1) The required element of the parameter description is specified in IND (second word).
2) The required element of the indexed parameter is specified in IND (second word).
If the response ID = 7, then the inverter sends one of the error numbers listed in the
following table in parameter value 2 (PWE2).

Transfer parameter value (field, word)
Transfer parameter value (field, double word)
Transfer number of field elements
Request cannot be processed, task cannot be executed (with error number)
Error numbers for the response "Request cannot be processed"
Description
Impermissible parameter number (PNU)
Parameter value cannot be changed
Minimum/maximum not achieved or
exceeded
Wrong subindex
No field
Wrong parameter type / wrong data type
Setting is not permitted (only resetting)
The descriptive element cannot be
changed
Not in the "master control" mode
Keyword missing
Request cannot be processed on account
of the operating state
Illegal value
Parameter number is currently
deactivated

Comments
Parameter does not exist
The parameter can only be read
–
–
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"
mode (see p0927)
–
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.
