[2] Condition 2 Judgment of Thrust for Continuous Operation
It is necessary that the continuous operational thrust Ft considering the load and duty is
smaller than the rated thrust.
Fa : Thrust required for acceleration (N)
ta : Acceleration time (sec)
td : Deceleration time (sec)
Ff : Traveling resistance (N)
tf : Moving time at constant speed (sec)
t : Operation time per cycle (sec) (t = ta + tf + td + 0.15)
Here, Fd indicates the thrust required for deceleration and can be calculated as follows:
Fd = (M +m) • d – Ff
M : Slider weight (kg)
m : Slider payload (kg)
d : Commanded deceleration (m/s 2 )
Ff : Traveling resistance (N)
Condition 2 is satisfied if the continuous operational thrust Ft figured out as described above is
smaller than the rated thrust.
Rated thrust (N)
H8SS, H8SM 30
H8HS, H8HM 60
L15SS, L15SM 30
The actuator can be used in any operating conditions that satisfy both conditions 1 and 2
specified above.
If either condition cannot be satisfied, take appropriate measures such as reducing the slider
load, acceleration or duty.
