L6470H速度相关参数的关系

问答对人有帮助，内容完整，我也想知道答案 0 嗨，我在项目中使用L6470H和STM32f103过去几个月。我通过在线阐明了与电机的KVAL值关系。我制定了数据表中给出的所有电机运行命令。它工作正常。电机模式no是：电机数据表链接： http://bholanath.in/certificates ... 57SH56-2804A-ID.pdf 我的问题是在我需要澄清与速度相关的一些事情之前升级我的项目。我试图找出答案，但我找不到合适的答案。我的问题是：在数据表中，有不同的速度参数，如。这些参数是否存在任何一对一的关系。我没有完全澄清这些参数。所以，请指导我弄清楚这些参数是否有步骤值输入这两个参数（）与。在命令中，我已通过步骤值通过MinSpd（）和Speed（）参数电机工作正常。但是，一旦我通过MaxSpd输入速度值并且IntSpd电机没有运行。那有什么特别的原因吗？电机的关系是什么？在dSPIN库代码中，参数中提到的值是否有任何特定的公式来查找这些值？为什么因为这样，我根据数据表中给出的最大值更改了这些参数中的值，但是电机在更改值中运行时遇到了麻烦。所以请有人帮我解决这个问题.dSPIN库代码链接： http://www.st.com/en/embedded-software/stsw-spin004.html 以上来自于谷歌翻译以下为原文 Hi, I am using L6470H with stm32f103 for past few months in our project. I have clarified the KVAL value relation with motor through online.I worked out all the commands for motor running given in the datasheets. It's working fine. The motor mode no is: Motor Datasheet Link: http://bholanath.in/certificates ... 57SH56-2804A-ID.pdf My questions here is to upgrade my project , before I need to clarify few things related to speed. I tried to find out but I couldn't find the proper answer. My questions are: In datasheet, there are different speed parameters like . Is there any one to one relations with these parameters. I do not have complete clarification with these parameters. So, Please guide me to get clarify these parameters Is there any relation between steps value entering in these two parameters( ) with . In the command, I have passed the steps values in through MinSpd() and Speed() parameters motor is working fine. But , Once I entered the speed values through MaxSpd and IntSpd motor is not running.Is there any particular reason for that? What is the relation of for motor? In the dSPIN library code, the values mentioned in the parameters like is there any particular formula to find those values? why because is that , I have changed the values in these parameters based on the maximum value given in the datasheet but motor having trouble to run in changed values. So please someone help me out to overcome this issue. The dSPIN library code link: http://www.st.com/en/embedded-software/stsw-spin004.html 0

答案对人有帮助，有参考价值 0 参数指的是系统的两个不同块。链接到“运动引擎”，即负责产生速度曲线的设备部分。应根据应用的机制调整这些参数。允许在微步进和全步之间自动切换，我建议将其设置为最大值，以强制设备始终以微步进模式工作。是电压模式补偿算法的一部分，取决于电机特性。这些是转换以[step / s]表示的值的库函数（全步，无微步。系统负责内部微步分辨率）和相应的寄存器值（MAX_SPEED，MIN_SPEED等）。电压模式算法可能未正确调整。使用SPINFamily软件估计配置参数。重要提示：在电机轴上施加一个小负载;这将有助于抑制共振。参见第1点和第3点您可以使用SPINFamily工具设置所有这些配置以上来自于谷歌翻译以下为原文 The parameters refers to two different blocks of the system. are linked to the 'motion engine', i.e. the part of the device in charge of generating the speed profile. These parameters should be adjusted according to the mechanics of your application. allows automatic switching between microstepping and full-step, I suggest to set it to the max in order to force the device always working in microstepping mode. is a part of the Voltage Mode compensation algorithm and depends on motor characteristics. These are the library functions converting values expressed in [step/s] (full-steps, no microsteps. The system takes care of the internal microstepping resolution) and the respective register value (MAX_SPEED, MIN_SPEED, etc). The Voltage Mode algorithm probably is not tuned properly. Use the SPINFamily software to estimate the configuration parameters. IMPORTANT: put a small load on the motor shaft; this will help damping the resonances. See points 1 and 3 You can use the SPINFamily tool to set all these configurations
