CU310 DP Control Unit производства Siemens

The CU310 DP Control Unit provides the communications and open-loop/closed-loop control functions for a Power Module. The CU310 DP combined with a Power Module and CompactFlash Card creates a powerful single-axis AC drive with a PROFIBUS interface to a higher-level control.

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.

CU310 DP Control Unit features the following interfaces as standard:

1 DRIVE-CLiQ socket for communication with other DRIVE-CLiQ devices, e.g. Sensor or Terminal Modules
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 V4 profile
1 encoder evaluation
The following encoder signals can be evaluated:
- Incremental encoder TTL/HTL
- SSI encoder without incremental signals
4 parameterizable digital inputs (floating)
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 electronic power supply via the 24 V DC power supply connector
1 PE/ground conductor connection
1 safe standstill input (enable pulses) for controlling the connected PM340 Power Module
1 temperature sensor input (KTY84‑130 or PTC)

The status of the CU310 DP Control Unit is indicated via multi-color LEDs.

A BOP20 Basic Operator Panel can also be snapped directly onto the CU310 DP Control Unit 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.

The CU310 DP Control Unit drives Power Modules in blocksize format via the PM‑IF interface. In this case, other DRIVE-CLiQ components such as Sensor or Terminal Modules, can be connected to the DRIVE-CLiQ socket on the CU310 DP Control Unit.

Power Modules in chassis format are driven by the CU310 DP Control Unit via the DRIVE-CLiQ interface. With this option, Sensor and Terminal Modules must be connected to the free DRIVE-CLiQ sockets on the chassis 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. The CU310 DP Control Unit requires a CompactFlash Card with firmware version 2.4 or higher.

A CU310 DP Control Unit communicates with the higher-level control system using PROFIBUS and the PROFIdrive V4 profile.

An external 24 V power supply can be connected to the CU310 DP Control Unit when the power connection for the Power Module is not energized.
