Title: Regenerative processing circuit for servo motor
Inventor: SATO KAZUO
IPC: H02P3/18
Filed: 1993-02-22
Abstract: PURPOSE:To prevent burning due to overheat by preventing the flow of an excessive regenerative current to a regenerative resistor or a transistor by suppressing deceleration in such a manner that a regenerative energy value will not exceed an allowable regenerative energy value when the regenerative energy value is larger than the allowable regenerative energy value. CONSTITUTION:A regenerative processing circuit comprises a comparator 1, a regenerative resistor 2, a CPU4, a pulse counter 5, pulse encoder 6 and a transistor 8. The comparator 1 outputs a regenerative current to the regenerative resistor 2 through the transistor 8 when a regenerative voltage generated by the deceleration of a servo motor 7 has entered. If there is a regenerative energy exceeding an allowable regenerative energy when the motor performs regenerative operation, the deceleration of the motor is restricted by a deceleration torque, with which the regenerative energy will not exceed the allowable regenerative energy, thereby prohibiting the flow of a current which exceeds the regenerative resistor 2 and the allowable capacity of transistor 8.

Title: Saw blade slip detecting method for sawing machine and device thereof
Inventor: MORIYA KIKUO
IPC: B23D55/06
Filed: 1989-02-14
Abstract: PURPOSE:To positively and exactly detect the conditions of saw blade slip when the slip of the saw blade is detected by computing the pitch of the saw blade based on the number of saw-teeth for unit time and the saw blade speed, and comparing the period of the pitch of the saw blade with each other. CONSTITUTION:A signal indicating the presence of the teeth of a band saw blade detected by a contactless switch 33 is received by a counter 35, and the counter 35 counts the number of teeth for unit time by means of a timer 37. Further, the travelling speed of the saw blade is stored in a saw blade speed memory 41. From the saw blade speed stored in the memory 41 and the number of teeth of the saw blade for unit time, the pitch of the saw blade is computed by an arithmetic unit 39. Based on the computed pitch of the saw blade, the period of the pitch of the saw blade is compared by a comparator 43. When the saw blade slips, the period of the pitch of the slipped saw blade becomes longer compared with the same period of the pitch of a saw blade not slipped. When the saw blade completely slips, no period is produced, so that comparison of the periods cannot be performed.
