MICROMASTER 440

The Powerful All-rounder

Even in the world of drives, there are often forces which are difficult to control. Until the most powerful of our frequency inverters enters the field. The MICROMASTER 440 has been specially designed for those applications which require broader functionality and a greater dynamic response than is usually the case. The sophisticated vector control system ensures a uniformly high drive quality, even when sudden load changes occur. Fast response inputs and positioning deceleration ramps allow movement to target positions even without an encoder. Due to an integrated brake chopper, it works with outstanding precision, even during braking and short declaration ramps. All this is possible within a power range starting at 0.12 kW (0.16 HP) and going up to 250 kW (350 HP).

Typical Uses

Numerous applications in areas such as material handling systems, the textile industry, elevators, hoisting gear, mechanical engineering and the food, beverages and tobacco industries.
