (vector control up to 200 Hz) allow for rapid acceleration and deceleration cycles, critical for high-speed packaging operations. The integrated braking chopper efficiently dissipates regenerative energy during repetitive braking, ensuring consistent and reliable machine performance.

Problem Solved

Achieves high-speed, repeatable motion profiles for packaging processes, efficiently handles regenerative energy during frequent start/stop cycles, and ensures precise synchronization of machine components.

3. Industrial Pump and Fan Control

For controlling industrial pumps and fans where precise flow or air volume regulation is required. The ability to handle both low overload (3.0 kW) and high overload (2.2 kW) conditions makes it versatile. While IP20 means it needs to be installed in a control cabinet, the internal air cooling supports continuous operation within industrial ambient temperatures (-10 to +50 °C). The V/f control up to 550 Hz allows for efficient operation of centrifugal pumps and fans over a wide range of speeds.

Problem Solved

Enables energy-efficient regulation of fluid flow or air volume, precisely matches pump/fan output to process demands, and extends motor lifespan through soft start/stop capabilities.
