2.8 Adjusting the clamp/unclamp cylinder speed controllers (M3 double)
Stage 1 – slow-speed clamp/unclamp
1. Refer to the following photo of the clamp/unclamp cylinder speed controllers.
2. Set the volume of each of the lane1 speed controllers as shown in the table below.
3. Disconnect the air supply to the conveyor, and then attach the tube jigs to the lane1
speed controllers as shown in the following photo:
4. Reconnect the air supply to the conveyor.
5. Open the ConveyorTestTool and select the [Transport] tab.
6. Click [Load] and select [Ln1_LoSpeedClmp_chk].
No. M3 Speed Controllers Number of Turns from fully closed

7. Ensure that the lane1 conveyor is unclamped and that the backup plate or the block
jigs (PM24380) are in place.
8. Click [Continuous] to execute the command. The lane1 conveyor will clamp and
unclamp continuously.
9. Adjust speed controller 1 until the clamp response data in the ConveyorTestTool reads
M25.2.
10. Lock the speed controller, and then confirm that the response data still reads M25.2.
11. Wait until the conveyor is unclamped and then press [Cancel] to stop the conveyor
operation.
12. Click [Load] and select [Ln1_LoSpeedUclmp_chk].
13. Ensure that the lane1 conveyor is clamped, and then click [Continuous] to execute the
command. The lane1 conveyor will unclamp and clamp continuously.

14. Adjust speed controller 2 until the unclamp response data in the ConveyorTestTool
reads M25.2.
15. Lock the speed controller, and then confirm that the response data still reads M25.2.
16. Set speed controller 3 to 1.5 turns from fully open.
17. Click [Load] and select [Ln1_INUclmp_chk].
18. Ensure that the lane1 conveyor is clamped, and then click [Continuous] to execute the
command.
19. Adjust speed controller 3 until the unclamp response data in the ConveyorTestTool
reads M25.2.
20. Lock the speed controller, and then confirm that the response data still reads M25.2.
Stage 2 – high-speed clamp/unclamp
1. Disconnect the air supply to the conveyor.
2. Remove the tube jigs from the speed controllers and reconnect the air hoses.
3. Set speed controllers 4 and 5 to 5 turns from fully closed.
4. Click [Load] and select [Ln1_HiSpeedClmp_chk].
5. Ensure that the conveyor is unclamped, and then click [Continuous] to execute the
command.
6. Adjust speed controller 4 until the response data reads M25.2.
7. Lock the speed controller, and then confirm that the response data still reads M25.2.
Unclamp response = M25.2
Clamp response = M25.2
