Speed monitor detected the speed over
A speed feedback exceeding the limit speed is detected by the speed monitoring function. Check the robot
movement or the monitoring speed setting. Or else, check the delay time (parameterSLSDLY) setting.
The robot motion command and the feedback are inconsistent.
The robot position command and the feedback position are inconsistent. Check the details of the robot
movement, the terminal load setting, or interference with the peripheral equipment.
The Safety Function is not normally executed
Turn the power OFF and ON once.
If the same error recurs, contact the manufacturer.
The Safety Function of servo CPU is not normally executed
Turn the power OFF and ON once.
If the same error recurs, contact the manufacturer.
Note) "(*)": shows the detected model. (the the lower digit of the parameter for the model registry)
A collision avoidance was detected
Release the collision avoidance state

Collision avoidance comm. error
Check the robot controller
A lot of collision avoidance models
Reduce the collision avoidance models
Collision avoidance was already detected
Move the robot arm from the interference area and resume the operation.
An error was detected in the data of tracking encoder.
1) The conveyor rotates at the fixed velocity.
2) The connection of the encoder.
3) The earth of the earth wire.
Tracking parameter[EXCRGM*] Setting value reverses
Check the parameter[EXCRGM*] value.
Tracking parameter[TRBUF] Setting value is range over.
Setting range: element 1=1-8, element 2=1-64
Check the parameter[TRUBF] value.
