Rules For Simotion D410 Dp - Siemens SIMOTION D410 Series Commissioning Manual

The PROFIBUS DP interface can also be operated in isochronous slave mode. In this
constellation system clocks are based on the clock signals received at the slave interface. A
substitute clock of a duration equivalent to the configured clock is generated internally if the
isochronous slave interface has not received a clock signal.
The clock settings are included in the project download to SIMOTION D410 DP and are
adjusted according to specification.
At a PROFIBUS DP interface operated in isochronous slave mode you can also step down
the clock ratio for synchronization with SINAMICS Integrated. This reduction of the clock
ratio at the isochronous slave interface for synchronization with SINAMICS Integrated allows
the operation of a DP cycle at the slave interface which is equivalent to an integer multiple
SINAMICS Integrated. This reduction can be set up by setting an integer multiple of the
SINAMICS Integrated DP cycle as the DP cycle for the DP interface (X21) in HW Config.
The rule is checked in HW Config.

Rules for SIMOTION D410 DP

Rules for synchronizing the system clocks
You must conform to the following rules when setting the DP cycle and SINAMICS clocks:
1. The DP cycle must be an integer multiple of the current controller cycle. Error A01902 (2)
2. The master application cycle (T
3. The DP cycle must be an integer multiple of the basic cycles r0110[x] (DRIVE-CLiQ basic

integer multiple of the speed controller cycle. Error A01902 (7) is reported in the drive if
this rule is violated. The smallest-possible T

If the master application cycle = 1, it follows that the DP cycle is also an integer multiple
of the speed controller cycle.
sampling rates). Error A01902 (13) is reported in the drive if this rule is violated.
You can determine parameter r0110[x] using the expert list in SIMOTION SCOUT (select
the "Control_Unit" from "SINAMICS_Integrated" in the Project Navigator, and then open
the "Expert List" by selecting the "Expert" command from the shortcut menu).
Note
In addition to the rules mentioned, also observe the rules outlined below. These rules
apply both to SIMOTION D410 DP and to SIMOTION D410 PN!
