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.
Caution – Risk of injury!
Basically, electronic devices are not fail-safe. The machine manufacturer is responsible for
ensuring that the connected motors and the machine are brought into a safe state in the
WARNING
event of a fault in the drive system.
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.
Improper use
The external brake resistor AX2090-BW5x-xxxx is not suitable for use in the following areas:
• in ATEX zones without a suitable housing
• in areas with aggressive environments (e.g. aggressive gases or chemicals)
The relevant standards and directives for EMC interference emissions must be complied with in residential
areas. The servo drives may only be installed in housings and control cabinets with appropriate shielding
attenuation.
