A.1.8 Time synchronization between the control and converter
In the factory setting, SINAMICS drives use an operating hours counter. Based on the
operating hours, the SINAMICS drive saves alarms and warnings that occur. Using this
method, it is not possible to have a comparable timestamp between various converters.
In order to obtain a comparable timestamp between several converters, you must change over
the operating hours counting to time in the UTC format and synchronize with the time master
(control system).
This means that the events of all bus nodes, which are synchronized with the control system
time, can be referenced with one another.
Benefits: Improved diagnostic options by having a comparable time stamp of the bus nodes
involved.
