The CU310-2 Control Unit features 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 power supply connector
• 1 temperature sensor input (KTY84?130 or PTC)
• 3 parameterizable, fail-safe (can be used with firmware version 4.5 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 version 4.5 and higher) digital output (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 bit + sign) or ±20 mA (11 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 to the BOP20 Basic Operator Panel

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 purposes, for example.

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⁾ In order to use the digital outputs, a 24 V supply voltage must be connected to terminal X124.
