SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
4.6 Commissioning the STO, SBC and SS1 functions
Description and comments
Sets the transition time from STOP F to STOP A
Transition time from STOP F to STOP A on the Control Unit
Transition time from STOP F to STOP A on the Motor Module
S
The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 0 95 is set).
S
STOP F is the stop response initiated by fault F01611 or F30611 (SI defect
in a monitoring channel) when the crosswise data comparison is violated.
STOP F normally initiates "No stop response".
S
Once the parameterized time has elapsed, STOP A (immediate safety
pulse cancellation) is initiated by fault F01600 or F30600 (SI STOP A initi-
ated).
The default setting for p9658 and p9858 is 0, i.e. STOP F immediately re-
sults in STOP A.
S
Both parameters are contained in the crosswise data comparison and must,
therefore, be "identical". A difference of one safety monitoring clock cycle is
tolerated for the values.
Sets the time to carry out the forced checking procedure and testing the
safety shutdown paths
S
After this time has expired, using alarm A01699 (SI CU: Shutdown paths
must be tested), is requested to test the shutdown paths (i.e. select/dese-
lect STO).
S
The commissioning engineer can change the time required for carrying out
the forced checking procedure and testing the safety switch–off paths.
Adapt the specified reference checksums
Reference checksum on the Control Unit
Reference checksum on the Motor Module
The actual checksums for the safety parameters that have undergone a
checksum check are displayed as follows:
S
Actual checksum on the Control Unit:
S
Actual checksum on the Motor Module:
By setting the actual checksum in the parameter for the specified reference
checksum, the commissioning engineer confirms the safety parameters in each
monitoring channel.
Sets a new safety password
Enter a new password
Confirm the new password
In the SINUMERIK environment we recommend that an axial password is not
used. The commissioning area is sufficiently protected using the password
protection at the HMI and an axial password makes further commissioning
steps more difficult.
S
The new password is not valid until it has been entered in p9762 and con-
firmed in p9763.
S
From now on you must enter the new password in p9761 so that you can
change safety parameters.
S
Changing the safety password does not mean that you have to change the
checksums in p9799 and p9899.
