Supported Functions - Siemens SINAMICS S120 Function Manual

For safety reasons, you can only configure the Safety-relevant parameters of the first channel
with the Startdrive commissioning tool while offline. Startdrive copies the parameters of the
second channel automatically.
Since Startdrive generates the safety-relevant parameters of the second channel by copying,
this manual contains only the parameters of the first channel. You will find the relevant
parameters of the 2nd channel in the parameter description, e.g. in SINAMICS S120/S150 List
Manual.
On faults and alarms, only the error number of the 1st channel is stated.
Switch-off signal paths
Two independent switch-off signal paths are available. All switch-off signal paths are low-
active, thereby ensuring that the system is always switched to a safe state if a component fails
or in the event of an open circuit.
If a fault is discovered in the switch-off signal paths, the "Safe Torque Off" function is activated
and a system restart inhibited.
Monitoring cycle
The safety-relevant drive functions are executed cyclically in the monitoring cycle.
The safety monitoring cycle lasts a minimum of 4 ms. Increasing the current controller cycle
(p0115) also increases the safety monitoring cycle.
Data cross-check
A cyclic cross-check of the safety-related data in the two monitoring channels is carried out. If
any data is inconsistent, a stop response is triggered with any Safety function.
