The CU310-2 Control Unit features the following interfaces as standard:

• Fieldbus interface
  • CU310-2 PN:
    1 PROFINET interface with 2 ports (RJ45 sockets) with PROFIdrive V4 profile
  • CU310-2 DP:
    1 PROFIBUS interface with PROFIdrive V4 profile
• 1 DRIVE-CLiQ socket for communication with the DRIVE-CLiQ motor or other DRIVE-CLiQ nodes (e.g. Sensor Modules or Terminal Modules¹⁾)
• 1 encoder evaluation for evaluating the following encoder signals
  • Incremental encoder TTL/HTL
  • SSI encoder without incremental signals
• 1 PE (protective earth) connection
• 1 temperature sensor input (KTY84-130 or PTC)
• 3 parameterizable, fail-safe (can be used with firmware V4.5 and higher) digital inputs (isolated) or alternatively 6 parameterizable digital inputs (isolated).
  The fail-safe digital inputs can be routed, i.e. they can be routed via PROFIsafe to a higher-level controller.
• 5 parameterizable digital inputs (isolated)
• 1 parameterizable, fail-safe (can be used with firmware V4.5 and higher) digital output (isolated) or alternatively 1 digital output (isolated)
• 8 parameterizable bidirectional digital inputs/outputs (non-isolated)
• 1 analog input: ±10 V, resolution 12 bit + sign
• 1 Ethernet interface (socket RJ45) for commissioning and diagnostics
• 1 slot for the CompactFlash card on which firmware and parameters are stored
• 1 PM-IF interface for communication with the Power Modules in blocksize format
• 3 test sockets and one reference ground for commissioning support
• 1 interface for the BOP20 Basic Operator Panel²⁾

The status of the CU310-2 Control Unit is indicated via multi-color LEDs.

As the firmware and parameter settings are stored on a plug-in CompactFlash card, the Control Unit can be changed without the need for software tools.

¹⁾ Only for use with SINAMICS S120 drive solutions without SINUMERIK.

²⁾ BOP20 is not used on machine tools.
