If the command cannot be performed the slave sends
this response: 0111
Command cannot be performed
and gives the following fault report in the parameter
value (PWE):
Response

0 The parameter number used does
not exist
1 There is no write access to the de-
fined parameter
2 Data value exceeds the parame-
ter's limits
3 The sub index used does not exist
4 The parameter is not the array type
5 The data type does not match the
defined parameter
17 Data change in the defined param-
eter is not possible in the frequency
converter's present mode. Certain
parameters can only be changed
when the motor is turned off
