Central drive systems with SIMODRIVE 611

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.

The SIMODRIVE 611 converter system is designed for operation in industrial environments in grounded TN-S and TN-C systems (VDE 0100, Part 300). For other network configurations, an upstream

transformer with isolated windings must be used on the secondary side in a star connection with grounded neutral point (YN connection group). For voltage matching to other line supply voltages,

matching transformers in economy circuit can be used for TN-S and TN-C systems. You can find transformer types matched to the SIMODRIVE 611 infeed modules under Line interfaces for voltage


The infeed modules contain a 6-pulse three-phase bridge connection (B6). Ensure that compatibility is maintained for operation on residual-current protective devices (EN 50178/VDE 0160 Section; Type B).

The line filters assigned to the 16 kW and 36 kW I/R modules will restrict the leakage currents to below 150 mA.

As an alternative, an isolating transformer with secondary-side YN connection must be used in conjunction with another protective measure (N connected to housing) against hazardous leakage

currents to disconnect residual-current systems which do not achieve the compatibility required.


For satisfactory and reliable operation of the drive system, original components of the SIMODRIVE system and the original Siemens accessories as described in this catalog and in configuration

manuals, functional descriptions or user manuals should be used.

The user must observe the configuring instructions.

Combinations that differ from the configuring instructions – also in conjunction with non-Siemens products require a special agreement.

If no original components are used, for example for repairs, approvals such as UL, EN, Safety Integrated, etc. can become invalid and thus the operation authorization for the machine with the

non-Siemens components installed becomes invalid.

All of the approvals, certificates, declarations of conformity, test certificates, e.g. CE, UL, Safety Integrated etc. have been performed with the associated system components as they are described

in the catalogs and configuration manuals.

The certificates are only valid if the products are used with the described system components, are installed according to the installation guidelines and are used for their intended purpose.

In other cases, the vendor of these products is responsible for arranging that new certificates are issued..

The SIMODRIVE 611 converter system consists of:

  • 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
  • HFD line reactors with damping resistor
  • Special modules
  • Supplementary system components

Various cooling methods are available for the power-dependent infeed and drive modules:

  • Internal cooling
  • External cooling
  • Hose cooling for 300 mm wide modules


Easy handling, simple assembly and wiring are among the main requirements to be fulfilled by the design of the converter modules. As a result of the consistent 50 mm mounting grid and the connection of power, signal and bus cables, it is possible to implement customer-focused solutions.

  • Width of all modules in 50 mm (1.97 in) grid
  • Height of all modules is 480 mm (18.90 in)1)
  • Depth of the modules without connectors and optional mounted accessories referred to the mounting surface is:
  1. mm (11.34 in) with internal cooling or hose cooling
  2. mm (9.09 in) with external cooling2)
