FR9–FR11: 76
Functional safety
Hardware based ‘Safe Torque
Off’ safety function to prevent
the drive from generating torque
on the motor shaft.
STO safety function has been de-
signed for use in accordance
with the following standards
EN 61800-5-2 Safe Torque Off (STO) SIL3
EN ISO 13849-1 PL “e” Category 3
EN 62061 SILCL3
IEC 61508 SIL3
The function also corresponds to an uncontrolled stop in accord-
ance with stop category 0, EN 60204-1.
EN 954-1, Category 3
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:
EN 61800-5-2 Safe Stop 1 (SS1) SIL3
EN ISO 13849-1 PL "e" Category 3
EN 62061 SILCL3
IEC 61508 SIL3
The function also corresponds to a controlled stop in accordance
with stop category 1, EN60204-1.
