4.1.4.1
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.
For double-axis controllers, the STO safety function has a two-channel structure that acts upon both axes.
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.
