Fig. 2.29 Request of a safety function (example of STO) / Restart
Restart after error acknowledgment
The error management can also request the STO function as an error response (via ERR_STO_RSF sig­
nal). As shown in Fig. 2.27, the request is fed into the STO function.
For the drive to restart after an acknowledged error, a restart must take place via VIN_STO_CSF or the
parameter "Automatic restart permitted" (P0A.00) must be set for an automatic restart. This also ap­
plies in a similar manner for the safety functions SS1, SS2 and SBC, which can be configured as an error
response.
Restart after termination of SS1
The SS1 function requests STO at the end of its sequence via the control input SS1_STO_RSF.
As can be seen in Fig. 2.29, the STO request is automatically deactivated when the request for the SS1
function no longer exists. The request of the STO function does not need to be deactivated separately.
This also applies when the SS1 function is requested in case of error: The error must be acknowledged
and SS1 deactivated. STO does not need to be deactivated separately.
Restart after termination of SBC
The logic for requesting and terminating the SBC function is basically like the logic for requesting STO
(è Section 2.5.2, Fig. 2.16)
In addition to the standard logic, SBC can also be activated via direct control signals from STO
(STO_SBC_RSF) and SS1 (SS1_SBC_RSF). On restarting from STO or SS1, the automatic restart from
SBC also takes place.
This means that it is possible to implement different restart conditions, although the
same safety functions are being used:
– direct request of SBC, restart, for example, via LIN_D49_RISING_EDGE,
– indirect request, for example via SS1, restart from SBC together with restart from
SS1, as soon as its restart condition has been met (e.g. LIN_D40).
