1.1 MICROMASTER 411 / COMBIMASTER 411
The Siemens COMBIMASTER 411 & MICROMASTER 411 variable frequency (V/f)
range of inverters are used to control the speed of three phase AC induction
motors.
COMBIMASTER 411 provides for a ready to use Inverter/Motor combination unit
MICROMASTER 411 offers an Inverter for adaptation to a compatible motor with
terminal boxes of size GK030.
Inverters are available in ranges 370 W to 3.0 kW 380/480 V AC for three phase
units.
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 411 / COMBIMASTER 411 is
suitable for many variable speed applications. Using the functionally grouped
parameters, the MICROMASTER 411 / COMBIMASTER 411 can adapted to more
demanding applications.
MICROMASTER 411/COMBIMASTER 411 can be used in 'stand-alone' applica-
tions as well as being integrated into complete automation systems.
