Over speed during low power mode
The robot over speed was detected
Check the robot mechanism.
(Smoothness, backlash, non-smooth
motion, loose belt tension, brake)
Check whether the robot does not
interfere with peripheral equipment.

Improper acceleration reference was
generated.
You attempted to operate the robot with
the acceleration reference exceeding the
specified value.
For a CP motion, decrease the AccelS

Arm reached the limit of motion range
Check whether a CP motion trajectory is
4251
Arm reached the limit of XY motion
range specified by XYLim during the
operation.
Check the XYLim setting.
4252
Coordinate conversion error occurred
during the operation.
Check whether a CP motion trajectory is
within the motion range.
