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 &＃39;stand-alone&＃39; applications as well as

being integrated into &＃39;Automation Systems&＃39;.
