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 flexible 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.
SIMATIC Micro-Drive TM units are designed for basic performance in industries with a focus on compactness and simple safety requirements. They are available in 280W-rating and come standard with hardwired Safe Torque Off (STO) safety functions. In addition to servo, TM units feature new modules to control stepper motors with or without incremental encoders.
Both SIMATIC Micro-Drive PDC and TM systems are suited to a range of applications such as automated guided vehicles (AGVs), conveyors, shuttles, storage and retrieval machines for warehousing systems, diverters, assembly machines, and industrial positioning applications.
