1. Drive communication address is assigned to PNU [1000].
2. Drive setting data is assigned to PNU [1001].
3. PNU [1003] is set to 0.
4. When PNU [1002] is set to 1, the SD300 Profinet communication
module references the values assigned at PNU [1000] and PNU
[1001] and writes the values to the drive internal parameters.
5. After writing the drive internal parameters, the SD300 Profinet
communication module saves the result to PNU [1003].
6. PNU [1003] is used to verify successful completion of writing
procedure.
The following diagram explains the parameter reading procedure.
