Caution: Caution at S-shaped Motion
● Since it requires a speed change during the operation, even if having the position
command or direct command that S-shaped motion is set while the actuator is moving,
S-shaped motion control cannot be performed and will be the trapezoid control.
Make sure to make a command while the actuator is stopped.
● S-shaped motion control is invalid in the index mode of the rotary actuator. It will be the
trapezoid control even if S-shaped motion control is indicated.
● Do not use S-shaped motion control if the setting of the acceleration time or the
deceleration time exceeds 2s. It will not provide the right operation.
● Do not pause on the move during acceleration or deceleration. It will change the speed
(acceleration) and may cause a danger.
