SINAMICS servo drives

SINAMICS servo drives have been designed for applications where motion control functions must be quickly and precisely controlled. From simple position moves to high speed coordinated multi-axis systems including kinematics, Siemens offers the exact fit across the largest product spectrum. Other features that set SINAMICS servo drives apart include innovative drive based safety technology, consistent integrated engineering tools, and the high level of integration with SIMATIC controllers and Siemens TIA Portal, allowing drag and drop configuration and leading-edge simulation capabilities

Overcurrent Protection (OCP), short-circuit current rating (SCCR) & a new UL Standard for VFDs,
UL 61800-5-1: What you Need to Know


Join us for this webinar where we explain different types of overcurrent protective devices (OCPD), their behavior in circuit protection, and differences among them. This presentation highlights the requirements of motor branch circuit protection according to different standards as well as according to NEC/NFPA 70 for industrial control panels & variable frequency drives. The presentation also provides practical understanding of short-circuit current rating (SCCR) as well as OCPD sizing to obtain a desired SCCR for overall equipment or industrial control panel in compliance with UL/NEC/IEC.


As a bonus, a new UL standard, UL 61800-5-1 for VFDs will be discussed along with its impact to the industry & benefits to the users/OEMs/Panel builders. In addition, the strong benefits of using SINAMICS drives will be demonstrated from the product safety point of view which will help users/equipment owners reduce total cost of ownership through potential savings due to improved product safety and enhanced OSHA compliance.
