12.6.4 Illegal Response When Reading Parameters
Command Description Function
Data
Slave parameters
response
The highest-order byte
changes into 1.
Command meaning:
0001: Illegal function code
0002: Illegal address
0003: Illegal data
0004: Slave fault
note 2
Note 2: Illegal response 0004 appears below two cases:
Do not reset inverter when inverter is in the malfunction state.
Do not unlock inverter when inverter is in the locked state.
Additional Remarks
Expressions during communication process:
Parameter Values of Frequency
＝
actual value X 100
Parameter Values of Time=actual value X 10
Parameter Values of Current=actual value X 100
Parameter Values of Voltage=actual value X 1
Parameter Values of Power (100A)=actual value X 1
Parameter Values of Power (1018)=actual value X 10
Parameter Values of Drive Ratio=actual value X 100
Parameter Values of Version No. =actual value X 100
Instruction: Parameter value is the value sent in the data package. Actual value is the actual
value of inverter. After PC/PLC receives the parameter value, it will divide the corresponding
coefficient to get the actual value.
NOTE: Take no account of radix point of the data in the data package when PC/PLC transmits
command to inverter. The valid value is range from 0 to 65535.
