–
An individual parameter was addressed with
a field request and subindex > 0
Confusion of word and double word
Index is outside the parameter field[]
Description cannot be changed
Change request without "master control" state
–
The actual inverter operating state is not
compatible with the received request
Modification access with a value which is
within the value limits but which is illegal for
other permanent reasons (parameter with
defined individual values)
Dependent on the operating state of the
inverter
Communication channel is too small for
response
The parameter can only assume certain
values.
After request identifier 5,11,12,13,14,15
The operating state of the inverter prevents a
parameter change
The maximum or minimum can be limited
further during operation.
