BONFIGLIOLI Vectron Active Cube - Examples of Writing Parameters

12.3.1.2 Examples of writing parameters
Example 1
Write parameter Rated Speed 372 (type: uint) in data set 2 with the parameter value
2980.
Index = 372 + 0x2000 = 0x2174, value = 2980 = 0x0BA4

If an error occurs during the writing process, the corresponding error code is given in
Bytes 4 … 7. Check chapter 11.3.3 for the error code list for SDO abort.
Using Write accesses for parameters (objects 0x2nnn = index), the sub-index is used
to define the Write access into EEPROM or RAM. Please refer to chapter
12.3.1
“Handling of data sets/cyclic writing”.
