Siemens Sinamics CU320 Modules: Beyond the User Manual

There are two Sinamics S120 CU320 Modules. There is the CU320-2 DP, which is the 6SL3040-1MA00-0AA0, and the CU320-2 PN, which is the 6SL3040-1MA01-0AA0.

These multi-drive Control Units increase axis count and functionality. They have an Ethernet port, as well as more I/O and controller to controller communication. Each unit can manage up to 6 servo or vector axes in a high performance system. For standard systems, up to 12 V/Hz axes can be controlled from one CU320-2 unit. These Control Units significantly reduce system costs, as they increase functionality for positioning, safety integration, and drive control allowing all these functions to be controlled by one unit versus several. There is also additional flexibility with a high number of programming options and digital inputs. With up to 12 binary inputs, the modules’ high I/O count add ease of use. The additional Ethernet port expands programming options as well. Overall, the CU320-2 control units allow for simple yet flexible performance with minimal cost and space requirements.

CU320-2 DP

CU320-2 DPThe CU320-2 DP is a Sinamics Control Unit with a Profibus interface. It is a central Control Module in which the closed-loop and open-loop functions are implemented for one or more Line Modules and/or Motor Modules. It can be used with firmware version 4.3 or greater. It has 12 digital inputs, 8 digital inputs/outputs, 4 DRIVE-CLiQ interfaces, a Profibus and Ethernet interface, a serial interface (RS232), an option slot, and 3 measuring sockets.

MRO Electric stocks new and refurbished CU320-2 DP Control Units, which is part number 6SL3040-1MA00-0AA0. If you would like a replacement module, please call 800-691-8511 or email sales@mroelectric.com.

Siemens 6SL3040-1MA00-0AA0: Beyond the User Manual

The Siemens 6SL3040-1MA00-0AA0 is a Sinamics S120 central control module in which the closed-loop and open-loop functions are implemented for one or more Line Modules and/or Motor Modules. The module features 12 digital inputs, 8 digital inputs/outputs, 4 DRIVE-CLiQ interfaces, 1 PROFIBUS interface, 1 LAN (Ethernet) interface, 1 RS232 serial interface, an option slot, and 3 measuring sockets.

The 6SL3040-1MA00-0AA0 features integrated lateral holders, which allow it to be installed directly on a Line Module in book size format or on a power unit in chassis format. The holders required to do this are supplied together with the Line Modules and the power units in the chassis format.

It is important to note that CompactFlash cards with firmware version 4.3 can only run a 6SL3040-1MA00-0AA0 / CU320-2 DP.  The card may only be removed and inserted when the module is in a voltage free state. Performing this during operation could result in a loss of data and potentially a plant standstill. If you are replacing your Control Unit, remove the CompactFlash card and keep it for insertion into the replacement unit. This is important to prevent the loss of data on the card.

An open input is interpreted by the CU320-2 DP as “low.” To enable the digital inputs function, terminal M1 must be connected. This is achieved by providing the ground reference of the digital inputs or a jumper to terminal M.

The 6SL3040-1MA00-0AA0 uses a 24V DC power supply voltage. It has a 1A DC current without the DRIVE-CLiQ or digital outputs. The module’s power loss is 24W, and the maximum DRIVE-CLiQ cable length is 100 meters. The unit weights precisely 2.3 kg.
