Product description

Siemens 1FT6102-8AF71-4AH0 is a permanent-magnet synchronous servo motor from the SIMOTICS S 1FT6 family. It is intended for precise, dynamic machine axes where the complete motor code determines electrical, mechanical and feedback compatibility. This variant is documented with a standstill torque of 27 Nm at a winding temperature rise of 100 K and a rated speed of 3000 min⁻¹. Heat is dissipated by natural cooling, so the mounting surface, ambient temperature and free convection in the machine area must be considered. Feedback is provided by a sin/cos incremental encoder with 1 Vpp and 2048 signal periods per revolution. This I-2048 version must match the installed drive controller, feedback cable and parameter settings. The motor includes a holding brake that must be incorporated into the existing safety and load concept for vertical axes and standstill conditions. Power and signal connectors exit axially on the drive end. The motor uses IM B5 mounting and, according to the product data, can also be installed in positions IM V1 and IM V3. Its plain shaft has runout tolerance N; vibration severity grade N and a labyrinth seal with IP64 protection complete the variant specification. Replacement planning should compare 1FT6102-8AF71-4AH0, the 27-Nm class, 3000-min-1 winding, I-2048 encoder, holding brake, shaft design, connector outlet and mounting position together. Coupling, flange fit, brake control, motor cable, encoder cable and inverter data must also be checked against the installed axis before fitting. Protection rating, runout and vibration grade are relevant to a mechanically safe replacement. An exact variant comparison prevents installation of a similar-looking 1FT6102 motor with a different encoder, brake or connector orientation.

FAQ

Frequently asked questions

Contact us
Which feedback system does Siemens 1FT6102-8AF71-4AH0 use?

This variant uses a sin/cos incremental encoder with 1 Vpp and 2048 signal periods per revolution. The I-2048 feedback must match the installed controller and encoder cable.

What must be checked for mechanical replacement?

Check the IM-B5 flange, plain shaft, axial connector outlet, holding brake, labyrinth seal, coupling and mounting position. A similar-looking 1FT6102 can have different variant features.

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.
