Error message SLS (XYZ Speed Error)
Cause Speed monitor detected the speed over
Measures 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.
H2320 Error message SF robot control error
Cause The robot motion command and the feedback are inconsistent.
Measures 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.
H2370 * One of the errors below is detected.
Please take measures corresponding to an error message.
Error message SF (Process error)
Cause The Safety Function is not normally executed
Measures Turn the power OFF and ON once.
If the same error recurs, contact the manufacturer.
Error message SF (Process Counter error)
Cause The Safety Function of servo CPU is not normally executed
Measures Turn the power OFF and ON once.
If the same error recurs, contact the manufacturer.
L240n
(n: Robot CPU
No.)
Error message Collision avoidance detect (*)
Note) "(*)": shows the detected model. (the the lower digit of the parameter for the model registry)
Cause A collision avoidance was detected
Measures Release the collision avoidance state
L241n
(n: Robot CPU
No.)
Error message Collision avoidance detect (*)
Note) "(*)": shows the detected model. (the the lower digit of the parameter for the model registry)
Cause A collision avoidance was detected
Measures Release the collision avoidance state
L2420 Error message Collision avoidance comm. error
Cause Collision avoidance comm. error
Measures Check the robot controller
L2421 Error message A lot of colli. avoidance models
Cause A lot of collision avoidance models
Measures Reduce the collision avoidance models
L2430 Error message Collision avoidance re-detect
Cause Collision avoidance was already detected
Measures Move the robot arm from the interference area and resume the operation.
L2500 Error message Tracking encoder data error
Cause An error was detected in the data of tracking encoder.
Measures 1) The conveyor rotates at the fixed velocity.
2) The connection of the encoder.
3) The earth of the earth wire.
L2510 Error message Tracking parameter reverses
Cause Tracking parameter[EXCRGM*] Setting value reverses
Measures Check the parameter[EXCRGM*] value.
L2520 Error message Tracking parameter is range over
Cause Tracking parameter[TRBUF] Setting value is range over.
Setting range: element 1=1-8, element 2=1-64
Measures Check the parameter[TRUBF] value.
