Safe฀stop฀1฀-฀SS1 4- Sicherheitsfunktion_SS1_Ueber
The฀safety฀function฀"safe฀stop฀1"฀(SS1)฀brakes฀the฀motor฀to฀standstill฀in฀
a฀controlled฀manner฀and฀removes฀the฀power฀to฀the฀motor.฀After฀a฀de-
fined฀period฀(STO฀delay฀time)฀or฀once฀the฀motor฀is฀at฀standstill,฀the฀safety฀
function฀"safe฀torque฀off"฀(STO)฀removes฀the฀power฀to฀the฀motor.฀
