5. Exception response
When the drive is using the communication connection, if an error occurs, the drive responds
to the error code and sets the highest bit (bit 7) of code to 1 (function code AND 80H) then
responds to the control system to signal that an error occurred.
If the keypad displays “CE-XX” as a warning message, “XX” is the error code at that time.
Refer to the table of error codes for communication error for reference.
Example:
ASCII mode RTU mode:
STX ‘:’ Address 01H
Address
‘0’ Function 86H
‘1’ Exception code 02H
Function
‘8’ CRC CHK Low C3H
‘6’ CRC CHK High A1H
Exception code
‘0’
‘2’
LRC CHK
