Technical item or function
Functional safety Hardware based 'Safe Torque
Off' safety function to prevent
the drive from generating tor-
que on the motor shaft.
STO safety function has been de-
signed for use in accordance
with the following standards
SS1 safety function is realized in
compliance with type C of the
drives safety standard
EN61800-5-2 (Type C: "The
PDS(SR) initiates the motor de-
celeration and initiates the STO
function after an application-
specific time delay").
SS1 safety function has been de-
signed for use in accordance
with the following standards:
