Table 6- 10
Response identifiers, inverter → control
AK
Description
0
No response
1
Transfer parameter value (word)
2
Transfer parameter value (double word)
3
Transfer descriptive element
1)
4
Transfer parameter value (field, word)
2)
5
Transfer parameter value (field, double word)
2)
6
Transfer number of field elements
7
Inverter cannot process the request.
In the most significant word of the parameter channel, the inverter sends an error number to
the control, refer to the following table.
8
No master controller status / no authorization to change parameters of the parameter chan-
nel interface
1)
The required element of the parameter is specified in IND (2nd word).
2)
The required element of the indexed parameter is specified in IND (2nd word).
Table 6- 11 Error numbers for response identifier 7
No.
Description
00 hex
Illegal parameter number (access to a parameter that does not exist)
01 hex
Parameter value cannot be changed (change request for a parameter value that cannot be
changed)
02 hex
Lower or upper value limit exceeded (change request with a value outside the value limits)
03 hex
Incorrect subindex (access to a subindex that does not exist)
04 hex
No array (access with a subindex to non-indexed parameters)
05 hex
Incorrect data type (change request with a value that does not match the data type of the
parameter)
06 hex
Setting not permitted, only resetting (change request with a value not equal to 0 without
permission)
07 hex
Descriptive element cannot be changed (change request to a descriptive element error
value that cannot be changed)
0B hex
No master control (change request but with no master control, see also p0927.)
0C hex
Keyword missing
11 hex
Request cannot be executed due to the operating state (access is not possible for tempo-
rary reasons that are not specified)
14 hex
Inadmissible value (change request with a value that is within the limits but which is illegal
for other permanent reasons, i.e. a parameter with defined individual values)
65 hex
Parameter number is currently deactivated (depending on the mode of the inverter)
66 hex
Channel width is insufficient (communication channel is too small for response)
68 hex
Illegal parameter value (parameter can only assume certain values)
6A hex
Request not included / task is not supported (the valid request identifications can be found
in table "Request identifications controller
→ inverter")
6B hex
No change access for a controller that is enabled. (The operating state of the inverter
prevents a parameter change)
