Assigning parameters to make AOP30 time-of-day master

The AOP30 contains an integrated real-time clock. The SINAMICS DCM system time can be

synchronized with this real-time clock.

Activate this function:

● On the AOP30 in the "Menu" – "Commissioning / Service" – "AOP settings" – "Date and

Time" menu command activate to "AOP sets clock in SINAMICS".

The current time in the AOP30 is then written into the drive.

In the display for faults and alarms, the time stamp is now displayed in the format YY-MM-

DD hh:mm in real-time. The time stamp mode and the current time can be read from the

parameters p3100, p3102 and p3103. For details, please see the SINAMICS DCM List

The current time is resynchronized at each power-up. (The AOP30 must be switched on

together with the drive). During uninterrupted duty, synchronization takes place every day at
