Siemens expands its servo-drive system for manufacturing applications

Siemens is extending its drive portfolio in the extra-low-voltage range for 24-48V EC motors with its new Simatic Micro-Drive.

The new product line with UL- and CE-marked components consists of the PDC (Profidrive Control) servo drive in conjunction with a range of motors and connecting cables from product partners, along with the TM (technology module) format with servo and stepper drives in compact 20mm width that can be used in conjunction with distributed or open controllers. 

Simple connectivity to Siemens programmable logic controllers (PLCs) helps reduce the engineering workload, while integration into Siemens automation technology via its TIA Portal makes for simple commissioning and servicing. Attributes such as smart encoders and one-button tuning add to its plug-and-play startup. Communication takes place over PROFINET using PROFIsafe and PROFIdrive profiles. The new Safety Integrated function SLT (Safely Limited Torque) limits torque by monitoring motor current in running operation. 

To address its customers’ requirements with maximum flexibility, Siemens utilises product partnerships with companies such as Dunkermotoren, ebm-pabst, Harting and KnorrTec when it comes to the motors and cables used with Micro-Drive. Other third-party motors can also be utilised with support for various encoder types. 

Simatic Micro-Drive PDC focuses on higher performance applications with 100W and 600W units that permit side-by-side rail mounting. 

Simatic Micro-Drive TM units are designed for basic performance in industries with a focus on compactness and safety requirements. In addition to servo, TM units feature new modules that aim to control stepper motors with or without incremental encoders. Machine builders and users should benefit from a compact design, easy wiring and installation to ensure top performance.   

The Siemens Totally Integrated Automation (TIA) Portal is used to configure drives and motors quickly and easily including the activation of safety functions with a Fail-safe PLC via PROFIsafe. Machine operating data can be transmitted directly to the controller from Micro-Drive and transferred to Cloud-based platforms such as MindSphere over MindConnect.
