Foreword

Disclaimer

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

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.

The documentation has been prepared with care. The products described are, however, constantly under development. For that reason the documentation is not in every case checked for consistency with performance data, standards or other characteristics. 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 supplied may be made on the basis of the data, diagrams and descriptions in this documentation.

Appropriate use

The AX5021 brake module is intended exclusively for direct use in a drive system with servo drives from the AX5000 series. The brake modules are installed together with the servo drives as components in electrical systems and machinery and may only be used in this way.

Scope of supply

The scope of supply includes the following components:

brake module, technical documentation and packaging

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

Safety

Safety regulations

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!

Due to the DC link capacitors dangerous voltage may persist at the DC link contacts "X02" after the servo drive has been disconnected from the mains supply. After disconnecting the servo drive wait 5 minutes and measure the voltage at the DC link

DANGER

WARNING

contacts DC+ and DC-. The device is safe once the voltage has fallen below 50 V.

Caution - Risk of injury through hot surfaces!

The surface of the brake module housing can become very hot. Please ensure that the housing has cooled down below 40 °C before touching it.

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

Using a brake module it is possible to take up additional braking power in a drive system, because the connection of an external brake resistor without a brake module in a drive system with devices up to max. 25 A rated current is not permissible. A further advantage is the simple installation and the small space requirement of the brake module. The brake module is equipped with a complete DC link and an internal brake resistor and enables the connection of an external brake resistor with the integrated brake chopper. Several brake modules can be integrated into a drive system.

Operating conditions!

The brake module may only be used together with servo drives of the AX51xx-xxxx-02xx or AX52xx-xxxx-02xx series. These
