Product description

The Siemens 6SE7022-6TC21 is a compact inverter from the SIMOVERT MASTERDRIVES Vector Control series. Within the modular 6SE70 drive system, it converts the DC-link voltage into a controlled three-phase output voltage for industrial three-phase motors. This exact version is specified for a DC-link voltage range of 510 to 620 V DC. Rated current is 25.5 A and the assigned drive power is 11 kW. The enclosure provides IP20 protection and is designed as a compact built-in unit for a protected control cabinet. The MASTERDRIVES-VC platform uses fully digital control and IGBT inverter technology. It supports encoder-based vector control for dynamic applications requiring high torque accuracy, as well as sensorless vector control and V/f operation for simpler drive tasks. Device dimensions are stated as 61 × 36 × 18 cm. Before replacement, the complete order number, DC-link voltage, rated current, power class and installed Control Unit must match. Option modules, parameters, motor data, encoder connection, communication interface and terminal assignment must also be documented from the existing system. Because the 6SE70 family includes different control and power versions, the 6SE7022-6TC21 must not be exchanged for a neighboring variant solely on the basis of similar enclosure dimensions. For commissioning, backed-up parameters should first be checked offline and then transferred to the replacement hardware in a controlled process. Rotation direction, current limits, ramps, encoder feedback, fieldbus communication and protective functions should subsequently be checked step by step with the machine stopped and under defined load. This item is intended for targeted maintenance of machines that use exactly this SIMOVERT-VC power section.

FAQ

Frequently asked questions

Contact us
What performance data apply to the Siemens 6SE7022-6TC21?

The inverter is specified for a DC-link voltage of 510–620 V DC, a rated current of 25.5 A and 11 kW drive power.

Which control modes does the SIMOVERT-VC platform support?

The platform supports vector control with encoder, sensorless vector control and V/f control; the specific parameter set must be transferred from the existing system.

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.
