MICROMASTER 440

The powerful all-rounder

The domain of drives is forever influenced by forces that are difficult to control. It would hence take the most powerful of frequency inverters to meet the diverse challenges simultaneously. The MICRO- MASTER 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.
