[Cause]
During the gun sticking detection processing, the gun sticking detection data could not be received from ROBOWELD.
[Countermeasure]
1. On the port setting interface, confirm that the port 4 (RS-422) is set to ROBOWELD.
2. Check whether there is any abnormality in the communication cable between the welding power source part and the robot control device part of ROBOWELD.
3. Increase the value of system variables $RBWLD_CFG.$WSRCV_TRIES and $AWEUPR[1].$WSTK_MON_DLY.
4. If the problem cannot be solved by the above method, it is possible that the relay in the welding equipment has been deposited. Please consult the maintenance service department.
