5. Precautions for Use
(2) CP operations (Use the ACC/DCL instructions of the SEL language for setting.)
z To operate the robot at the maximum acceleration/deceleration, provide a stopping period of three
seconds or more after each acceleration/deceleration.
z Start from the appropriate reference setting for acceleration/deceleration during continuous
operation, and then gradually raise the value for the purpose of adjustment.
z If an overload error occurs, lower the acceleration/deceleration setting as appropriate or provide
an appropriate stopping time following each acceleration/deceleration.
z Depending on the position of the vertical axis, the robot may generate vibration when axis 1, axis
2 or the rotational axis turns. If vibration occurs, lower the acceleration/deceleration as
appropriate.
z To move the robot horizontally at high speed, keep the vertical axis as close as possible to the top
position. If the vertical axis is operated at the bottom position, the spline shaft for the ball screw
will bend and the vertical axis will be disabled.
z Keep the permissible moment of inertia of axis 4 to 0.015 kg˜m or less.
z The carrying load indicates a load above the rotational center of axis 4.
z Operate the robot by using an appropriate acceleration/deceleration coefficient as determined by
the mass of the positioning precision. Failure to do so may cause the drive part to wear
prematurely or may result in damage or vibration.
