Suggestion 1: look at your photos. Do you want to use the servo motor to complete the rotation? Since the belt conveyor can complete the start-up acceleration process, why not complete the deceleration and stop process? Why external braking?

　　问:在这里找到也很有必要。上本体较重，减速机有间隙。

　　Q: it's also necessary to find it here. The upper body is heavy and the reducer has clearance.

　　提示2:定位很简单。当带式输送机旋转到位后，可以重新校准两个螺栓。我不知道你的角度误差有多高也不知道你用的减速器有多高。如果是行星减速机，间隙只有几个角度。与其将组织的资金完全增加到可接受的水平，不如购买一个更好的减速器。或者您可以选择立即添加一个外部旋转编码器。

　　Tip 2: positioning is simple. When the belt conveyor is rotated into place, the two bolts can be recalibrated. I don't know how high your angle error is or how high your reducer is. In case of planetary reducer, the clearance is only a few angles. Instead of increasing the organization's funding to an acceptable level, it's better to buy a better reducer. Or you can choose to add an external rotary encoder now.

　　建议3:安装用于二次定位的钢瓶。

　　Recommendation 3: install the cylinder for secondary positioning.

　　建议4:带式输送机回转运动中常用的制动方式有两种。，作用部分与从动部分的连接(连接部分与从动部分为半刚性)。二是直接制动。我想知道这个建议对你是否有效。

　　Suggestion 4: there are two commonly used braking methods in rotary motion of belt conveyor. First, the action part is connected with the driven part (the connection part and the driven part are semi-rigid). Second, direct braking. I'd like to know if this suggestion works for you.

　　提示5:我们在这方面做了很多工作。它是由DD电机直接驱动的。精度很高，但成本太高。后来改为行星减速加伺服。会有轻微的角度偏差，但还是可以接受的。

　　Tip 5: we have done a lot of work in this area. It is directly driven by DD motor. The accuracy is high, but the cost is too high. Later it was changed to planetary deceleration plus servo. There will be slight angle deviation, but it is acceptable.

　　问:如何减小转动惯量?旋转轴重量80KG，旋转半径600MM。

　　How to reduce the moment of inertia? The weight of the rotating shaft is 80kg and the rotating radius is 600mm.

　　建议6:增加鼓式制动器会影响伺服电机的使用寿命。建议不要使用180度选项轻松地编写启动和删除进程来实现不同的缓冲机制。

　　Recommendation 6: increasing the drum brake will affect the service life of the servo motor. It is not recommended to use the 180 degree option to easily write start and delete processes to implement different buffering mechanisms.
