1.3.2 Availability Judgment for each Operational Condition
[1] Condition 1 Judgment of Thrust Necessary for Acceleration
For the slider to accelerate according to a command, the thrust required for acceleration, or Fa,
must be smaller than the maximum thrust.
Fa = (M + m) • a + Ft
Here,
M : Slider weight (kg)
m : Slider payload (kg)
a : Commanded acceleration (m/s 2 )* *1G = 9.8 m/s 2
Ff : Traveling resistance (N)
In the case of a linear servo actuator (small type / flat type), the traveling resistance is
determined by the speed and empirically calculated as specified below.
[Traveling resistance]
The table below lists the traveling resistance of each model.
Ff = 2V + 10 V: Slider speed (m/s)
(Achieved speed is used in a triangle wave operation.)
If the obtained Fa is smaller than the maximum thrust of the linear servo actuator (small type /
flat type), condition 1 is satisfied.
