*1 Based on an acceleration of 0.3 G and the maximum speed.
*2 The maximum speed is assumed.
*3 The table below shows the relationship of acceleration/deceleration and loading capacity.
These values are not guaranteed and should be used only as a guide.
Even when the acceleration is equal to or below the rated acceleration, the loading capacity remains the same
as the value at the rated acceleration.

Caution: x Use each actuator by observing its maximum speed.
x Take note that resonance may still occur at speeds below the applicable limit specified
above, depending on the installation condition or operating conditions.
x Resonance of the ball screw shaft may increase the noise level or cause vibration,
resulting in a shorter service life of the machine.
x If each actuator is used independently, write a program conforming to the maximum
speed of the actuator (refer to the table above). If multiple actuators are used in a
synchronized operation, write a program conforming to the lowest of the maximum
speeds applicable to all synchronized actuators.
x In either way, always check the maximum speed of each applicable actuator when writing
a program.
