19.2 Safe Emergency Stop (SSE)
The SSE safety funcon has the highest priority. The SSE safety funcon is primarily triggered
fr
om all states, operang modes or safety funcons. Depending on the parameter seng in
0x28A3:0010x28A3:001, the emergency stop funcon acvates one of the funcons:
4Safe Torque O (STO)
4Sa
fe Stop 1 (SS1)
NOTICE
Emergency stop buons must not be overruled by a special operaon.
Otherwise the
funconal safety of the system cannot be guaranteed anymore.

Precondions
The emergency stop buons are connected to the emergency stop funcon.
Details
The
funcon is acvated by the following:
•
a da
ta telegram with a corresponding content is sent to the inverter via the safety bus.
•
"OFF state" at a safe input which has been assigned to the funcon by parameterisaon.
Via a safe input, if the corresponding parameter is assigned to the safe input.
Acvaon of the
funcon
A data telegram is sent to the inverter via the safety bus. See chapter "Safe network interfa-
ces". ^ 439
