3 Functions
If the response ID has the value 7 (request cannot be executed), then a fault
number is saved in parameter value 2 (PWE2). The fault numbers are
documented in the following table.

Fault numbers for the response ID "Request cannot be executed"
Significance
Inadmissible legal parameter number (PNU); if PNU is not available
Parameter value cannot be changed; if the parameter is a visualization parameter
Lower or upper limit exceeded
Erroneous sub-index
No array
Incorrect type of data
Setting not permitted (can only be reset)
Descriptive element cannot be changed; not possible
No operator control rights
Key word missing, device parameter: 'access keyl' and/or 'special parameter access' not
appropriately set
No text array available
Request cannot be executed due to operating states;
The frequency inverter state presently does not allow the request that was issued
Parameter number presently de-activated;
In the present frequency inverter state, the parameter has no function (e.g. closed-loop
control type)
Channel width too small: Only for short channels;
the parameterized length of the PKW area has been selected too large due to the
restrictions in the device. This fault message can only occur for the USS protocol on the
technology module T 100 if basic device parameters are accessed from this interface
Incorrect PKW number; only for G-SST 1/2 and SCB interface (USS).
The fault number is transferred in the following two cases:
If the request involves all indices of an indexed parameter (request index equal to
255) or the complete parameter description is requested and a variable telegram
length was not parameterized.
If, for the request issue, the parameterized number of PKW data in the telegram is
too low (e.g.: Changing from a double word and PKW number equal to 3 (words).
Parameter value not permissible;
This fault number is transferred if the parameter value – that is to be transferred – is not
assigned any function in the device or at the time of the change it is not able to be
transferred for internal reasons (although it lies within the limits).
The parameter is indexed
e.g. request: 'PWE, change word' for indexed parameters
Request not implemented
New minimum value
New maximum value
No BOP/AOP display,
Parameter cannot be displayed on the BOP or AOP.
The 'BOP/AOP key word' does not match the parameter access stage.
