Product description

Siemens 6SN1118-1NH01-0AA1 is a control module from the SIMODRIVE 611 universal HRS series for positioning tasks in modular drive systems. Siemens assigns this variant to the two-axis modules for encoders with sin/cos signals of 1 Vpp. Two independent drive controls support appropriate multi-axis configurations; according to the engineering manual, single-axis operation and use in single-axis power modules are also possible. The HRS generation requires firmware version 8.3 or later and therefore differs from older HR versions. These characteristics are essential for maintenance, retrofit, and spare-parts procurement because the 611 universal family includes variants for speed setpoint control, positioning, resolvers, and different numbers of axes. The suffix 1NH01-0AA1 identifies this positioning variant for sin/cos encoders. The module can optionally be expanded with a terminal module or suitable PROFIBUS DP modules; Siemens specifies SimoCom U together with the corresponding drive firmware and toolbox for parameterization and commissioning. Before replacement, the complete order number, axis configuration, encoder type, software version, installed option module, and machine parameterization should therefore be compared. The module is especially relevant for operators of older machine tools and automated production systems who want to retain an existing SIMODRIVE-611 configuration. Its clear assignment as an HRS positioning module helps exclude visually similar control inserts with different encoder or functional equipment and enables selection for the existing power module. For spare-part enquiries, the power-module version and installed fieldbus option are also important comparison points. This keeps the existing machine parameterization traceable and allows targeted procurement of the control insert for maintenance, repair, or planned recommissioning.

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.
