Product description
AX8911 11 Version: 1.2.0
NOTE
Digital inputs and Safety-over-EtherCAT (FSoE)
If you use the FSoE connection for accessing the AX8911 Drive Option and additionally the digital inputs of
the AX8000 on X15 or X25 during the commissioning of the axis, make sure that the wiring to the digital in-
puts is removed after the commissioning of the axis.
CAUTION
STO function
If the STO function described above is not suitable for the use case, it must be changed by the user or by
loading a user-defined safety project into the AX8911.
4.1.2 AX8911 with Safe Motion functions (AX8xxx-x2xx)
Through the integration of the AX8911 into the AX8000, the user can implement safety functions in
accordance with the following list:
• Stop functions such as STO, SOS, SS1, SS2
• Speed functions, such as SLS, SSM, SSR, SMS
• Acceleration functions, such as SAR, SMA
• Direction of rotation functions such as SDIp, SDIn
• Position functions such as SLP, SCA, SLI
• Braking functions SBC, SBT
Like the programming or configuration of the safety application, the entire parameterization of the AX8911
option card is performed from the TwinCAT software. All system-specific settings are stored together with the
application in the AX8911. The backup/restore mechanism familiar from the EL69x0 can be used for the
exchange of the AX8911. Further information on this can be found in the EL6910 user documentation (see
References [

8] ). Examples of the implementation of the safety functions can be found in the chapter Safe
Motion functions [
}
35] .
Through the use of a certified encoder (EDS35/EDM35), a Performance Level of PL d can typically be
attained with the example applications. This assumes that the safety applications in which these examples
are integrated are also implemented in such a way that a performance level PL d can be achieved.
4.2 Intended use
The AX8911 TwinSAFE drive option card extends the field of use of the Beckhoff AX8000 servo drive by
safety functions that allow it to also be used in the field of machine safety.
WARNING
Observe the intended use!
Use of the TwinSAFE drive option card other than for the intended purpose as described below is not per-
mitted!
The AX8911 card can be addressed as a TwinSAFE drive option card via the TwinSAFE inputs X15 or X25
or via an FSoE or TwinSAFE connection. Depending on which of these variants is used, the error reactions
of the TwinSAFE drive option card described below may be different.
