Resetting the time
Requirement:
● SIMOTION D4x5-2: As of SIMOTION V4.3
● SINAMICS S120: As of SINAMICS V4.5
● SINAMICS S110: Not available (SINAMICS V4.4)
A threshold value is defined via parameter cu.p3109 and is effective as follows:
● In the case of negative time jumps less than the threshold value (p3109), the time is
halted (for details, see "Compensation of runtime deviations").
● In the case of negative time jumps greater than the threshold value (p3109), the time is
reset.
Default setting: cu.p3109 = 100 ms
This means that in the case of negative time jumps greater than 100 ms, the time is reset.
The default value is configured so that normal runtime deviations (drift of the quartzes)
are below the threshold value.
If the SIMOTION clock is reset by more than 100 ms, this is interpreted as a "specific
reset of the time" and the time of the drives is also immediately reset.
If the real-time clock is reset by more than 60 seconds, a diagnostics buffer entry is also
made in the drive:
Time correction (reset) by <correction value> seconds
After a resynchronization (negative time jump greater than the threshold value)
cu p3107[0..1] the UTC time after synchronization
cu p3107[2..3] the UTC time before synchronization
is displayed in the parameter, whereby [0] and [2] are milliseconds and [1] and [3] are days.
Note
The diagnostics buffer entries are not converted to the new time when the time is changed.
