Variable-speed Drives for Decentralised Tasks The MICROMASTER 411/COMBIMASTER 411 products are ideally suited to decentralized drive applications which have the requirement for high IP protection rating. The modular design of the MICROMASTER 411/COMBIMASTER 411 allow the user to select the product components individually, including options. All the modules, starting from the series of basic units, are easy to install and wire up. Various communication modules are available, such as the PROFIBUS and AS-Interface module. Braking functions are implemented by the EM module (electromechanical brake control module) and an REM module (resistor brake and electromechanical brake control module).
Typical Uses
It has been designed for use in a broad range of drive applications from simple  individual pump or fan applications up to multiple drive conveyor applications  incorporating networked control systems.
