[Cause]
When the robot arm fracture is disabled, the robot arm fracture signal turns off (not the robot arm fracture state). The settings for robot breakage are incorrect. The number in parentheses indicates the action group number.
[Countermeasure]
1. Confirm whether the robot hand break signal circuit is connected to the robot. When the robot break signal circuit is connected or the robot break signal is short-circuited, set robot break to enabled.
2. Press the alarm release key to release the alarm. For details, please take appropriate measures according to "Troubleshooting based on alarm codes" in the control device maintenance manual corresponding to the control device used.
