Explanation of exception codes:
Exception code
Explanation
01
Illegal function code:
The function code received in the command message is not available for the AC
motor drive.
02
Illegal data address:
The data address received in the command message is not available for the AC
motor drive.
03
Illegal data value:
The data value received in the command message is not available for the AC
motor drive.
04
Slave device failure:
The AC motor drive is unable to perform the requested action.
10
Communication time-out:
If Pr.09.03 is not equal to 0.0, and Pr.09.02 = 0–2, and there is no communication
on the bus during the time-out detection period (Pr.09.03), the keypad displays
“cE10”.
7. Communication program for a PC:
The following is a simple example of how to write a communication program for Modbus ASCII mode on a
PC in the C language.
