4.4 Precautions for Auto Acceleration/Deceleration of Joint #3
When you move the Manipulator in horizontal PTP motion with Joint #3 (Z) at a high
position, the motion time will be faster.
When Joint #3 gets below a certain point, then auto acceleration/deceleration is used to
reduce acceleration/deceleration. (Refer to the figure below.) The higher the position
of the shaft is, the faster the motion acceleration/deceleration is. However, it takes more
time to move Joint #3 up and down. Adjust the position of Joint #3 for the Manipulator
motion after considering the relation between the current position and the destination
position.
The upper limit of Joint #3 during horizontal motion using Jump command can be set by
the LimZ command.

When moving the Manipulator horizontally while the shaft is being lowered, it may cause
over-shoot at the time of final positioning.
