Integration of SINAMICS S120M into the SINAMICS S120 drive system

Modular system for complex drive tasks

SINAMICS S120 solves complex drive tasks for a very wide range of industrial applications and is, therefore, designed as a modular system. Users can choose from many different harmonized components and functions to create a solution that best meets their requirements.

The powerful SIZER for Siemens Drives configuration tool makes it easier to choose and determine the optimum drive configuration.

SINAMICS S120 optimally supports:

• Synchronous and asynchronous motors
• Linear and torque motors
• SINAMICS S120M

System architecture with a central Control Unit:

On the SINAMICS S120, the drive intelligence is combined with closed-loop control functions into Control Units. These units are capable of controlling drives in the vector, servo and V/f modes. They also perform the speed and torque control functions plus other intelligent drive functions for all axes on the drive. Inter-axis connections can be established within a component and easily configured in the STARTER commissioning tool using a mouse.

Functions for higher efficiency

• Basic functions: Speed control, torque control, positioning functions
• Intelligent starting functions for independent restart after power supply interruption
• BICO technology with interconnection of drive-specific DI/DOs for easy adaptation of the drive system to its machine environment
• Integrated safety functions for rational implementation of safety concepts
• Regulated infeed/regenerative feedback functions for preventing undesirable reactions on the supply, allowing recovery of braking energy and ensuring greater stability against line fluctuations.

DRIVE-CLiQ – the digital interface between SINAMICS components

The SINAMICS S120 components, including the motors and encoders, are interconnected via a joint serial interface called DRIVE-CLiQ. The standardized cables and connectors reduce the variety of different parts and cut storage costs. Encoder evaluations for converting standard encoder signals to DRIVE-CLiQ are available for third-party motors or retrofit applications.

Electronic rating plates in all components

An important digital linkage element of the SINAMICS S120 drive system are the electronic rating plates integrated in every component. They allow all drive components to be detected automatically via DRIVE-CLiQ wiring. As a result, data do not need to be entered manually during commissioning or component replacement – helping to ensure that drives are commissioned successfully!

The electronic rating plate contains all the relevant technical data about that particular component. In the motors, for example, this data includes the parameters of the electric equivalent circuit diagram and characteristic values for the built-in motor encoder. In addition to the technical data, the rating plate includes logistical data (manufacturer ID, article number, and ID). Since this data can be called up electronically on site or remotely, all the components used in a machine can always be individually identified, which helps simplify servicing.
