Siemens 6SL3040-1MA00-0AA0 DP Control Unit Module

Siemens 6SL3040-1MA00-0AA0 CU320-2 DP Control Unit is the SINAMICS S120 drive-system control module that coordinates multiple drives over PROFIBUS DP, delivering centralized command and sequencing while shipping without a Compact Flash Card. Designed for 24 V DC operation, the unit specifies a nominal supply of 24 V with a practical range of 20.4 to 28.8 V, draws about 1.0 A under typical load, and dissipates roughly 24 W; DRIVE-CLiQ cabling supports lengths up to 100 meters. Key electrical limits include a total maximum permissible output current of 5.5 A, which governs how many drive modules and I/O loads can be connected in a single DP network, making this module suitable for compact to moderately sized SINAMICS S120 installations. As a DP-variant control unit, CU320-2 DP serves applications requiring PROFIBUS DP integration with a Siemens automation stack, such as packaging, textiles, and material handling, where reliable bus communication and motion control synchronization across drives are essential.
