cu305 pn control unit
the cu305 control unit for the communication and open-loop/closed-loop control functions of a sinamics s110 is combined with the pm240‑2 power module in blocksize bbbbat (usable as of firmware v4.4 sp3) to create a powerful single drive.
the cu305 control unit features the following connections and interfaces as standard:
the cu305 control unit controls the pm240 2 power module in blocksize bbbbat (usable as of firmware v4.4 sp3) via the pm-if interface.
a bop20 basic operator panel can also be snapped directly onto the cu305 for diagnostic purposes.
drive-cliq motors can be connected to the integrated drive-cliq socket as well as sensor modules (smc) to permit the operation of motors without a drive-cliq interface.
the status of the cu305 is indicated via multi-color leds.
the cu305 can be operated optionally with memory card. the firmware and project data are stored on the memory card pluggable from below, so that the cu305 can be replaced without the support of software tools. this memory card can also be used to perbbbb standard commissioning on multiple drives of identical type. the card is available as an empty memory card or containing the latest drive firmware version. the card also contains the safety license for the extended safety functions. to use these extended safety functions, a memory card containing the safety license must be permanently inserted.
the cu305 and other connected components are commissioned and diagnosed with the starter commissioning tool.
connection example of cu305 control unit
1)the specified delay times refer to the hardware. the actual rebbbbbb time depends on the time slice in which the digital bbbbb or output is processed.
2) in order to use the digital outputs, an external 24 v power supply must be connected to terminal x124.
3) signal cables twisted in pairs and shielded.
