Product description

The Bosch Rexroth DKR02.1-W300B-BE12-01-FW is a compact Indramat drive controller from the DKR02 series for high-performance machine axes. This exact variant is designed for ADF and 2AD main spindle motors, 1MB frameless spindle motors, and LAF and LSF linear motors. It uses SERCOS as its command interface and supports digital servo and resolver signals for motor feedback. The type code specifies an integrated bleeder, air cooling with a built-in blower and function code 12. Its nominal current class is approximately 300 A. The documented operating current is 141 A at 4 kHz and 110 A at 8 kHz. Continuous regenerated power is approximately 43 kW. The controller has protection class IP20 according to IEC 529 and EN 60529. Operation is documented at ambient temperatures up to 55 °C and installation altitudes up to 1,000 m; the storage and transport range is -30 to 80 °C. Mains and motor connections are located at the top of the unit. X8 is assigned to the signal-voltage connection, while X9 carries input/output control signals. The offered unit is associated with firmware FWA-DIAX03-SHS-02VRS-MS in the source listing. Before replacement, the complete order number DKR02.1-W300B-BE12-01-FW, SERCOS interface, feedback type, function code, current class and firmware must match the machine configuration exactly. Motor type, terminal assignment, cooling path, regeneration concept and existing parameter data must also be checked. This used controller is particularly suitable as a like-for-like replacement in existing DIAX03 systems where motor, control system and axis parameters are to remain unchanged. Saved parameter data should be fully available before replacing the controller. Neighboring DKR02 variants must not be substituted without verification because interface and function codes can differ.

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.
