Siemens 6SL30401MA00-0AA0 Control Unit DP Module

Siemens 6SL30401MA00-0AA0 SINAMICS Control Unit CU320-2 DP with PROFIBUS interface (without Compact Flash card) is a dedicated CU320-2 DP controller for SINAMICS S120 drive modules, handling the drive’s communication and control functions with a PROFIBUS DP connection to the higher‑level controller. This DP variant is specified for operation within SINAMICS S120 systems and is delivered without a CompactFlash card. The unit supports 12 digital inputs with an input range of -3 to 30 V, where low level is -3 to 5 V and high level is 15 to 30 V; at 24 V DC supply, typical input current is 3.5 mA, with signal delay times of about 50 µs for L→H and 150 µs for H→L transitions. Environmental ratings show 0 to 55 °C operating temperature and -25 to 55 °C storage temperature, with a maximum relative humidity of 95% at 40 °C during transport. In system architecture, the CU320-2 DP executes the drive control logic for SINAMICS power modules and communicates with automation networks via PROFIBUS DP, providing a compact, firmware‑driven control point within motion and automation applications. This model is commonly selected when PROFIBUS DP compatibility is required for SINAMICS S120 setups, delivering reliable control for precise motion tasks in manufacturing environments where robust, field‑proven integration is essential.
