Short overview of "Safety functions  Safe stop" parameter group:
3.9.1.1 Priorisation
Stop functions with priority influence the process of already started subordinated functions.
1. Safe torque off (STO)
• The STO function has the highest priority and thus takes priority over all other functions.
Functions already started (e.g. SS1 or SS2) are cancelled and the drive is switched off.
2. Safe stop 1 (SS1)
• The SS1 function has priority over SS2. Taking the stopping time set for SS1 and SS2 and for
the SS1 mode (from SM301 V1.3) into consideration, the drive is switched to torque-free
operation.
3. Monitoring functions
• The monitoring functions have the same priorities. They can also be executed parallel to the
stop function.
