7. Selection Conditions
When using a mid-size linear servo actuator, you must ensure that the actuator satisfies the following two
conditions.
Condition [1] The thrust required for acceleration must not exceed the maximum thrust of the mid-size
linear servo actuator.
Condition [2] The thrust during continuous operation must be the rated thrust of the mid-size linear
servo actuator.
The above conditions are explained by using a trapezoid
operation as an example.
The above operation pattern can be expressed differently
in a graph where the vertical axis represents thrust.
t: Operation time per cycle (sec)
ta: Acceleration time (sec)
tf: Moving time at constant speed (sec)
td: Deceleration time (sec)
tc: Stabilization time (0.15 sec)
Fa: Thrust required for acceleration (N)
Ff: Traveling resistance (N)
Fd: Thrust required for deceleration (N)
