Abstract

PURPOSE:To control the number of revolution of the pulse motor arbitrarily by arbitrarily frequency-dividing and outputting input pulses to a pulse rate controller by means of a micro-computer. CONSTITUTION:The output of a pulse generator 2 is inputted to the pulse controller 3. The micro-computer 1 arbitrarily frequency-dividing and outputs the input pulses of the pulse rate controller 3. The output of the pulse controller 3 is inputted to a pulse motor control circuit 4, and the number of revolution of the pulse motor 5 is controlled by the output of the pulse motor control circuit 4.

The output of Com is connected to the so-called 110 circuit, and the software (program) of the microcomputer
By outputting a number of pulses proportional to the number of rotations to the output of T10, the number of pulses to the pulse motor PM is changed to control the number of rotations of the pulse motor. In this method, there is a limit to the processing speed of the microcomputer, so there is a limit to the number of pulses that can be generated in the I/O output.
Therefore, there is a major drawback in that it is impossible to rotate the pulse motor at high speed.

度的にも劣る欠点がある。Therefore, in cases where high-speed rotation is required, the output of the microcomputer μmC0m is sent to a D/A converter (digital-to-analog converter) D via an I/O as shown in Figure 3.
A possible method is to connect this analog output to the V/F converter C shown in Figure 1 to control the rotation speed. However, this method has the drawback that the circuit configuration is complicated, and there are problems with the resolution of the I/A converter and the accuracy is poor.

In the above configuration, the microcomputer 1 can arbitrarily divide the frequency of input pulses to the pulse rate controller and output the divided pulses, so that the number of revolutions of the pulse motor can be controlled as desired.

で精度良く回転数を制御できる。The input pulse to the pulse rate control is given by the pulse generator and can be done at a high speed of 2MH2.Even if the processing speed of the microcomputer is low, it only controls the division ratio, so the pulse motor can be rotated at high speed. can be done. (This division ratio is from ]-/2 to approximately],
/ 4 x 10 g 4, and if the motor responds, it will be as fast as - million pulses/second. ) Also, since the frequency division range is wide, the rotation speed can be controlled accurately from low speed to high speed.
