In the process of constant amount subdividing, the supply method by the intermission drive on vibratory transportation machine is used. By Velocity FB control, a high-speed intermittent drive and high-speed fixed-quantity supply can be done. The authors developed the open loop control that imitated velocity FB control, and the high-speed intermittence drive was done without using a sensor. When a natural frequency is corresponding to natural frequency of open loop control, it shows the characteristic completely equivalent to velocity FB control. However, since open loop control was weakness in the change of natural frequency, the tolerance level of change of natural frequency was investigated. The range was -1% to +0.2% and it was shown clearly that a fixed quantity could be supplied to 210g equivalent to 15% of the mass of a table of transportation machine.
