SIEMENS MICROMASTER 440 – Drive Technologies

In the world of automation, there are certain applications which require broader functionality and a greater dynamic response. The Siemens MICROMASTER 440 is a general purpose AC vector drive specially designed for these applications. The sophisticated vector control functionality ensures precise speed control, even when sudden load changes occur. An integrated brake chopper and ability to stop at a target position without an encoder, ensures outstanding precision, even during braking and short declaration ramps. All this is possible from 0.16 HP through 350 HP (0.12 to 260 KW).

Standard Features

  • Speed Control, Torque Control

The MICROMASTER 440

The MICROMASTER 440 are frequency inverters for speed and torque control of three-phase motors. The various models available cover the performance range from 120 W to 200 kW (for constant torque (CT), alternatively up to 250kW (for variable torque (VT)).
The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A special pulse-width modulation method with selectable Pulse frequency permits quiet motor operation. Comprehensive protective functions provide excellent inverter and motor protection.
With the factory default settings, the MICROMASTER 440 is suitable for many variable speed applications. Using the functionally grouped parameters, the MICROMASTER 440 can adapted to more demanding applications.
