Foreword

Liability conditions

The responsible staff must ensure that the application or use of the products described satisfy all the requirements for safety, including all the
relevant laws, regulations and guidelines.

The documentation has been prepared with care. The products described are, however, constantly under development. For this reason, the
documentation may not always be have been fully checked for consistency with the performance data, standards or other characteristics described.
None of the statements in this manual represent a guarantee for as set out in § 443 of the German Civil Code or a statement about the assumed
use according to the contract as set out in § 434 para. 1 clause 1 no. 1 of the German Civil Code. In the event that it contains technical or editorial
errors, we retain the right to make alterations at any time and without warning. No claims for the modification of products that have already been

Copyright

© These instructions are protected by copyright. Any reproduction or third party use of this publication, whether in whole or in part, without the
written permission of Beckhoff Automation GmbH, is forbidden.

Appropriate use

The brake resistors from the AX2090-BW5x-xxxx series are exclusively designed for direct application with an AX5000 series servo drive or the
AX5021 brake module. They are designed for installation as components in electrical installations and machines together with the servo drive or the
brake module, and this is their only purpose.

Scope of supply

The scope of supply includes the following components:

Brake resistor from the required performance class, technical documentation and packaging

If one of the components is damaged please notify the logistics company and Beckhoff Automation GmbH immediately.

Security

Safety rules

The responsible staff must ensure that the application or use of the products described satisfy all the requirements for safety, including all the
relevant laws, regulations and guidelines.

Caution – Danger of death!

Even when the AX5000 is disconnected from the mains voltage, dangerous voltage continues to be present at the "X02" terminals

DANGER

WARNING

Exclusion of liability

All the components are supplied in particular hardware and software configurations appropriate for the application. Modifications to hardware or
software configurations other than those described in the documentation are not permitted, and nullify the liability of Beckhoff Automation GmbH.

Personnel qualification

This description is only intended for trained specialists in control, automation and drive engineering who are familiar with the applicable national
standards. Knowledge of machine safety legislation is compulsory.

Product description

Warning

The external brake resistors of the AX2090-BW5x-xxxx series are able to convert the dynamic energy generated during braking of a servomotor into
heat. The series covers a wide continuous power and peak power range. The built-in temperature switch enables the system to respond
immediately to any overload of the brake resistor through analysis in the AX5000 or the PLC. All brake resistors of the AX2090-BW5x-xxxx series
are UL and CSA approved.

of the DC link for at least 5 minutes. Never touch the terminals within this period.

Caution - Risk of injury through hot surfaces!

The temperature of the brake resistor housing surface may reach over 200 °C. Please ensure that the housing has cooled down
below 40 °C before touching it.

Caution - Destruction of the equipment

The brake resistor may only be connected to individual AX5000 devices or AX5021 brake modules. It must never be used in a drive
system without the AX5021 brake module, since this may lead to its destruction through overload.

Caution - Destruction of the brake resistor and consequential damage

The built-in temperature switch must be monitored, so that the machine can be stopped in a controlled manner and switched off in
the event of an overloading of the brake resistor.
