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
4243
Improper speed reference was
generated in high power mode.
The robot over speed was detected during
high power mode.
Check the
(Smoothness, backlash, non-smooth
motion, loose belt tension, brake)
Check whether the robot does not
interfere with peripheral equipment.
(Collision, contact)
Replace the motor driver.
Replace the motor. (Motor and encoder

range specified by XYLim during the
Check the XYLim setting.
4252
Coordinate conversion error occurred
during the operation.
Check whether a CP motion trajectory is
within the motion range.
4261
The Arm reached the limit of motion
range in conveyor tracking.
Place the conveyor inside the moiton
range. Meanwhile, allow the tracking
range for the deceleration when switching
from tracking motion to non-tracking.
If error occurs during the shif
t from
tracking motion, it may be prevented by
increasing the accel speed to complete

The Arm reached the limit of pulse
motion range in conveyor tracking.
