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.
