In constant ambient temperature.
Tool flange specifications (optional) apply to the YK350TW (4kg) and the YK500TW (4kg)
When moving a 1kg load back and forth 30 mm horizontally and 25 mm vertically (rough positioning arch motion).
May need to limit parameters (such as acceleration) according to the moment of inertia being used.
The recommended positional relationship regarding the center of the load weight (center of gravity position) and the offset amount from the R-axis center are shown in the graph below.
