    Integrated safety technology Safety subfunctions Safety subfunctions The following drive-related safety functions can be used: • STO (Safe Torque Off according to EN 61800-5-2) by disconnecting the STO in- put. If the STO function is activated, the frequency inverter no longer supplies power to the motor for generating torque.

  • Page 11: Restrictions

    Integrated safety technology Restrictions Restrictions • Note that if the drive does not have a mechanical brake, or if the brake is defec- tive, the drive may coast to a halt (depending on the friction and mass moment of inertia of the system). In case of regenerative loads, the drive can even accelerate. This must be taken into account in a risk assessment of the system/machine.

  • Page 17: Requirements On Startup

    Safety requirements Requirements on startup – SEW‑EURODRIVE recommends to switch off the 24  V voltage supply at two poles. • The values specified for the safety controller must be strictly adhered to when designing the circuit. • The switching capacity of the safety relays or the relay outputs of the safety con- troller must correspond at least to the maximally permitted, limited output current of the 24 V supply voltage.

  • Page 18: Connection Variants

    Connection variants General information Connection variants General information Generally, all the connection variants listed in this documentation are permitted for safety-relevant applications as long as the basic safety concept is met. This means that you must always make sure that the DC 24 V safety inputs are operated by an ex- ternal safety relay or safety controller, thereby preventing an automatic restart.
