When debounce p10117 is active, the discrepancy time is directly specified by the debounce time.
If the period of a cyclic switching pulse corresponds to twice the debounce time, then the following formulas should
be checked.
- p10102 < p10117 + 1 ms - td
- p10102 > td
- p10102 >= 12 ms
Example:
For a 110 ms switching frequency and p10117 = 0, the maximum discrepancy time that can be set is as follows:
p10102 <= (110/2 ms) - 12 ms = 43 ms
Rounded off, p10102 <= 36 ms is obtained (as the discrepancy time is rounded off as a multiple of 12 ms).

A30788 Automatic test stop: wait for STO deselection via SMM
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: NONE
Cause: The automatic test stop was not able to be carried out after powering up.
Possible causes:
- the STO function is selected via Safety Extended Functions.
- a safety message is present, that resulted in a STO.
Remedy: - Deselect STO via Safety Extended Functions.
- remove the cause of the safety messages and acknowledge the messages.
The automatic test stop is performed after removing the cause.
C30798 SI Motion P2: Test stop for motion monitoring functions running
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The forced checking procedure (test stop) for the safe motion monitoring functions is currently in progress.
Remedy: Not necessary.
The message is automatically withdrawn when the test stop has been completed.
Note:
SI: Safety Integrated
C30799 SI Motion P2: Acceptance test mode active
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The acceptance test mode is active.
Remedy: Not necessary.
The message is withdrawn when exiting the acceptance test mode.
N30800 (F) Power unit: Group signal
Message class: Power electronics faulted (5)
Reaction: OFF2
Acknowledge: NONE
Cause: The power unit has detected at least one fault.
Remedy: Evaluate the other messages that are presently available.
