New software-based drive functions from Siemens

January 2015 Motion Control & Drives

Siemens has extended the range of applications for its Sinamics S120 drives family with new, software-based advanced technology functions. The specific functions concerned are synchronous operation (1:1 or with gear ratio), camming, and positioning of the synchronous axes. The new functions are part of the DCB (drive control block) extension function block library GMC (general motion control), which is available for downloading from the Siemens Industry Support web pages. The advanced functions allow users to extend their existing or new Sinamics S120 drive systems with new application-specific functions. In addition, drive-related control and adjustment tasks can be transferred from the controller to the drive, making it possible to protect critical process knowledge effectively against unauthorised access.

The DCB extension function block library and the new functions can be installed quickly and easily on the Sinamics S120 drives via the graphical user interface of the DCC (drive control chart) editor, part of the starter commissioning software. To access the full range of advanced technology functions, users must activate a chargeable licence on the drive.

In addition to the motion functions now being exhibited, Siemens plans to offer even more functions for its Sinamics S120 drives in the future, ranging from further DCB extension function block libraries through to an open architecture interface and application-specific functions for hydraulic servo pumps or sway controls.

The DCB extension function block libraries are created using the DCB Studio software. Customers can purchase the DCB Studio to develop their own functions, or can commission Siemens to create specific module libraries and functions for them.
