  CU310-2 PN and CU310-2 DP Control Units

  The CU310‑2 Control Unit for the communication and open-loop/closed-loop control functions of a Power Module is combined with the Power Module to create a powerful single drive. A PROFINET (PN) variant and a PROFIBUS (DP) variant are available for fieldbus communication.

  Дизайн

  CU310‑2 Control Units feature 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 to allow communication with other DRIVE‑CLiQ nodes
  • 1 encoder evaluation for evaluating the following encoder signals
    • Incremental encoder TTL/HTL
    • SSI encoders without incremental signals
  • 6 parameterizable digital inputs (isolated) or alternatively
    3 parameterizable, fail-safe digital inputs (isolated, can be used with firmware V4.5 and higher).
    The fail-safe digital inputs can be routed, i.e. they can be routed via PROFIsafe to a higher-level controller.
  • 1 digital output (isolated) or alternatively
    1 parameterizable, fail-safe digital output (isolated, can be used with firmware V4.5 or higher)
  • 5 parameterizable digital inputs (floating)
  • 8 parameterizable bidirectional digital inputs/digital outputs (non-floating)
  • 1 analog input, either ± 10 V (resolution 12 bits + sign) or ± 20 mA (11 bits + sign)
  • 1 Ethernet interface (RJ45 socket) for commissioning and diagnostics
  • 1 serial RS232 interface
  • 1 connection for the electronics power supply via the 24 V DC supply connector
  • 1 temperature sensor input (KTY84‑130 or PTC)
  • 3 measuring sockets and one reference ground for commissioning support
  • 1 slot for the CompactFlash card on which firmware and parameters are stored
  • 1 PM-IF interface for communication with Power Modules in blocksize format
  • 1 interface to the BOP20 Basic Operator Panel
  • 1 PE connection

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

  A BOP20 Basic Operator Panel can also be snapped directly onto the CU310‑2 Control Unit for diagnostic procedures.

  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.

  Интеграция

  Power Modules in chassis format are controlled from the CU310-2 Control Unit via the DRIVE-CLiQ interface. Sensor Modules and Terminal Modules must be connected to the free DRIVE‑CLiQ sockets of the Power Module.

  Parameter settings can be changed directly via the BOP20 Basic Operator Panel. The BOP20 Basic Operator Panel can also be snapped onto the CU310‑2 Control Unit during operation to perform diagnostics.

  The CU310‑2 Control Unit and other connected components are commissioned and diagnosed with the STARTER commissioning tool.

  A CU310-2 DP Control Unit communicates with the higher-level control system using PROFIBUS and the PROFIdrive V4 profile.

  A CU310‑2 PN Control Unit communicates with the higher-level control system using PROFINET IO and the PROFIdrive V4 profile.

  The SINAMICS S120 drive system with the CU310‑2 PN Control Unit then assumes the function of a PROFINET IO device and can perform the following functions:

  • PROFINET IO device
  • 100 Mbit/s full duplex
  • Supports real-time classes of PROFINET IO:
    • RT (Real-Time)
    • IRT (Isochronous Real-Time), minimum send cycle 500 μs
  • Connects to controls as PROFINET IO devices using PROFIdrive compliant with Specification V4
  • Standard TCP/IP communication for engineering processes using the STARTER commissioning tool
  • Integrated 2-port switch with two RJ45 sockets based on the ERTEC ASIC. The optimum topology (line, star, tree) can therefore be configured without additional external switches.

  A 24 V supply voltage must be connected to terminal X124 for the digital outputs to be used. The CU310-2 DP Control Unit requires a CompactFlash card with firmware V4.5 or higher.

  ¹⁾ The specified delay times refer to the hardware. The actual reaction time depends on the time slice in which the digital input 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.
