The control of pulse quantity is mostly used for angle control,distance control and position control of stepper motor and servo motor.The following takes a stepper motor as an example to describe each control method.

1.Angle control of stepper motor.First of all,it is necessary to clarify the subdivision of the stepper motor,and then determine the total number of pulses required for one revolution of the stepper motor.Calculate”Angle percentage=set angle/360°(ie one circle)””Number of angle action pulses=total number of pulses in one circle*angle percentage.”

The formula is:the number of angle action pulses=the total number of pulses in one circle*(set angle/360°).

2.Distance control of stepper motor.First,determine the total number of pulses required for the stepper motor to make one revolution.Then determine the diameter of the stepper motor roller and calculate the circumference of the roller.Calculate the distance traveled by each pulse.Finally,calculate the number of pulses to run for the set distance.

The formula is:set distance pulse number=set distance/[(roller diameter*3.14)/total number of pulses in one circle]

3.The position control of stepper motor is the synthesis of angle control and distance control.

The above is just a simple analysis of the control method of the stepper motor,which may be different from the actual situation and is only for your reference.

4.The action of the servo motor is the same as that of the stepping motor,but the internal electronic gear ratio of the servo motor and the reduction ratio of the servo motor must be considered.

脉冲量的控制多用于步进电机、伺服电机的角度控制、距离控制、位置控制等。以下是以步进电机为例来说明各控制方式。

1、步进电机的角度控制。首先要明确步进电机的细分数，然后确定步进电机转一圈所需要的总脉冲数。计算“角度百分比=设定角度/360°(即一圈)”“角度动作脉冲数=一圈总脉冲数*角度百分比。”

公式为：角度动作脉冲数=一圈总脉冲数*(设定角度/360°)。

2、步进电机的距离控制。首先明确步进电机转一圈所需要的总脉冲数。然后确定步进电机滚轮直径，计算滚轮周长。计算每一脉冲运行距离。最后计算设定距离所要运行的脉冲数。

公式为：设定距离脉冲数=设定距离/[(滚轮直径*3.14)/一圈总脉冲数]

3、步进电机的位置控制就是角度控制与距离控制的综合。

以上只是简单的分析步进电机的控制方式，可能与实际有出入，仅供各位同仁参考。

4、伺服电机的动作与步进电机的一样，但要考虑伺服电机的内部电子齿轮比与伺服电机的减速比
