Error messages if the order cannot be executed
In the response label "Order cannot be executed" (AK = 7), then an error message is added to the
parameter value (PWE2) of the inverter response. For the meanings of the values transferred, please
refer to the following table.
AK Meaning
0 Invalid parameter number
1 Parameter value cannot be changed
2 Lower or upper value limit exceeded
3 Incorrect sub-index
4 No array
5 Invalid data type (at present only for SK 700E)
6 Only resettable (only 0 may be written)
7 Description element cannot be changed
9 Description data not present
201 Invalid order element in the last order received
202 Internal response label cannot be depicted

Sub-index
The structure and function of the parameter index (IND) depends on the type of parameter to be
transferred. For values which depend on the parameter set, the parameter set can be selected via Bits
0 and 1 of the Index (IND) (0 = parameter set 1, 1 = parameter set 2,...).
If the parameter to be processed is also an array parameter (e.g. position array for the POSICON
option), then the sub-index of the required parameter can additionally be accessed via Bit 2 to Bit 7 of
the sub-index (0 = array element 1, 1 = array element 2,…):
Array element Parameter set Index
5 (000101

) 2 (01
BIN
) 15

BIN
21 (010101
BIN
) 4 (11
BIN
) 57
HEX
= 0101 0111
BIN
If a parameter is not dependent on the parameter set, then Bits 0 -7 are used for the sub-index.
Please refer to the operating instructions for details of the structure of the individual parameters and
which values may be called up.
If the sub-index is used, nos. 6, 7, 8 or 11, 12 must be used as the order label, in order for the
sub-index to be effective.
