Basic Safety - STO
DANGER!
With the "Safe torque o" (STO) funcon, no “emergency‑stop" can be executed according to EN 60204−1
without addional measures. There is no electrical isolaon between the motor and inverter and no service
switch or maintenance switch!
Possible consequences: Death or severe injuries
▶
"Emergency stop" requires electrical isolaon, e. g. via a central mains contactor.
