1.1 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.
The MICROMASTER 440 can be used in both 'stand-alone' applications as well as
being integrated into 'Automation Systems'.
