Abstract

PURPOSE:To decrease the loadless running period of driven machine by calculating the loaded running period and the loadless running period of the motor, and giving a motor stopping signal when the result has reached the specified value determined by the rated thermal limit characteristics of the motor. CONSTITUTION:A pulse signal A sent from a clock pulse generator 1 is converted into pulse signal B and C by a frequency dividing circuit 2. The pulse signals B and C are applied to a pulse intergrating circuit 6 via an OR gate 5 depending on the AND condition of a loaded running signal D and a loadless running signal E. A comparator circuit 7 sends out the stopping signal I which stops the motor when the output K of the pulse integrating circuit 6 has reached a motor constant M set in a motor constant setting circuit 8. In this constitution, the loadless running period before stop can be reduced.
