2.2 List of parameters
SINAMICS G120 CU230P-2 Control Units
386 List Manual, 04/2018, A5E33838102
For index 1:
Displays the external firmware version (e.g. 04040000 -> 4.4).
For automation systems with SINAMICS Integrated this is the runtime version of the automation system.
For index 2:
Displays the internal firmware version of the parameter backup.
With this CU firmware version, the parameter backup was saved, which was used when powering up.
Description: Displays the sampling times currently present on the drive unit.
r7901[0...63]: sampling times of hardware time slices.
r7901[64...82]: sampling times of software time slices.
r7901[x] = 0, means the following:
No methods have been registered in the time slice involved.
Note: The basis for the software time slices is T_NRK = p7901[13].
Description: Displays the number of hardware sampling times that can still be assigned.
These free sampling times can be used by OA applications such as DCC or FBLOCKS.
Note: OA: Open Architecture
Description: Sets and displays the time on the real-time clock in hours, minutes, and seconds.
The time is stored in the internal clock block in the drive and continues to run even if the supply voltage for the
Control Unit is interrupted (for approx. 5 days).
Index: [0] = Hour (0 ... 23)
[1] = Minute (0 ... 59)
[2] = Second (0 ... 59)
Note: The time from p8400 and p8401 is used to display the fault and alarm times.
When displaying the fault time and alarm time, the switchover to daylight saving time is not taken into account.
The parameter is not reset when the factory setting is restored (p0010 = 30, p0970).
The time is entered and displayed in 24-hour format.
RTC: Real-time clock
