Enhanced SINAMICS Control Unit for Variable Speed Drives
Press release date: November 5, 2013
New CU250S-2 control unit now in stock; supplements existing Siemens G120 drive with universal vector control and encoder feedback
Siemens Industry, Inc. announced today the availability of the new Sinamics CU250S-2 control unit for use with its popular Sinamics G120 variable speed drives. The unit provides vector control with encoder feedback. Additionally, the operation of single-axis applications with exact speed and torque control on induction motors, as well as positioning tasks with high demand on I/O, are supported, with different encoder interfaces provided on the module. These new units complete the G120 product portfolio and replace the CU240S with encoder interface.
Typical applications for these new control units include single drives with a large number of I/O or those with high speed control requirements, including extruders, centrifuges, wire-drawing machines, basic fabric webs, conveyors, lifters and others in markets ranging from automotive assembly, textiles, printing and chemical processing to nearly all conveyors and material handling.
The new Sinamics CU250S-2 control units can be combined with existing power modules to support all G120 drive applications, with or without encoder evaluation, for demanding applications requiring speed feedback. Additionally, STO (Safe Torque Off), SBC (Safe Brake Control) and SS1 (Safe Stop 1) features are all integrated, enabling their application on basic safety requirements. With the purchase of an optional software license, extended safety functions can be obtained, along with software for a single positioning function (EPos).
Comprehensive communications interfaces for general machine building are provided on this new Sinamics control from Siemens, including Profibus DP, Profinet (Ethernet I/P), RS485 (USS protocol, Modbus RTU) and CANopen, allowing convenient connection to other Siemens systems as well as external automation systems. No external gateway is needed.
Other features include an integrated USB port, so users can simply go online to facilitate engineering set-up and maintenance, plus an integrated slot for an SD card to allow simple cloning and firmware updates or upgrades.
