Product description

Siemens 6SL3040-1MA01-0AA0 is the CU320-2 PN control unit for modular SINAMICS-S120 drive systems. It takes on central control, communication and coordination tasks within the drive network. The exact Siemens table specifies an electronics supply of 24 V DC with a permissible range of 20.4 to 28.8 V. Without load on the DRIVE-CLiQ and digital outputs, the current consumption is a maximum of 1.0 A. The maximum power loss is 24 W. A maximum of 5.5 A is permitted for all supplied outputs together. The CU320-2 PN has four DRIVE-CLiQ ports; Siemens states up to 100 m cable length per DRIVE-CLiQ connection. Two PROFINET ports with 10/100 Mbit/s and a separate LAN port are available for system communication. The signal level includes twelve isolated digital inputs and eight non-isolated, parameterizable digital inputs/outputs. There is also an RS232 interface, an option slot and three measuring connections T0 to T2. This allows the control unit to coordinate several drive components via DRIVE-CLiQ and at the same time connect the higher-level controller via PROFINET. 80 mm of free space above and below is provided for sufficient ventilation. The current Siemens environmental product declaration states a device weight of 2.3 kg for the exact reference product. The PN communication variant can be distinguished from other CU320-2 versions by its PROFINET equipment. Before replacement, the complete MLFB, CompactFlash card and project status, DRIVE-CLiQ topology, PROFINET device name, IP address, telegram configuration, option board, terminal assignment, 24-V supply and the released firmware must be checked together. The assignment of the connected Motor Modules, encoders and Terminal Modules must also be retained in the project. An empty replacement module does not automatically take over this configuration. The CU320-2 PN may therefore not be exchanged for other communication or hardware variants based solely on the CU320 designation.

FAQ

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged. If a fault occurs within 14 calendar days, please contact us in writing. Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
