No. Parameter Description/comments

p9658 = "Value"
p9858 = "Value" Set transition period from STOP F to STOP A.
Transitional period from STOP F to STOP A on Control Unit
Transitional period from STOP F to STOP A on Motor Module
•
The parameters are not changed until safety commissioning mode has been exited
(i.e. when p0010 ≠ 95 is set).
• STOP F is the fault reaction that is initiated when the data cross-check is violated as a
result of fault F01611 or F30611 (SI: defect in a monitoring channel). STOP F
normally triggers "No fault reaction".
• After the parameterized time has expired, STOP A (immediate safety pulse inhibit) is
triggered by the fault F01600 or F30600 (SI: STOP A triggered).
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 identical. A difference of one safety monitoring clock cycle is tolerated for the
values.
9 p9659 = "Value" Time for carrying out forced dormant error detection and testing the safety switch-off
paths.
•
After this time has expired, the user is requested to test the switch-off paths as a
result of alarm A01699 (SI CU: Necessary to test the switch-off signal paths) (i.e.
select/de-select STO).
• The commissioning engineer can change the time required for carrying out the forced
dormant error detection and testing the safety switch-off paths.

p9799 = "r9798"
p9899 = "r9898"
Adjust specified checksums.
Specified 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.
This procedure is performed automatically when STARTER and the commissioning
Wizard for SINAMICS Safety Integrated are used.

p9762 = "Value"
p9763 = "Value"
Set the new Safety password.
Enter a new password.
Confirm the new password.
•
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.
