Guide to Siemens Simodrive 611 Control and Regulation Boards 6SN1110 – 6SN1112 – 6SN1116

What Is a SIMODRIVE Control Board and What Is It Used For?

Within Siemens SIMODRIVE 611 industrial automation systems, the Control and Regulation Boards are the electronic components that extend, specialize, and optimize the functions of the Closed-Loop modules.

They are the system’s “additional intelligence”: they handle advanced logic, synchronization, communication, and dedicated functions that are not managed by the power modules or the Closed-Loop modules.

In practice, the Control Boards are what allow a CNC system to become: more precise, more versatile, faster, and more integrated with the machine.

⚙️ The Family Roots: 6SN1110 / 6SN1112 / 6SN1116

The boards of the SIMODRIVE family derive from three main series, each dedicated to a specific type of control requirement.


🔹 6SN1110 – Basic Peripheral Boards

These boards extend I/O functions and add capabilities such as:

  • field signal management

  • support for peripheral logic

  • interfacing with the Closed-Loop Unit

  • expansion of the drive’s basic functions

💡 Ideal for standard multi-axis configurations that require I/O expansion.

🔹 6SN1112 – Synchronization and Axis Regulation Boards

Designed for advanced motion functions, including:

  • axis synchronization

  • spindle control

  • management of additional encoders

  • enhanced regulation cycles

💡 Perfect for machining centers, lathes, and high-precision multi-axis lines.

🔹 6SN1116 – Advanced Control / Motion Control Boards

The most advanced boards of the SIMODRIVE family:

  • complex motion management

  • real-time dynamic regulation

  • industrial communication options

  • special functions for custom automation

💡 Ideal for special machines, high-performance systems, and complex multi-drive architectures.

🎯 Root Function: Enhancing the Closed-Loop Units

All 6SN1110 / 6SN1112 / 6SN1116 boards share the same purpose:

👉 Expanding or integrating the functions of the Closed-Loop Units (6SN1117 / 6SN1118).

They are used when a machine requires:

  • additional specific functions

  • high-precision synchronization

  • customized logic

  • extra connections or I/O

  • advanced motion not manageable by the Closed-Loop module alone


🏭 Industrial Applications – Siemens SIMODRIVE Command & Regulation Boards

SIMODRIVE Control Boards are used in:

  • CNC machining centers (SINUMERIK 810D / 840D / 840Di)

  • multi-axis machines

  • milling machines, lathes, grinding machines

  • cartesian robots and pick-and-place systems

  • automated industrial lines

  • special machines and custom plants

They are essential for applications requiring coordination, flexibility, and high precision.
