在应用MCE Designer 跟踪功能调试速度环参数时,由于我们电机额定速度只有340rpm,而跟踪虚拟示波器的X轴量程又不能设置超过512,导致在速度从100rpm加速到额定值340rpm时看不到速度动态变化图形,请问如何解决?

是的,MCEDesigner最大显示为512个采样点,这里可以设置采样时间间隔,如下图,设置采样间隔为最大250个PWM周期,假设PWM频率10k,则每个采样点间隔100us * 250 = 25ms,则最大显示为25ms*512 = 12.8s

Hi,

Are you talking about the scaling the speed range for the monitor trace?
