Rules For Simotion D410 Pn - Siemens SIMOTION D410 Commissioning Manual

Setting the DP cycle in HW Config
Set the DP cycle of SINAMICS Integrated in HW Config. In HW Config, double-click the
SINAMICS drive at the integrated PROFIBUS. The "DP Slave Properties" dialog box opens.
You can synchronize the DP cycle of SINAMICS Integrated in the "Isochronous mode" tab.
Table 4-4

SINAMICS Integrated always operates in isochronous mode. The cyclic tasks of SIMOTION
are therefore always in synchronism with SINAMICS Integrated.
Setting the send cycle in HW Config
The PROFINET send cycle always forms the basis for the SIMOTION cycles if the "IRT
communication" real-time class is set and data are being transferred. Set the send cycle in the
"Domain Management" dialog box of HW Config. Open this dialog by selecting the "Edit" >
"PROFINET IO" > "Domain Management ..." command in HW Config.
The set PROFINET send cycle is displayed in SIMOTION SCOUT as "Bus data cycle" in the
"System Clocks - D410..." dialog box. Select the SIMOTION D410 PN in the project tree, and
then select the "Set system clocks" option in the "Target system" > "Expert" menu.
The PROFINET interface supports send cycle times within the range 0.5 ms < send cycle <
4 ms. The maximum configurable resolution is 0.125 ms.
Note
If there are I/O devices with RT class "RT" in a sync domain, only the send cycle clock settings
0.5 ms; 1 ms; 2 ms and 4 ms are available.
The table below shows which ratios you can set for the system clocks of SIMOTION D410 PN
based on the DP cycle of SINAMICS Integrated or on the PROFINET send cycle.

The minimum servo cycle length that can be set is 2 ms.

Rules for SIMOTION D410 PN

Rules for using the PROFINET send cycle
If the PROFINET send cycle is the basis for the cycles, ensure that the DP cycle of the
SINAMICS Integrated and the servo cycle are equal.
