3.1.5 Safety function STO
The safety function "Safe torque off" (STO) activates the pulse disabler on the servo ampli-
fier and removes the power to the motor. It meets the requirements in accordance with
EN61800-5-2.
The inputs STO1-ENABLE and STO2-ENABLE, when
} with single-channel activation without feedback, meet the requirements in accordance
with ENISO13849-1: PL d (Cat. 2) and EN/IEC 62061: SIL CL 2.
} With dual-channel activation with feedback, in accordance with ENISO13849-1: PL e
(Cat. 4) and EN/IEC 62061: SIL CL 3.
NOTICE
With dual-channel activation of the inputs STO1-ENABLE and STO2-EN-
ABLE, the safe pulse disabler must be tested periodically to ensure it
switches safely. See section 4.3.3, entitled "Safety function STO".
The safety card PMCprotegoS1 or PMCprotegoS2 can also be used to trigger the safety
function STO.
The STO1-ENABLE input on the servo amplifier has no function if the servo amplifier con-
tains a safety card. In this case, the safety card activates the safe pulse disabler on the
servo amplifier in order to shut down the power element.
