[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)
S6SS, S6SM 15
S8SS, S8SM 25
S8HS, S8HM 35
S10SS, S10SM 65
S10HS, S10HM 80
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.
[Stabilization time tc]
S6SS, S6SM : 0.15 sec
S8SS, S8SM : 0.2 sec
S8HS, S8HM : 0.2 sec
S10SS, S10SM : 0.2 sec
S10HS, S10HM : 0.2 sec
