1.3 Appropriate use
The AX8000 multi-axis servo system is exclusively designed for the operation of suitable synchronous
motors with torque, speed and position control. The max. permissible effective voltage of the motors must be
higher than or at least equal to the effective mains voltage supplied to the servo system.
The supply, axis and capacitor modules of the AX8000 multi-axis servo system are installed exclusively as
components in electrical systems or machines. They may only be put into operation as integrated
components of the system.
WARNING
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 event of a fault in the drive sys-
tem.
The components and modules listed above may only be operated in a closed control cabinet, taking into
consideration the environmental and operating conditions [}27] described in the section: "Technical Data".
Improper use
The AX8000 multi-axis servo system 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.
1.3.1 Dual Use (EU1382/2014)
According to the EU directive 1382/2014 published on 30/12/2014, commercially available frequency
converters – that also means the Beckhoff product series: AX8000 multi-axis servo systems are now newly
classified as dual-use goods.
The goods list, Annex I of the Dual Use directive 428/2009 has been amended accordingly:
• Frequency converters (listed in goods list position 3A225) ≥ 600 Hz are subject to export control.
• Frequency converters (AX8000 multi-axis servo system) with a rotary field frequency of 599 Hz are not
subject to export control.
The multi-axis servo system AX8000 is only available with a rotating field frequency of max. 599 Hz
delivered. This is sufficient for commissioning all synchronous servomotors of the Series AM8x00 with full
performance.

2.2 Electromagnetic compatibility (EMC)
Beckhoff Automation GmbH & Co. KG guarantees the conformity of the AX8000 multi-axis servo system to
the EMC Directive 2014/30/EU.
Applied harmonized standards:
• IEC / EN 61800-5-3
Installation of electrical systems and components
In order to be able to establish an effective protective earth conductor system, in addition to the protective
conductors and all electronic components all conductive components of a machine must be included in the
protective earth conductor system through equipotential bonding.
CAUTION
Attachment of the protective earth conductor!
When installing electrical systems and components, the protective earth conductors should
always be connected first and removed last. The specifications for the protective earth con-
ductor connections depend on the level of leakage currents:
• The minimum requirement for the protective earth conductor is a KU value1) of 4.5
• The minimum requirement for leakage currents is IL < 10mA or KU = 6 for IL > 10mA.
1) The KU value is a variable for the classification of safety-related types of failure for protection against
dangerous shock current and excessive heating. A value of KU = 4.5 in relation to interruption is attained:
• with a permanently attached protective earth conductor ≥ 1.5 mm²
• for protective earth conductor connections ≥ 2.5 mm² with connectors for industrial systems (IEC
60309-2).
KU = 6 in relation to interruption is attained with permanently connected conductors ≥ 10 mm², wherein the
type of connection and routing must comply with the standards applicable to PE conductors.

2.3.1 UL-specific chapter
The integrated protection against short circuit is no substitute for the external mains protection. The mains
protection must comply with the manufacturer's specification and the national and international regulations
and laws.
Components of the AX8000 multi-axis servo system must be operated on mains supplies that can supply a
maximum current carrying capacity of 5 kA at 480 VAC.
UL circuit breakers of class "J" are to be used for protection.
• AX8620 power supply modules must be fuse-protected with 30A max.
• AX8640 power supply modules must be fuse-protected with 60A max.
With regard to alternatives to the UL circuit breakers of the class "J", be sure to refer to the UL standard "UL
508 A, chapter SB4.2.3, exception no. 1".
Fuse holders with UL approval
Possible configuration examples are described in the further course of this document. Be-
fore implementing a UL configuration, please contact your UL certification body and discuss
further necessary boundary conditions. Furthermore, when using fuse holders, care must
be taken that they have also been tested and manufactured in accordance with the applica-
ble standards of the UL certification body.

Guidelines and Standards
Multi axis servo system AX800012 Version: 1.6
2.3.1.1 UL configuration example of a system group
System group with UL approval:
The following figure describes a possible configuration example, a system group consisting
of several AX8000 devices with UL approval. Please note that prior to implementation on
your machine or system, it is essential to consult your responsible UL certification authority,
to discuss all further and required boundary conditions. Furthermore, when using fuse hold-
ers, it is important to ensure that they comply with the current directives and standards of
the UL certification body and that they have been tested accordingly.
To configure the current-limiting circuit breakers for your system group, proceed as
follows:
Determine the total rated output currents of all AX8000 modules in the system group.
In our example, we use an AX8640-0000 power supply module, an AX8810-0000 capacitor module, an
AX8118-0000 axis module and an AX8108-0000 axis module.
Calculation:
Rated output current of the AX8118-0000 (18 A) and AX8108-0000 (8 A) axis modules = 26 A.
Total rated output current = 26 A x correction factor 1.1 = 28.6 A.
According to the calculation, the system group would have to be fuse-protected with 28.6 A.
Please select the next larger default rating according to UL508A, Table SB4.2 for the sizing of your fuse
protection.
Selection of current-limiting circuit breakers according to UL508A, Table SB4.2:
In our configuration example, we select a UL circuit breaker according to UL508A, Table SB4.2 of type "G"
with 40 A, based on the total rated output current.
