MICROMASTER 411 and COMBIMASTER 411 - Standard
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.
