Response identifiers, inverter → control
Description
No response
Transfer parameter value (word)
Transfer parameter value (double word)
Transfer descriptive element
Transfer parameter value (field, word)
Transfer parameter value (field, double word)
Transfer number of field elements
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.
No master controller status / no authorization to change parameters of the
parameter channel interface
The required element of the parameter is specified in IND (2nd word).
The required element of the indexed parameter is specified in IND (2nd word).
Error numbers for response identifier 7
Description
Illegal parameter number (access to a parameter that does not exist)
Parameter value cannot be changed (change request for a parameter value that cannot be
changed)
Lower or upper value limit exceeded (change request with a value outside the value limits)
Incorrect subindex (access to a subindex that does not exist.)
No array (access with a subindex to non-indexed parameters)
Incorrect data type (change request with a value that does not match the data type of the
parameter)
Setting not permitted, only resetting (change request with a value not equal to 0 without
permission)
Descriptive element cannot be changed (change request to a descriptive element error
value that cannot be changed)
No master control (change request but with no master control, see also p0927.)
Keyword missing
Request cannot be executed due to the operating state (access is not possible for
temporary reasons that are not specified)
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)
Parameter number is currently deactivated (depending on the mode of the inverter)
Channel width is insufficient (communication channel is too small for response)
Illegal parameter value (parameter can only assume certain values)
