SINAMICS S120 - technology functions


SINAMICS S120 provides comprehensive Standard and Advanced Technology Functions that substantially expand the application range of SINAMICS drives. These functions are not connected permanently and immutably, but can be interrupted at defined intervention points and newly interconnected / wired. This opens up the possibility for positioning, controlling the process variables and special tasks as well as logically and arithmetically combining signals in the sequence control and in the drive control loops. In this way, you can achieve the optimum solution for the task in hand.

Basic positioner (EPos)

SINAMICS S120 - basic positioner (EPos)

The basic positioner (EPos) in SINAMICS S120 is part of the Standard Technology Functions and means integrated functionality for absolute and relative positioning of linear and rotary axes with motor encoders and/or machine Encoders.

EPos - integrated positioning functions

With the EPos integrated positioning functions, an additional, higher-level controller is no longer required for many positioning applications. Moreover, this integrated functionality is also extremely flexible: It can be used for highly dynamic servo control as well as for more simple applications with vector-controlled induction motors. Up to 64 target positions along with their respective traversing speeds can be permanently stored in the drive during commissioning. Positioning can be defined either absolutely or relatively. It is also possible to transfer these parameters as required from a higher-level PLC, which is optimally supported by the SINA_POS block from the drive library.
This means that target positions and velocities can even be changed on-the-fly during a positioning run.

Technology controller (PID)

SINAMICS S120 - Technology controller (PID)

The technology controller (PID controller) in the SINAMICS S120 is part of the Standard Technology Functions and permits all types of simple process controls to be implemented.
It can be used, for example, to control the line pressure, filling level, temperature, flow or also tension control or load balancing.

SINAMICS Technology Extensions (SINAMICS TEC)

SINAMICS Technology Extensions (SINAMICS TEC)

SINAMICS Technology Extensions (SINAMICS TEC) are configurable functions or Siemens technologies that can be added to extend firmware functions. This technology is part of the Advanced Technology Functions and is also known as Open Architecture (OA) Application.
Siemens provides SINAMICS TEC for high-performance application-specific and targeted tasks. For example, for applications in logistics with storage and retrieval machines, on test stations, for simple communication, and in multi-winding motors.

SINAMICS TEC – configurable extensions for use in special tasks

  • With SINAMICS TEC POLYGON (Polygonal Line), for example, in test station technology, master-value-dependent characteristics can be injected as profiles into torque or speed setpoints to simulate internal combustion engines.

  • With SINAMICS TEC SETPGEN (Setpoint Generator), a time-dependent signal generator with different curve functions is available, which is also used in test station technology.

  • The SINAMICS TEC VIBX (Vibration Extinction) enables reduction of mechanical vibrations in storage and retrieval machines with a reference variable filter (setpoint filter).

  • The SINAMICS TEC OALINK (Open Application Link) provides a simple extension of the CU320-2 communication via DRIVE-CLiQ. It can be used to exchange a large volume of data bidirectionally between two CUs.

  • The SINAMICS TEC SERVCOUP (Servo Coupling) enables the coupling of multi-winding motors or segment motors to an encoder in the SERVO control mode.


SINAMICS Drive Control Chart (SINAMICS DCC) enables you to create your own and complex technology functions based on graphical signal processing charts with interconnected blocks. By simple graphical configuration, the device functionality can be individually expanded with closed-loop control, mathematical, and logic functions.
This technology function is part of the Advanced Technology Functions and is available in the SINAMICS S120.

Optimal adaptation to the drive task

SINAMICS Drive Control Charts provide a way of configuring technological functions for the drive system freely in the simplest way. This gives users a new dimension in individual adaptability to the specific drive tasks of their machine. With Drive Control Charts (DCC), extensive blocks are available in libraries, so-called Drive Control Block libraries (DCB libraries), for configuration. With the DCC Editor, the multi-instance-capable blocks can be graphically connected by drag and drop to define open and closed-loop control functionalities. DCC does not limit the number of functions that can be used. The number of functions is limited only by the performance of the target platform. Variables of the Drive Control Charts can be published as SINAMICS parameters and fitted into the control structure at any point by means of SINAMICS BICO technology. SINAMICS DCC is an option for the commissioning software STARTER.

There are two types of DCB libraries that can be used for configuration with the DCC Editor: DCB Standard and DCB Extension.

DCB Standard is the standard library with a comprehensive selection of closed-loop control, mathematical, and logic blocks, and is available immediately on installation of SINAMICS DCC.

DCB Extension are library expansions that can expand the range of blocks with separate libraries. These include the GMC and Math Extended libraries, which are supplied as application examples.

Moreover, via DCB Extension, you can program your own blocks in the high-level language C/C++ for user-specific requirements. You program and develop blocks as your own library in a separate tool, SINAMICS DCB-Studio. This enables users to program their own drive-oriented functions in the drive efficiently.
