Product description

Siemens 6SN1118-0DJ21-0AA2 is a SIMODRIVE-611-D control module for a single digital drive axis. The unit is described as a Digital Control Loop Block High Performance and is designed for a Sin/Cos measuring system with 1 Vpp. Siemens 6SN1118-0DJ21-0AA2 therefore belongs in the control layer of a SIMODRIVE-611-D drive group alongside separate power modules, infeed modules and the existing CNC control architecture. For replacement, the 6SN1118 module group, single-axis configuration, High Performance control class and Sin/Cos-1-Vpp interface are the principal identifiers. The device is a plug-in control module for axis control within the 611-D system, not a 6SN1123 power section. Specialist product records identify the MLFB as Siemens SKU 6SN1118-0DJ21-0AA2 and describe its function as a Control Loop Block for digital drives. This assignment separates it from two-axis modules such as 6SN1118-0DH23 and from separate 6SN11 modules in the drive group. Siemens 6SN1118-0DJ21-0AA2 is relevant where one controlled axis with Sin/Cos feedback must remain within the installed SIMODRIVE architecture. The exact type number prevents the number of axes, feedback interface and performance class from being confused. Before replacement, compare the complete MLFB, encoder type, axis assignment and surrounding 611-D components with the machine documentation.

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.

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.
