101 
● General purpose output, can be configured in programs to output 
signals. 
【Motion Stopped】 
● The system enters an emergency stop state and outputs a low level 
signal. Otherwise, the output is high. This safety function will come in 
pairs for redundancy. 
The actions that conform to the emergency stop are: 
1. When the Emergency Stop button of the control box is pressed, the 
power supply of the robotic arm is cut off. 
2. Stop button of xArm Studio and Emergency stop code block of 
Blockly. 
3. IO input is set to an emergency stop. 
4. Emergency stop API of SDK. 
【In motion】 
● When the robotic arm is in motion, the output is low. The robotic arm 
outputs a high level when in a fixed position. This safety related IO 
will come in pairs. 
【Error】 
● When the robotic arm reports an error, the output is low. 
Otherwise, the output is high.
