3.1 Characteristics
The following elements designate an NCU:
• Battery-backed real-time clock
• Slot for a CompactFlash Card (behind the blanking cover)
• DRIVE-CLiQ interfaces for connecting to the drive
• Interfaces for operation behind a hinged front cover:
– Ethernet ports
– PROFINET interfaces
– PROFIBUS interfaces
– Digital inputs/outputs (6 of which can be parameterized as inputs for probe and BERO)
• Commissioning interfaces:
– Ethernet interface
– Measuring sockets
3.2 Illustration
The following diagram shows an NCU 730.3B PN with its interfaces and control and display
elements (fault displays and status indicators). Please ensure that the structure of the NCUs is
virtually identical. There are only a few discrepancies, as follows:
• NCU 710.3B PN has 4 instead of 6 DRIVE-CLiQ interfaces.
NCU 7x0.3B PN
