*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.
As for actuator types with mid-support, the maximum acceleration is the same as the rated acceleration.
Accordingly, the loading capacity at the maximum acceleration corresponds to the loading capacity 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.
