MICROMASTER 411 Standard - MICROMASTER 411 |
Applications
The MICROMASTER 411 products are ideally suited to decentralized drive applications which have the requirement for high IP protection rating. 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.
The products have been based on the MICROMASTER 420 general purpose drive product range.
The MICROMASTER 411 is characterized by its customer-oriented performance and ease of use.
Main Characteristics
- The MICROMASTER 411 supplements the MICROMASTER Integrated product range
- Degree of protection IP66, convection cooling
- The MICROMASTER 411 is characterized by its simple case design
- Electrical isolation between the electronics section in the top part of the case and the terminals in the bottom part of the case
- Parameter sets for reduced commissioning time and cost
- Modular construction with many options
- Operation possible without the need for an operator panel (using jumpers/control potentiometer)
- Integrated, externally accessible control potentiometer
- Compound braking
Design
The modular design of the MICROMASTER 411 allows 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 and electromechanical brake control module).
