General configuration sequence
The function description of the machine provides the basis for the configuration. The definition of the components is based on physical dependencies and is usually carried out as follows:
|
Step

Configuration begins with the mechanical interface to the machine. A suitable motor is selected according to the specified torques and speeds. A matching power unit is then also chosen. Depending on the requirements of the machine, the motor is supplied as a single drive via a Power Module or within a multi-motor drive group via a Motor Module. Once the basic components have been defined, the system components for matching to the electrical and mechanical interfaces are selected.
The SIZER for Siemens Drives engineering tool (integrated in the TIA Selection Tool) allows the correct components to be selected quickly and easily. Based on the torque and speed characteristics entered, SIZER for Siemens Drives (integrated in the TIA Selection Tool) guides the user through the configuring process, identifying suitable motors and matching SINAMICS power units and other system components.
The following sections describe those SINAMICS S120 components which are needed to create a drive system subject to certain boundary conditions. For information about individual components, please also refer to the online help of the SIZER for Siemens Drives engineering tool (integrated in the TIA Selection Tool).
