A parameter cannot be changed
When must you not change a parameter?
The converter indicates why it currently does not permit a parameter to be changed:
You have attempted to change
a read-only parameter.
You must change to quick
commissioning to set this pa-
rameter.
You must turn the motor off to
set this parameter.
The operating state in which you can change a parameter is provided in the List Manual for
each parameter.
