Response IDs (slave → master)
Response ID Description
0 No response
1 Transfer parameter value (word)
2 Transfer parameter value (double word)
3 Transfer descriptive element
4 Transfer parameter value (array, word)
5 Transfer parameter value (array, double word)
6 Transfer number of array elements
7 Request cannot be processed, task cannot be executed (with error number)
8 No master controller status / no parameter change rights for PKW interface
Error numbers in response ID 7 (request cannot be processed)
No. Description
0 Illegal PNU (illegal parameter number; parameter number not available)
1 Parameter value cannot be changed (parameter is read-only)
2 Lower or upper limit violated (limit exceeded)
3 Wrong sub-index
4 No array
5 Wrong parameter type / incorrect data type
6 Setting is not allowed (parameter value can only be reset to zero)
7 The descriptive element is not changeable and can only be read
9 Descriptive data not available
10 Access group incorrect
11 No parameter change rights. See parameter P0927. Must have status as master control.
12 Incorrect password
17 The current inverter operating status does not permit the request processing
18 Other error
20 Illegal value. Change request for a value which is within the limits, but it is not allowed for other reasons
(parameter with defined single values)
101 Parameter is currently deactivated; parameter has no function in the present inverter status
102 Communication channel width is insufficient for response; dependent on the number of PKW and the maximum
net data length of the inverter
104 Illegal parameter value
105 Parameter is indexed
