At the same time using Holzer sensors will be converted into pulse frequency motor speed feedback to the MCU, realize the speed closed-loop control, to achieve speed detection.

同时利用霍尔传感器将电机速度转换成脉冲频率反馈到单片机中，实现转速闭环控制，达到转速检测目的。

Anolog speed signal VEL from SDC is also taken as speed feedback signal to form speed loop in gun servo system.

SDC输出的模拟速度信号VEL还可以作为速度反馈信号以构成火炮伺服系统中的速度回路。
