SINAMICS S110 Control Unit CU305 PN with PROFINET interface without memory card Control Unit SINAMICS Control Unit CU305 PN for the SINAMICS S110 servo converter. The Control Unit CU305 controls the Power Module PM340 via the PM-IF interface. For diagnostic purposes, for example, a Basic Operator Panel BOP20 can be snapped directly onto the CU305. Furthermore, an Intelligent Operator Panel (IOP) can be operated remotely on the RS232 interface for extensive diagnostic and commissioning functions. DRIVE-CLIQ motors or Sensor Modules SMC (Sensor Modules Cabinet-Mounted) can be connected to the integrated DRIVE-CLIQ socket in order to also operate motors without a DRIVE-CLIQ interface. The status of the CU305 is displayed via multi-colored LEDs and it can optionally be operated with a memory card. Commissioning and diagnostics of the CU305 and the connected components are carried out using the STARTER commissioning tool. A memory card is available for the CU305 control unit.
