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.
