Parameterization
WARNING
Check the parameterization of the TwinSAFE drive option card!
The TwinSAFE drive option card determines errors in the parameterization, but no logical testing of the pa-
rameters or the loaded safety program can take place. Hence, you must ensure by means of an accep-
tance test that the parameterization and the safety program are correct for the application. This test must
be performed by the machine manufacturer.
The combination of AX8000 and AX8911 may be used in production only when this test has produced a
positive result for all safety-relevant functions.
WARNING
Avoid incorrect parameterization of the servo drive!
Incorrect parameterization of the servo drive (e.g. current controller oscillates or is too lethargic) can lead to
switch-off. The AX8911 switches the motors of the AX8000 servo drive torque-free. Any motors that are still
moving coast to a halt. With suspended or pulling loads the motors may also accelerate. External safety
measures (e.g. mechanical service brakes) are to be provided by the user to avoid unwanted movements.
WARNING
Avoid incorrect dimensioning of the servo drive!
Loads that cannot be braked by the AX8000 servo drive (e.g. if the AX8000 servo drive is under-dimen-
sioned) can lead to switch-off. The AX8911 switches the motors of the AX8000 servo drive torque-free. Any
motors that are still moving coast to a halt. With suspended or pulling loads the motors may also acceler-
ate. External safety measures (e.g. mechanical service brakes) are to be provided by the user to avoid un-
wanted movements.
External safety measures
WARNING
Provide for external safety measures for the STO function of the TwinSAFE drive option
card!
If the STO safety function is executed, the connected motors are not braked, but are switched torque-free.
This leads to the motors coasting to a halt. The duration of this coasting depends on how much kinetic en-
ergy is present in the system. With suspended or pulling loads the motors may also accelerate. The user
must provide appropriate external safety measures (e.g. mechanical service brakes) to prevent this.
WARNING
Provide for external safety measures for the error reactions of the TwinSAFE drive option
card!
The STO error reaction is executed if the TwinSAFE drive option card determines an error.
If the STO error reaction is executed, the connected motors are not braked, but are directly switched
torque-free. This leads to the motors coasting to a halt. The duration of this coasting depends on how much
kinetic energy is present in the system. With suspended or pulling loads the motors may also accelerate.
The user must provide appropriate external safety measures (e.g. mechanical service brakes) to prevent
this.
