CU310 DP Control Unit Siemens

Обзор



The CU310 DP Control Unit for the communication and openloop/closed-loop control functions of a Power Module is combined with the Power Module to create a powerful single drive.

Дизайн



The CU310 DP Control Unit has the following interfaces as standard:

  • 1 DRIVE-CLiQ socket to allow communication with other DRIVE-CLiQ nodes
  • 1 PM-IF interface for communication with Power Modules in blocksize format
  • 1 interface to the BOP20 Basic Operator Panel
  • 1 PROFIBUS interface with PROFIdrive profile
  • 1 encoder evaluation
    The following encoder signals can be evaluated:
    • Incremental encoder TTL/HTL
    • SSI encoder without incremental signals
  • 4 parameterizable digital inputs (isolated)
  • 4 parameterizable bidirectional digital inputs/digital outputs (non-floating)
  • 1 serial RS232 interface
  • 1 slot for the CompactFlash card on which firmware and parameters are stored
  • 3 test sockets and one reference ground for commissioning support
  • 1 connection for the electronics power supply via the 24 V DC supply connector
  • 1 PE/protective conductor connection
  • 1 connection for Safety Integrated
  • 1 temperature sensor input (KTY84-130 or PTC)

The status of the CU310 DP Control Unit is indicated via multicolor LEDs.

A BOP20 Basic Operator Panel can be snapped directly onto the CU310 DP Control Unit, e.g. for diagnostic purposes.

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, chassis format are controlled from the CU310 DP 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 with the BOP20 Basic Operator Panel. The BOP20 panel can also be snapped onto the CU310 DP Control Unit during operation to perform troubleshooting procedures.

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

A CU310 DP Control Unit communicates with the higher-level control system using PROFIBUS according to the PROFIdrive profile.

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.
