Condition [2]
Thrust for continuous operation
Confirm that the thrust for continuous operation Ft, calculated by considering the load and duty, does not
exceed the rated thrust of the ultra high-thrust actuator throughout the cycle. Here, remember that push
motion operation should not be performed more than once per cycle.
Here, Fa/Fd represents the force required for acceleration/deceleration and changes according to the
operating direction. Calculate the value using the formulas below:
Horizontal application (both acceleration and deceleration)
Accelerate in downward motion in vertical application
Move at a constant speed in downward motion in vertical application
Decelerate in downward motion in vertical application
Accelerate in upward motion in vertical application
Move at a constant speed in upward motion in vertical application
Decelerate in upward motion in vertical application
Stand by in vertical application
*1: If an external guide or other similar component is installed, the traveling resistance must be
considered.
M: Mass of moving part (kg)
m: Loaded mass (kg)
d: Commanded
acceleration/deceleration

)
If the calculated thrust for continuous operation Ft is smaller than the rated thrust, the actuator can be
operated.
Rated thrust of a ultra high-thrust actuator with 2.5 (1t) lead: 5100 N
Rated thrust of a ultra high-thrust actuator with 1.25 (2t) lead: 10200 N
The actuator can be operated under operating conditions where both conditions [1] and [2] are satisfied.
If either condition cannot be satisfied, take an appropriate countermeasure such as decreasing the push-
motion operation time or increasing the standby time to lower the duty.
Mass of moving part: 9 kg
