Siemens: Decentralized Servo Drive

The Sinamics S120M is a motor with integrated drive that offers the option of moving the inverter outside the control cabinet and directly onto the motor, reducing cabinet space and required cooling.

The decentralized axes are connected back to the central S120 components in the cabinet via a hybrid cable and adapter module. The pre-assembled hybrid cable contains all encoder and power cables and serves multiple axes through a daisy chain connection; this single-cable solution reduces the number and length of cables and is easily expanded for additional axes. All existing Safety Integrated functions and communication options are available, and the benefits of power sharing between axes across the DC bus are completely realized. Other features include a synchronous servomotor with multi-turn absolute encoder, optional holding brake and an integrated power unit (motor module) available in three shaft heights covering the power range of 0.25 to 1.5 kW. Typical applications include packaging, printing, glass, textile and other processes, where machinery and production lines require multiple servo axes in a space-restricted environment.
