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
Channel width is insufficient
Illegal parameter value
Request not included / task is not supported After request ID 5, 10, 15
No write access with enabled controller
Changed minimum/maximum not achieved
or exceeded
The available access authorization does not
cover parameter changes.
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
–
Description cannot be changed
Change request without "master control"
mode (see P0927)
–
The current inverter status 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.
The operating state of the inverter prevents
a parameter change
The maximum or minimum can be limited
further during operation.
