Note
Vector drives in chassis format can also be operated with a current controller sampling time
of 400 µs (among other settings).
In a SIMOTION context, the following should be considered:
●
A current controller sampling time of 400 µs is only possible if control is via a
SINAMICS S120 control unit, which is not operated isochronously via
PROFIBUS/PROFINET on SIMOTION D.
● If the bus is operated isochronously, only cycles with an integer multiple of 125 µs are
possible (instead of 400 µs, so 375 µs or 500 µs, for example).
● The PROFIBUS Integrated of a SIMOTION D410 is always isochronous. This means that
a current controller sampling time of 400 µs is not possible.
● With CU parameter p0092 = 1, the sampling times are preassigned in a way that enables
isochronous operation with a control system.
Output cams / measuring inputs with vector drives
With vector drives, the cycle clock ratios (current controller cycle clock, speed controller
cycle clock, sampling time of the inputs/outputs, etc.) depend on the number of vector drives,
or with chassis units also on the device type used.
Note the information in Section Current controller cycle clocks <> 125 µs / use of output
cams and measuring inputs (Page 100).

Additional information on quantity structures and cycle clock settings can be found in the
SINAMICS S120 Function Manual.
4.4.3 Set time of day
Time on SIMOTION (real-time clock)
SIMOTION D410 features an integrated real-time clock. All events on a module (alarms,
messages, etc.) are "time-stamped" based on the time shown by this real-time clock.
To set the clock from SIMOTION SCOUT, select the SIMOTION D410 in the project tree,
followed by "Target System" > "Set Time".
Alternatively, the clock can be set using the "rtc" system function block.
