  CU310-2 PN and CU310-2 DP Control Units

  The CU310‑2 Control Unit that is designed for the communication and open-loop/closed-loop control functions of a SINAMICS S120 (AC/AC) is combined with the PM240‑2 Power Module (can be used from firmware V4.8) to create a high-performance single-axis drive. A PROFINET (PN) variant and a PROFIBUS (DP) variant are available for fieldbus communication.

  CompactFlash card for CU310-2 Control Units

  

  The CompactFlash card contains the firmware and parameter settings. The CompactFlash card is plugged into the appropriate slot on the CU310-2 Control Unit.

  A CU310-2 Control Unit can perform the communication, open-loop and closed-loop control functions for one Power Module. The performance expansion is not required in this case.

  In addition to the firmware, the CompactFlash Card also contains licensing codes which are required to enable firmware options.

  In addition to the Article No., the following firmware options can currently be ordered:

  • Safety Integrated Extended Functions, order code F01
  • High output frequency ¹⁾, order code J01
  • DCB Extension, order code U01

  After the appropriate license has been purchased via the WEB License Manager available on the Internet, firmware options can also be subsequently enabled.

  Дизайн

  The CU310‑2 Control Unit has the following connections and 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 devices (e.g. Sensor Modules or Terminal Modules)
  • 1 encoder evaluation for evaluating the following encoder signals
    • Incremental encoder TTL/HTL
    • SSI encoder without incremental signals
  • 1 PE/protective conductor connection
  • 1 connection for the electronics power supply via the 24 V DC supply connector
  • 1 temperature sensor input for KTY84‑130, Pt1000 or PTC (Pt1000 can be used from firmware V4.7 HF17)
  • 3 parameterizable, fail-safe (can be used with firmware V4.5 and higher) digital inputs (floating) or alternatively 6 parameterizable digital inputs (floating).
    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 (floating)
  • 1 parameterizable, fail-safe (can be used with firmware V4.5 and higher) digital input (floating) or alternatively 1 digital output (floating)¹⁾
  • 8 parameterizable bidirectional digital inputs/outputs (non-floating) ¹⁾
  • 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 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 to the BOP20 Basic Operator Panel

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

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

  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⁾ A 24 V supply voltage must be connected to terminal X124 for the digital outputs to be used.

  Интеграция

  The CU310‑2 Control Unit drives Power Modules in blocksize format via the PM‑IF interface. DRIVE‑CLiQ motors or Sensor Modules (SMC) can also be connected to the integrated DRIVE‑CLiQ socket to permit the operation of motors without a DRIVE‑CLiQ interface.

  With the BOP20 Basic Operator Panel, parameters can be changed directly on the device. 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. The CU310‑2 Control Unit requires a CompactFlash card with firmware V4.4 or higher.

  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 with the STARTER commissioning tool and for accessing the integrated web server
  • 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. To operate the CU310‑2 Control Unit, a CompactFlash card with firmware V4.4 or higher is required.

  ¹⁾ The specified delay times refer to the hardware. The actual reaction time depends on the time slot 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.
