10	0.007	0.2 to 1.0
20	0.025
30	0.048
50	0.081

*If operated where the kinetic energy exceeds the allowable value, this may cause damage to the internal parts and result in product failure. Please pay special attention to the kinetic energy levels when designing, adjusting and during operation to avoid exceeding the allowable limit.

*Values above do not include auto switch weight.

Piping and speed control method

1.Use one 3-position pressure center solenoid valve or two 3-port solenoid valves. (Figure 1 or Figure 2)
2.Meter-out speed controllers are used for A and B ports and meter-in speed controllers for C and D ports. (Figure 1 and 2 show a state in which the B and D ports are pressurized. )
3.Figure 3 shows the details of each operation, and Table 1 shows the pressure port and speed controller for speed adjustment in each operation.

Figure 1: One 3-position pressure center solenoid valve

Figure 2: Two 3-port solenoid valves

* The return position of the table when the power supply is cut off differs depending on the solenoid valve used. Refer to the manufacturer's catalog for details.

Angle adjustment method

1) For this product, adjust each stop position with the adjust bolt leveling mount shown in Fig. 4.

1.Adjust bolt leveling mounts a and b are for adjusting the swing end, and adjust bolt leveling mounts c and d are for adjusting the intermediate position.
2.Figure 5 shows the angle adjustment range for each adjust bolt leveling mount.

2) Adjust the angle by supplying air to the product. (Low pressure of approximately 0.2 MPa recommended)

1.First, adjust the positions of both ends of the swing.
・ Adjust the adjust bolt leveling mount b by pressurizing the A and C ports
・ Adjust the adjust bolt leveling mount a by pressing the B and D ports
After adjustment, lock with the fixing nut.
2.Next, pressurize all ports A to D to adjust the intermediate position.
・ Loosen the fixing nuts of the adjust bolt leveling mounts c and d.
・ Tighten the adjust bolt leveling mounts c and d to the full extent. (The table can be turned manually. )
・ According to Table 2, operate the corresponding R or L according to the procedure from 1 to 5.

-	R: When adjusting in the clockwise direction	L: When adjusting in the counterclockwise direction
1	Manually move the table counterclockwise until resistance increases.	Manually move the table clockwise until resistance increases.
2	When the adjust bolt leveling mount d is loosened, the table moves clockwise, so set it at the desired position.	When the adjust bolt leveling mount c is loosened, the table moves counterclockwise, so set it to the desired position.
3	Loosen the adjust bolt leveling mount c until the resistance increases. (Make sure that the table has no looseness)	Loosen the adjust bolt leveling mount d until the resistance increases. (Make sure that the table has no looseness)
4	Tighten both adjust bolt leveling mounts c and d by approx. 45°. *1)	Tighten both adjust bolt leveling mounts c and d by approx. 45°. *1)
5	Lock the adjust bolt leveling mounts c and d with the fixing nut. *2)	Lock the adjust bolt leveling mounts c and d with the fixing nut. *2)

*1) When tightening the fixing nut, the position of the adjust bolt leveling mount changes by the clearance of the thread, so tighten the change in advance.
*2) If the table has looseness after tightening the nut, readjust it.

Adjustment angle per rotation of angle adjustment screw

Size	Adjust bolt leveling mount a, b (For edge position adjustment)	Adjust bolt leveling mount c, d (For intermediate position adjustment)
10	10.2°	5.1°
20	9.0°	3.6°
30	8.2°	3.3°
50	8.2°	4.1°

* Instructions for piping, speed control method, and angle adjustment method are included in the product.

Notes

Product Mounting Direction

There are no restrictions to the mounting direction of the product, but if the gravity acting on the load acts in the rotating direction of the table (for example, when the rotary shaft is horizontal and the center of gravity of the load does not match the rotation center), the rotational speed will become unstable.
In particular, the speed from the end position to the intermediate position is controlled by meter-in. Therefore, if this operation direction matches the direction of gravity, acceleration due to gravity cannot be suppressed and bouncing may occur when stopped.

On the Play of the Table in the Middle Position

By properly adjusting the intermediate position, play in the rotation direction of the table can be suppressed. However, as the number of movements increases, play (approx. 0.1°) may occur, so if there is a problem in use, readjust the intermediate position again.

*See the manufacturer's catalog for product information other than the above.
*The product image is a representative image only.
