Siemens SINAMICS G220 - Responses to Safety Messages; Stop Responses; Priority of Stop Responses and Stop Functions

14.12.11 Responses to safety messages
14.12.11.1 Stop responses
Description of function
The converter triggers a fault reaction in response to certain events:
• Stop response SCF
The converter detects a discrepancy in the Safety Integrated monitoring channels, e.g. an
error in the result and data comparison.
If at least one safety function is selected, then the stop response SS1 or SS1E takes place after
time p9555.
From V6.3 and higher, parameter p9561 "SI SCF stop response", is available, with which the
user can set whether an SS1 or a SS1E should be initiated after SCF. Time p9555 therefore
delays the transition to the stop responseSS1 or SS1E.
• Stop response STO or SS1
The converter detects a limit violation, for example involving the Safely-Limited Speed (SLS)
function. The stop response is settable.
If stop response SS1 is set, stop response STO automatically follows when the motor comes
to a standstill.
It is not possible to select a stop response externally, for example via PROFIsafe.
All stop responses bring the motor to a standstill.

14.12.11.2 Priority of stop responses and stop functions
Overview
If multiple Safety Integrated Functions or stop responses are active at the same time, the priority
of each function determines the behavior of the motor.
