MM420

MICROMASTER 440
Widely used in logistics systems, the textile industry, elevators, lifting equipment, mechanical engineering, as well as food and beverage and tobacco sectors. Modular design enables flexible expansion and a future-oriented drive concept, allowing users to achieve continuous innovation within the same frequency converter system. Exceptional maintenance and repair friendliness. Applications: Flexible drive suitable for various applications. Fully integrated safety protection functions, the world’s first product with SS1 and SLS features.
With integrated security protection technology, the equipment operates more safely and with greater ease of use.
By integrating security protection functions, the cost of building automated and drive systems with safety protection is significantly reduced. It also effectively ensures human-machine safety. Applications: Production machinery (packaging machines, textile machines), material handling machinery, and others.
PROFIBUS and PROFINET bus standards—the world’s first to integrate these two bus communication protocols directly into frequency converters.
More nodes, diverse network topologies, and higher performance—PROFIBUS and PROFINET’s advantages lie not only in their widespread use by numerous users but also in their optimized engineering and configuration structures. These features enable mature IT technologies to be applied in industrial settings and integrate office tools into industrial control systems.
Application: Remote control of production lines and transmission equipment (e.g., automotive industry).
Regenerative energy feedback capability: within this output power range.
Energy-saving, space-efficient, and free of braking resistors. Utilizing innovative power modules, it enables optimized energy regeneration. Full-power range commutation rectification is achievable without causing any system interference. Additionally, the required line current is minimized, reducing it to 80% compared to conventional frequency converters.
Application: Suitable for driving vehicles, centrifuges, and other production machines with high moments of inertia.
Adopting a new cooling concept, the robustness has been significantly enhanced.
The power module is cooled through external heat sinks, ensuring high cooling efficiency.
The heat dissipation of the power section is entirely accomplished by external heat sinks, while the cooling of the electronic components is achieved through system convection, enabling its use in more demanding climatic conditions. The electronic components are additionally equipped with a robust coating.
Application: Suitable for use in applications with harsh climatic conditions and air pollution (e.g., the textile industry)
