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.
