Abstract

PURPOSE: To simplify constitution and facilitate arithmetic operations by generating a deceleration start instruction through predetermined arithmetic operations based on a circumference value at an arbitrary time, a stop target circumference value, a circumferential difference per revolution, and a deceleration ratio.
CONSTITUTION: In a circumference measuring unit 3, a length measurement signal fed from a length meter 2 are sampled by a detection signal from a one-revolution detector 1, and the circumference 20 at time t is calculated. A circumferential difference measuring unit 5 calculates the circumferential difference per revolution 24, while a feedback arithmetic unit calculates a feedback value 25 using a stop target circumference 22. A speed measuring unit 4 samples the measurment signals from the meter 2 over a constant time to calculate the speed at time t, while a reference value arithmetic unit 10 calculates a reference value 26 using a deceleration ratio 23. A comparator 8 generates a deceleration instruction when the reference value 6 is equal to or greater than the feedback value 25.
