I/O device or host computer is the same as that of the CNC.
(baud rate, stop bits, etc.)
If they are not the same, change the setting.
(ii) When spare I/O device presents, check whether it is
possible to realize communication using the spare I/O
device.
(c) Main board or serial communication control module is faulty
(i) When parameter No.0020 is 0, 1, or 2 (JD56A, JD36A of
