Lenze i750 - Safe Stop Emergency (SSE)

Safe stop emergency (SSE)
The safety funcon SSE has the highes
t priority. The safety funcon SSE is controlled primarily
from all states, operang modes or safety funcons. Depending on the parameter seng in
0x28A3:001, SSE acvates one of these funcons:
4Safe torque o (STO)
4Sa
fe stop 1 (SS1)
Connect the emergency stop buon, which mus
t not be overridden by the safe
repair mode (RMS), to the SSE funcon via the safety controller and the safety
bus.
Funconal descripon
The SSE safety funcon iniates the parameterized stop funcon with the highest priority.

Excepon
If a parameterized trigger source for SSE can be deacv
ated by the "Safe Mung" funcon,
SSE is not eecve during "Safe Mung".
