Potential Standstill Mode issues

[nmaas87]

Dear all,
I tried the standstill mode example from the unidirectional examples.
Sadly, it seems like the standstill modes set have no effect.
Running the example switches through the modes while you cannot feel any change physically.
If I add the SettingsAndStatus example after each change, I can see that the standstill mode will always be at "1", which means freewheeling.
Is there some issue or am I doing something wrong?
Thanks a lot :)
