Emergency Stop via SS1 and handling OFF3
The SINAMICS safety function Safe Stop 1 (SS1) is ideal for an Emergency Stop function.
SS1 provides braking along the OFF3 ramp with subsequent pulse suppression, i.e. STOP
category 1 according to IEC 61800-5-2.
If an Emergency Stop is performed via SS1, Emergency Stop via OFF3 can be omitted;
parameter p0849[0] = 1 BICO. In this case, it will be necessary to change the on/off
sequence.
