一种带有限位功能的步进电机控制器

A stepper motor controller with function of position limiting

为了适应调焦系统中爬山算法的搜索复位和区域限定要求,对通用步进电机控制器进行了改进,使其可以利用位置感应电路的限位信号主动完成搜索复位和限位。步进电机控制器通过了功能仿真,并在可编程门阵列器件中进行了实验。结果表明该控制器实现了预期的功能要求,复位与限位功能正常。

In order to adapt to the request of search reset and the area limiting of climbing algorithm in focusing system, general stepper motor controller has been improved so that it can be done resetting and limiting using active sensing signal of boundary. The new controller achieved the anticipative function and performance requirement in experiments based on FPGA, the function of resetting and position limiting operates peaceful.
