Versatile new control unit for variable speed drive
Typical applications for these new control units include single drives with a large number of I/O, or those with high speed control requirements (e.g., extruders, centrifuges, wire-drawing machines, basic fabric webs, conveyors, lifters, etc.).
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 software for a single positioning function (EPos) are available with the purchase of an optional license.
Comprehensive communications interfaces provided on the CU250S-2 include Profibus DP, Profinet (Ethernet I/P), RS485 (USS protocol, Modbus RTU) ,and CANopen. No external gateway is needed. Other features include an integrated USB port, and an integrated slot for an SD card to allow simple cloning and firmware updates or upgrades.
