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.
• 5 parameterizable digital inputs (floating)
• 1 digital output (isolated) or alternatively
  1 parameterizable, fail-safe digital output (isolated, can be used with firmware V4.5 or higher)
• 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 for KTY84‑130, Pt1000 or PTC (Pt1000 can be used from firmware V4.7 HF17)
• 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.
