You can find information about the available accessories in the following chapters.
5.1.6.1 Safety technology
The safety modules are used to realize the STO safety function. They prevent the generation of
a rotating magnetic field in the power unit of the drive controller. For an external requirement or
in the event of error, the safety module switches the drive controller to the STO state. Different
user interfaces and additional safety functions are available depending on the selected design
of the accessories.
Information
Note that the drive controller is delivered as a standard version without safety technology (SZ6
option). If you want a drive controller with integrated safety technology, you must order it
together with the drive controller. The safety modules are an integrated part of the drive
controllers and must not be modified.
