Abstract
PURPOSE: To detect the same travelling distance by the sum of the same pulse number in counter output, by dividing output pulses into groups consisting of fixed pulse number, and by correcting pulses to frequency.
CONSTITUTION: A generating pulse converting circuit 10 is mounted between a wave-form shaping circuit 41 and counter 42. If the input pulses of 60 Hz is input to the distance detecting counter 42 as a pulse row obtained by omitting one pulse among six pulses of the input pulses, the sum of pulse number extracted by a gate circuit 43 can be set to the same value as 50HZ. Pulse signals proportioned to the number of the revolution of a motor for driving an elevator are counted in spite of the difference of frequency, and travelling distance is detected.
