6SL3040-1LA01-0AA0 SINAMICS S120 CU310-2 PN Control Unit PROFINET | Siemens

The Original New Siemens 6SL3040-1LA01-0AA0 SINAMICS S120 CU310-2 PN Control Unit is a high-performance single-axis drive controller for the SINAMICS S120 modular drive system. Designed for the communication, open-loop, and closed-loop control functions of one Power Module, this control unit supports PROFINET IO with PROFIdrive V4 profile for seamless integration into industrial automation networks. The CU310-2 PN features an onboard encoder evaluation interface (TTL/HTL/SSI), 11 digital inputs, 1 analog input, and a DRIVE-CLiQ interface for communication with system components. The unit is supplied without a CompactFlash card, which must be ordered separately to store firmware and parameter settings. Part of the SINAMICS S120 drive system, this control unit is suitable for precise motion and drive control in demanding industrial environments.
