Setting (continue)
Precautions on intermediate position
Intermediate position is set relative to the motor side.
Therefore, if the stroke adjusting unit at the motor side is moved, the intermediate position is
changed.
On the other hand, change of the position of the stroke adjusting unit at stroke does not
make sense.

If the stroke is set shorter than the distance between the motor side and intermediate posi-
tion, the intermediate position is fixed to the center of the stroke automatically.

6.Setting of speed and acceleration
6-1 Setting of speed
By adjustment of switch and , the speed of
actuator is set.
:Rotary switch to set speed of movement to
the direction of the motor side.
:Rotary switch to set speed of movement to
the direction of the end side.
6-2 Setting of acceleration
By adjustment of switch and , the accelera-
tion of actuator is set.
:Rotary switch to set acceleration of move-
ment to the direction of the motor side.
:Rotary switch to set acceleration of move-
ment to the direction of the end side.
