6.5 Additional information on configuring the SINAMICS Integrated
SIMOTION D4x5-2
214 Commissioning and Hardware Installation Manual, 02/2012
Requirements
A message frame 39x is required for the time synchronization. If the automatic PROFIdrive
message frame setting is selected for the Control Unit, this message frame is used
automatically (see Section Calling the drive wizard (Page 160), Standard/Automatic setting).
If the message frames are
specified manually, message frame 39x must be set up (see
Section Message frame configuration (Page 244)).
So that drive
units can be synchronized with the SIMOTION time, they must support
message frame 39x and the UTC time format.
The following Control Units support time synchronization:
● SINAMICS Integrated of the SIMOTION D
● CX32/CX32-2 controller extensions
● SINAMICS S120, CU310, CU310-2, CU320, CU320-2 Control Units, connected via
PROFIBUS or PROFINET
Synchronizing the SINAMICS clock
Proceed as follows to convert the SINAMICS clock to UTC format and to synchronize this
with the SIMOTION clock:
1. Call the D4x5-2 context menu in the project navigator.
2. Select the "Properties..." entry in the context menu.
3. Select the "Perform time synchronization with SINAMICS drive units" option in the
"Settings" tab of the "Properties - D4x5-2" dialog box.
Note
This setting is automatically activated for new projects as of V4.2 and applies for all drive
units connected to the D4x5-2. The SINAMICS clock is automatically synchronized with the
SIMOTION clock for all drive units with configured message frame 39x.
The first time synchronization is performed after the SIMOTION D Control Unit has reached
the RUN operating mode.
To compensate for deviations between the SIMOTION and SINAMICS clocks, the time of
day is automatically resynchronized at regular intervals.
Via the system variable _driveStates.allClocksSynchronized on the D4x5-2 device, the user
program can query whether the automatic time synchronization is activated (=YES) or
deactivated (=NO).
Before the first synchronization, alarms and messages are stored with the time stamp valid
in the SINAMICS at this time, all subsequent alarms and messages with the synchronized
time.
The first time synchronization after switching on is entered with the status of the operating
hours counter and the time (UTC time, synchronized with SIMOTION) in the diagnostics
buffer of the drive (e.g. SINAMICS Integrated).
