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 a compact 20mm width that can be used with distributed or open controllers. Connectivity to Siemens 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 limits torque by monitoring motor current in running operation.
