Looking Inside the Siemens Sinamics SME20/25 and SME10/125 Encoder

The encoder system is connected to the SINAMICS S120 via DRIVE-CLiQ. Motors with DRIVE-CLiQ interfaces are designed for this purpose. These motors simplify commissioning and diagnostics because the motor and encoder type are identified automatically. The Sensor Modules(SME20, SME25, SME120, and SME125) are only to be used with machines and may ONLY be connected to the DRIVE-CLiQ interfaces of proprietary components. Direct encoder systems outside the cabinet can be connected to the Sensor Modules External. The SMEs evaluate these encoder systems and convert the calculated values to DRIVE-CLiQ. No motor or encoder data is stored in the Siemens SMEs. The Sensor Modules External provides the encoder power supply. The power supply for the SME is provided from the connected DRIVE-CLiQ cable. This should be taken into consideration when selecting the DRIVE-CLiQ cable. SMEs have a higher degree of protection(IP67) which means it is suitable to be installed on the outside of the cabinet.

Part numbers for the SMEs include:
