If the command cannot be performed, the slave sends this response:
0111 Command cannot be performed
- and issues the following fault report in the parameter value (PWE):
PWE low (Hex)

Parameter Number (PNU)
Bits no. 0-11 transfer parameter numbers. The function of the relevant parameter is defined in the pa-
rameter description in the chapter How to Programme.
Index (IND)
The index is used together with the parameter number to read/write-access parameters with an index,
e.g. par. 15-30 Error Code. The index consists of 2 bytes, a low byte and a high byte.
NB!
Only the low byte is used as an index.

Fault Report
The parameter number used does not exit
There is no write access to the defined parameter
Data value exceeds the parameter's limits
The sub index used does not exit
The parameter is not the array type
The data type does not match the defined parameter
Data change in the defined parameter is not possible in the frequency conver-
ter's present mode. Certain parameters can only be changed when the motor
is turned off
There is no bus access to the defined parameter
Data change is not possible because factory setup is selected
