If they are different, use the same serial number of the robot and the controller.
A2-2
Is the power connected properly? (Are both EMG terminal and REM terminal closed?)
If not, connect the power properly.
A2-3
Check if the cables between robot and controller are connected properly.
Disconnect them and connect again. Make sure that connection part is locked properly.
If cables are not connected, connect first and lock and check again.

If other status is returned, check the error code (refer to the operation manual), remove the cause, and check again.
A2-6
Check if the robot is initialized. Confirm the origin search (Command $1PT) has been completed.
Origin is set with 3-axis: 1101 / 4-axis: 1111/ 5-axis: 11111.
