The invention relates to the field of pulse counters or frequency dividers composed of counting chains, in particular to a servo drive pulse output frequency divider and a using method thereof. The frequency divider comprises a servo motor (11) and an upper computer (12), and is characterized in that the frequency divider also comprises a setting module (1), a quotient accumulator (2), a remainderaccumulator (3), a quotient control logic device (4) and a remainder control logic device (5); the quotient accumulator (2) is connected with the quotient control logic device (4) through a signal line; the remainder accumulator (3) is connected with the remainder control logic device (5) through a signal line, and the quotient control logic device (4) and the remainder control logic device (5) are connected with the upper computer (12) through signal lines. The using method of the servo drive pulse output frequency divider is characterized by being implemented according to the following sequence: (1) accumulation; 2, judging. The device is simple in structure, convenient to use, stable in signal and wide in application range.

Description

technical field [0001] The invention relates to the field of pulse counters or frequency dividers composed of counting chains, in particular to a servo-driven pulse output frequency divider and a use method thereof. Background technique [0002] In the servo drive system, the upper computer needs to monitor the running state of the servo motor, usually in the form of quadrature pulses to output feedback servo motor encoder information through frequency division, the number of quadrature pulses represents position information, and the rate of quadrature pulses represents Velocity information and direction information are represented in the form of quadrature pulses. Due to the requirements of process control, the speed of the motor is constantly changing and the direction is frequently switched. The frequency division output must reflect the change of the motor state in real time and the number of pulses cannot be lost. Conventional frequency division output has the problem ...
