Configuring the fieldbus
6.1 Communication via PROFIBUS
Inverter with CU240B-2 and CU240E-2 Control Units
Operating Instructions, 01/2011, FW 4.4, A5E02299792B AB
113
If the response identifier is 7 (request cannot be processed), one of the error numbers listed
in the following table will be saved in parameter value 2 (PWE2).
Table 6- 12 Error numbers for the response "Request cannot be processed"
No. Description Comments
0 Impermissible parameter number (PNU) Parameter does not exist
1 Parameter value cannot be changed The parameter can only be read
2 Minimum/maximum not achieved or
exceeded
–
3 Wrong subindex –
4 No field An individual parameter was addressed
with a field request and subindex > 0
5 Wrong parameter type / wrong data type Confusion of word and double word
6 Setting is not permitted (only resetting) –
7 The descriptive element cannot be changed Description cannot be changed
11 Not in the "master control" mode Change request without "master control"
mode (see P0927)
12 Keyword missing –
17 Request cannot be processed on account of
the operating state
The current inverter status is not
compatible with the received request
20 Illegal value Modification access with a value which is
within the value limits but which is illegal for
other permanent reasons (parameter with
defined individual values)
101 Parameter number is currently deactivated Dependent on the operating state of the
inverter
102 Channel width is insufficient Communication channel is too small for
response
104 Illegal parameter value The parameter can only assume certain
values.
106 Request not included / task is not supported After request ID 5, 10, 15
107 No write access with enabled controller The operating state of the inverter prevents
a parameter change
200/201 Changed minimum/maximum not achieved
or exceeded
The maximum or minimum can be limited
further during operation.
204 The available access authorization does not
cover parameter changes.
