敏感である。特に、短時間内でその周波数が急激にダ化
した場合、脱調などの障害を引き起す。(Prior Art) Due to its characteristics, a pulse motor is sensitive to the signal waveform of a drive pulse. In particular, if the frequency suddenly changes within a short period of time, problems such as step-out may occur.

与えた場合と等価になる。An example of a conventional two-axis interpolation circuit is shown in Figure 2 of the housing. In the figure, the basic pulse P generated by the oscillator 1 is distributed by the distribution setting latches 2 and 6, and the side pulses are set to X=6. When the distribution ratio is set such as Y=5, the X-axis circumferential and Y-axis circumferential drive pulses obtained from the distributor 4 will be as shown in A and B. In other words, the output pulse B will be generated every 6 cycles of the output pulse A. The waveform is one in which one pulse is thinned out, and the ratio of the frequency of the regular pulse train Bs to the frequency of the thinned out pulse B2 is 2:1, which is equivalent to a case where a sudden frequency change is applied.

That is, it is a circuit that converts the data set by the latch 2.3 shown in Fig. 2 into an analog value by a D/A converter, and then generates a pulse train according to this analog value by a Volt-Flifence converter. .

When the frequency division ratio of the frequency division counter is set to Ntl-N=8,
The output waveform is 'IF, as shown in Figure 5. In the figure,
The output waveform immediately after being output from the distributor 4 is Ct = D
Like i, it becomes K. Since the output waveform D1 has a D portion in which one pulse is thinned out every six cycles of the output waveform, the frequency fluctuation rate in this portion is as large as 2:1. However, the waveform of the pulse that has passed through the frequency division counter 5°6 is Ct
