Siemens 6SL3040-1MA00-0AA0 Sinamics Control Unit

Siemens 6SL3040-1MA00-0AA0 is the SINAMICS Control Unit CU320-2 DP for SINAMICS S120 drive systems, provided without a CompactFlash card and equipped with a PROFIBUS DP interface. As the CU320-2 DP control unit, it handles drive control and network communications over PROFIBUS DP, enabling integration with Siemens automation networks. The unit weighs approximately 2.3 kg and requires 80 mm of ventilation clearance above and below, per SINAMICS S120 control unit specifications. This exact configuration is used when a PROFIBUS DP-enabled CU320-2 is required without onboard memory media, forming a core component of SINAMICS S120 installations that rely on PROFIBUS for command and feedback signals.
