6SL3040-0MA00-0AA1 SIMATIC PLC

The Siemens 6SL3040-0MA00-0AA1 is the CU320 Control Unit for the SINAMICS S120 modular drive system. It serves as the central intelligence for multi-axis drive configurations, coordinating closed-loop control and drive functions across connected Motor Modules and Line Modules via the DRIVE-CLiQ interface. This control unit is designed for applications requiring centralized control of multiple drive axes in a shared DC link configuration. It supports PROFIBUS DP communication and includes 4 DRIVE-CLiQ ports for connecting power modules and encoder interfaces. The unit is supplied without a CompactFlash card, which is required for operation and must be ordered separately.
