TwinSAFE safe drive technology

AX8911 – TwinSAFE card for servo drives of the AX8xxx series

The AX8911 TwinSAFE drive option card is an optional extension of the Beckhoff AX8xxx servo drive series, in which it is permanently installed. The card enables you to define the safety functions by application. The type key of the servo drive determines whether it is a servo drive with STO (AX8xxx-x1xx) or Safe Motion (AX8xxx-x2xx). In the delivery state, a factory setting project with the safety function STO according to EN 61800-5-2 is integrated as an example. Further information can be found in the original operating instructions for the cards.

Axis modules with TwinSAFE Safe Motion

The axis modules are optionally available with integrated safety functions . These conform to IEC 61800-5-2 and fulfill the following safety standards:

• EN ISO 13849-1:2015, up to Cat 4, PL e
• EN 61508:2010, up to SIL 3
• EN 62061:2005 + A1:2013/A2:2015 up to SILCL3

Communication takes place via the FailSafe-over-EtherCAT protocol FSoE according to IEC 61784-3-12. When using the factory setting project, the safety function STO can be enabled either via two safe integrated digital inputs or FSoE.

Certification for third-party motors invalid The TÜV SÜD certificate applies to the list of approved components. Other components are not covered by the certificate. When using a third-party motor, you are responsible for the attachment and FMEA. Use Beckhoff AM8000 and AM8500 synchronous servomotors. Use Beckhoff servomotors AM8000 and AM8500 with the feedback system ordering information y = G...J.

Certification for third-party motor cables invalid The TÜV SÜD certificate applies to the list of approved components and cables. Other cables are not covered by the certificate. If you use a third-party motor cable, you are responsible for the installation and FMEA. Use original Beckhoff OCT motor cable.
