Product description

The Siemens 6SN1123-1AA00-0BA1 is a SIMODRIVE-611 power module in a 1 axis version with internal cooling. The original Siemens table 5-1 clearly assigns the type code 0BA within the 1 axis row to the 25-A transistor limit. This value is a semiconductor limit and must not be equated with the permissible rated motor current. For operation with asynchronous motors, Siemens states 8 A nominal current, 10 A current in the load cycle S6-40 % and 16 A peak current at 3.2 kHz pulse frequency. For synchronous motors, 9 A rated current and 18 A peak current apply at 4 kHz. The earlier 1FT5-specific specification of 12.5 A is not used in this exact 0BA table row and is therefore not continued. Siemens documents 600 V or 625 V DC as a supply for regulated feed; with unregulated feed-in, the intermediate circuit voltage results from the mains voltage multiplied by 1.35. The maximum output voltage is the intermediate circuit voltage divided by 1.4. Further exact table values are 1.8 A minimum motor current, 0.98 efficiency, 74 W total power loss in asynchronous operation and 90 W in synchronous operation. The internally cooled module weighs approximately 5.7 kg including packaging and uses a fan with a maximum of 19 m³/h free airflow. The motor connections are designed as plug connectors according to the same Siemens table. The Siemens module grid results in 50 mm width, 480 mm standard height and 288 mm depth with internal cooling. The information previously listed as “width 270 mm” is therefore incorrect; 270 mm is not the housing width of this module. Before replacing, the complete MLFB, number of axles, type of cooling, intermediate circuit, motor type, current load cycle and control module must be checked.

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.
