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
● The parameters are not changed until the safety commissioning mode has been exited (i.e.
when p0010 is set ≠ 95).
● 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 initiates "No stop reaction"
as default setting.
● Once the parameterized time has elapsed, STOP A (immediate safety pulse cancellation) is
initiated by fault F01600 or F30600 (SI STOP A initiated). The default setting for p9658 and
p9858 is 0, i.e. STOP F immediately results in STOP A.
● Both parameters are included in the crosswise data comparison and must therefore be set to
identical values. A difference of one safety monitoring clock cycle is tolerated for the values.
Sets the time to carry out the forced checking procedure and test the safety switch-off signal paths
● After this time has expired, using alarm A01699 (SI CU: Switch-off signal paths must be tested),
the user is requested to test the switch-off signal paths (i.e. select/deselect STO).
● 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
Specified checksum on the Motor Module
The current checksums for the Safety parameters that have undergone a checksum check are
displayed as follows:
● Actual checksum on the Control Unit: r9798
● Actual checksum on the Motor Module: r9898
By setting the actual checksum in the parameter for the specified checksum, the commissioning
engineer confirms the Safety parameters in each monitoring channel.
Set the new Safety password
Enter a new password
Confirm new password
In the SINUMERIK environment we recommend that an axis-specific password is not used. The
commissioning area is sufficiently protected using the password protection at the HMI, and an axis-
specific password makes further commissioning steps more difficult.
● The new password is not valid until it has been entered in p9762 and confirmed in p9763.
● As of now, you must enter the new password in p9761 so that you can change Safety
parameters.
● Changing the Safety password does not mean that you have to change the checksums in p9799
and p9899.
