Bits no. 12-1 5 transfers parameter commands from master to slave and returns
processed slave responses to the master.
Parameter commands master=>slave
Bit no. Parameter command

0000Nocommand
0 0 0 1 Read parameter value
0 0 1 0 Write parameter value in RAM (word)
0 0 1 1 Write parameter value in RAM (double word)
1 1 0 1 Write parameter value in RAM and EEprom (double word)

0 1 1 1 Command cannot be performed
1111Texttransferred
If the command cannot be performed, the slave sends this response: 0111 Command cannot be
performed a nd issues the following fault report in the parameter value (PWE):
Response (0111) Fault Report
0 The parameter number used does not exist
1 There is no write access to the defined pa rameter
2 Data value exceeds the parameter’s l imits
3 The su b index us ed does not exist
4 The parameter is not the a rray type
5 The data type does not m atc h the defined parameter
17 Data ch ange in the defined parameter is not possible in the adjustable frequ en cy
drive’s prese nt mo de . Certain parameters can only be changed when the motor
is turned o ff
130 There is no bu s acc ess to the defined parameter
131 Data change is not pos si ble because factory Setup is selec ted
