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) is reported in the drive if this rule is violated.

2.The master application cycle (T mapc), which corresponds to the servo cycle, must be an integer multiple of the speed controller cycle. Error A01902 (7) is reported in the drive if this rule is violated. The smallest-possible T mapc so results from the smallest common multiple of the DP cycle and the speed controller cycle.

If the master application cycle = 1, this means that the DP cycle is also an integer multiple of the speed controller cycle.

3.The DP cycle must be an integer multiple of the basic cycles r0110[x] (DRIVE-CLiQ basic sampling rates). Error A01902 (13) is reported in the drive if this rule is violated.

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!

An overview of errors reported in SINAMICS Integrated is provided in the SINAMICS S Parameter Manual
