高分辨率大幅面彩色静电绘图机可以采用不同的速度绘制图纸，所以主控制器必须要根据不同的速度设定进行不同的处理。首先提出了速度控制的必要性，然后根据设计要求给出了解决方法。这种方法的特点是简单，成本低，并且抗干扰能力强。这种方法稍加改变就可应用于其它速度控制系统中。 High-resolution large format color electrostatic plotter can draw drawings with different speeds, so the main controller must be set according to different speed for different processing. First of all, the necessity of speed control is put forward, and then the solution is given according to the design requirements. This method is characterized by simple, low cost, and anti-interference ability. This method can be applied to other speed control systems with slight changes.
