[Cause]
The load setting is different from the actual load weight.
[Remedy]
Check whether the load setting is consistent with the actual load weight. Load setting accuracy may be low.
When the external force value exceeds the load weight error limit, the load weight [kg] accuracy may be very low.
Otherwise, either the weight of the load [kg] or the position of the center of gravity of the load may have low accuracy. After seeing the external force value just after switching the load, you can see the approximate error of the load weight [kg].
