The SIMODRIVE 611 drive concept moves the machine towards maximum productivity and flexibility. The Siemens SIMODRIVE 611 drive concept is available from CNC Design . With SIMODRIVE 611, CNC Design provide a converter system with digital closed-loop controls which meets high demands in terms of dynamic response, speed setting range, and smooth running characteristics.

With the SIMODRIVE 611 converter system, customers can combine individual drive systems and easily tune them to the drive performance and the number of axes on machines. SIMODRIVE 611 is a modular transistor pulse converter that enables multi-axis as well as drive combination solutions. Based on its modular design, SIMODRIVE always offers flexible, economic drive solutions tailored to the task at hand.

Over a million drives are in operation with the SIMODRIVE 611 system, especially in machine tools. The SIMODRIVE 611D closed-loop control plug-in unit is suitable for all three-phase motors and offers the suitable drive solution together with SINUMERIK 840D. The SIMODRIVE 611 drive concept is approved to international seals such as CE, EN, CUL, and a wide range of line voltage.

SIMODRIVE 611 consists of several individual function modules. Power-rated infeed modules supply a total power of up to 120kW. SIMODRIVE 611 takes into account different mains power supplies, making it operational all over the world. Large range of mains voltage such as 3 AC 400V, 3 AC 415V, 3 AC 480V are directly operated on TN networks. The SIMODRIVE 611 drive concept is also operated on ‘selective universal current sensitive residual-current protective devices’ in combination with mains filters tuned to the I/RF module (16kW and higher).

Following are the I/RF modules for increased operational safety and a clear reduction of system perturbation:

  • Supplied by the closed-loop power interface modules, the drive axes operate independently of mains tolerances
  • During braking, the excess energy is fed back into the power network for added utility

Following are the cooling methods available for I/RF modules and power modules:

  • Internal heat dissipation
  • External heat dissipation
  • Hose heat dissipation

With the standard solution ‘Internal heat dissipation’, the heat generated by the power loss of the converter components in the electronics and in the power section is dissipated to the interior of the control cabinet. For the external heat dissipation, the heat sinks on the modules are installed through the mounting surface in the control cabinet, allowing the heat from power loss of the power circuit to dissipate to an external ventilation system.

The ‘mechanical interface’, the external heat sink, allows for a degree of protection IP 54. Hose heat dissipation is available for 300mm modules. The heat generated by power loss in the power section is dissipated from the cabinet through flexible hoses. The ‘mechanical interface’ to the ambient air allows for a degree of protection IP 54.

In addition to the 1-axis version, SIMODRIVE 611 drive concept is also available in a 2-axis version. The 2-axis power module enables extremely compact set-ups. The SIMODRIVE 611 drive concept contains a converter system, which mainly consists of infeed modules, power modules and closed-loop control units. The range is rounded off by a number of optional modules.

The SIMODRIVE power modules can be set to accommodate any motor. The SIMODRIVE 611D closed-loop control plug-in unit enables control of all kinds of motors, including synchronous, induction, linear or torque motors, for servo or spindle applications. The induction motors can be operated with or without an encoder depending on the application.

The SIMODRIVE 611D closed-loop control plug-in unit offers the following encoder systems:

  • 2-pole to 6-pole resolvers
  • Incremental encoders with sin/cos 1 Vpp signals and up to 65,535 pulses
  • Absolute value encoder with sin/cos 1 Vpp and EnDat protocol
  • Possible to connect a second, direct measuring system

Aside from such classic drive functions as speed and torque control, SIMODRIVE 611 universal also offers integrated positioning functions in further standard versions, helping to take a considerable load off the controller. In the traversing block editor, customers can store up to 64 independent traversing blocks per axis in plain text. The SimoCom U start-up tool, for example, enables easy entry and storage of the blocks during commissioning. SIMODRIVE 611 drive concept is a modular system that gives customers complete freedom in designing machines.
