 Modbus Address Encoding Method:
Refer to the function codes in the function code form. High 8 bit HI= function group number + 1; low 8 bit
LO= function code. Keep other register addresses that are not listed.
 List of Abnormality Codes
Abnormality
Code
Command code error
01H
Command codes other than 03H, 08H and10H
Register address error
None of the register addresses is registered
02H
Read the ENTER-confirmed special register[0X00FFH]
The communication function of the address is not initiated in the function code setting. (Note1)
Number error
03H Number of data read or written is not between 1 and 16
In the writing manner, the command data is not the bit number *2
Data setting error
21H
Upper and lower limit error during the control data & parameters input·
Writing manner error
Write the non-revisable parameters or read-only parameters in operation (Note 2)
22H Parameters write-protected (Note 3)
Write data into the special read register
Write in the case of CCF3, i.e. EEPROM fault
Write in the case of undervoltage
23H
Write parameters in the case of Uu
Write parameters from communication during the parameter processing
24H
At the time of fault resetting, system power supply cutoff or data saving
25H CRC check fault (Note 4)
Note 1: Set the P0.03 and P0.04 frequency setting as serial communication (when writing address 0002) or set P0.07
operation command control manner as serial communication (when writing address 0001).
Note 2: For parameters that can be set in operation, please refer to the function parameter list. If a parameter that
cannot be revised in operation but can be revised at the time of stop is to be revised, please stop the inverter and then
revise it.
Note 3: When parameters are write-protected and PF.01 is set as 1 or 2, please revise it as 0. Then all parameters can
be revised.
Note 4: In case of CRC 16 check fault, response will be given even if the system receiving is over, and 25H fault
will be reported to facilitate customer debugging.
