Central drive systems with SIMODRIVE 611

Overview

Central drive systems offer a wide performance range based on a modular design. Various closed-loop control units make it possible to combine groups of drives to form a higher-level control system. The 2-axis modules enable space-saving module configurations.

SIMODRIVE 611 is a flexible, energy-saving configurable converter system that is designed to meet the economic and technical demands made on modern machines.With SIMODRIVE 611, Siemens provides a converter system with digital closed-loop controls which meets the highest demands in terms of dynamic response, speed setting range, and smooth running characteristics.

The converter system’s modular design makes it possible to configure drive systems with a virtually unlimited number of axes or main spindles.

The control units are inserted into the power modules.

The power modules are dependent on the power required by the motors. The infeed module is determined by the required DC link power.

The infeed module is used to connect a SIMODRIVE 611 system

group to a low-voltage system with grounded neutral point (TN line supply).

All modules in the SIMODRIVE 611 converter system are of uniform modular design. The interfaces for power supply and communication, as well as the interfaces between control units and power modules, are standardized.

Design

The SIMODRIVE 611 converter system consists of the following

function modules:

Control units adapted to the respective application

technologies and motor types

Power modules

UI or I/R infeed modules

Line filters: Line filters, Wideband Line Filters or

Basic Line Filters
