Time stamp mode

The mode for the time stamp can be set via parameter p3100. The following modes are

Also note the following information when setting a time stamp:

Time stamp settings depending on the firmware version

If a project is upgraded from firmware V4.6 to V4.7 then the time stamp settings for the old

project are retained. The times displayed for the error messages do not therefore differ from

those in the old firmware version.

If a new project is created with a firmware version > V4.7, the factory setting for the p3100 = 2

and therefore a different time basis for error messages. If the response required is the one for

versions older than V4.7 then p3100 = 0 should be set.

Synchronizing time stamps

If a control system and several drive devices are connected through a bus, then the different

time stamps can be synchronized to the time stamp of the control system (= time-of-day

master). Detailed information on this is provided in the manual "SINAMICS S120 Function

Manual Communication" in the chapter "Time synchronization between the control and

Drive functions

p2114 was used with the setting p3100 = 0.
