为什么将智能驱动器与晶圆机的集成运动控制一起使用？

2021年10月5日，星期二

运动控制在传统上是具有精确位置，速度和加速控制的代名词。通常，此类应用需要复杂的伺服解决方案或交流驱动器以及额外的运动控制组件和编码器。借助集成运动控制器（IMC）功能，Danfoss为伺服运动控制提供了有吸引力的替代方案。IMC直接集成到VLT®自动化驱动器系列中，非常容易地执行和不使用编码器的定位和同步任务。在下奥地利的Leobendorf的BühlerGroup晶圆机厂，技术人员已经欣赏了这些优势，尤其是由此产生的运动独立性。

世界知名的国内机器生产系统生产系统的制造商，用于晶圆，饼干和糖果的生产系统已经使用了Danfoss的VLT®驱动器以其前公司的名字FHW Franz Haas Waffelmaschinen多年 - 即使在这一传统的领导下，也仍然忠于这一传统。布勒集团。由于越来越需要同步和位置，机器驱动器最近逐渐转换为伺服技术。

当Danfoss在2017年启动集成运动控制（IMC）功能时，Haas（当时已知）询问新的控制技术是否也是其机器伺服控制的实用替代方法。从相关的自由选择，技术独立性和通过自动电动机适应的简单系统优化的相关自由选择中，特别是优势

IMC提供三种类型的定位

IMC提供三种类型的定位

IMC函数可以普遍使用，因为它可以绝对，相对和传感器定位。在绝对位置，位置引用是指定的机器零点。这是通过所谓的Housing Run在机器开头确定的。如果使用具有绝对位置的可选反馈系统，则无需这是必需的，因为零点是由编码器设置的。在Leobendorf中的典型应用是线性轴绝对定位的锥烤箱的“下游”。这里的任务是将纸放在连续移动的糖果锥的前面，以便能够在下一步中相互滑入。使用的电动机是以开放循环操作的PM电动机。IMC的优点：可以消除旋转编码器，从而消除编码器的成本以及电缆，评估和安装和调试的工作时间。VLT®自动化驱动器（与IMC）本身的使用也可以节省，因为与相应的伺服系统相比，标准驱动器的购买和安装成本明显降低。

同步变得容易

同步变得容易

同步意味着创建两个或多个轴的角同步同步。可以连续调节两个轴的齿轮比。位置和速度的参考信号要么由PLC作为脉冲信号生成的外部编码器拾取，要么通过虚拟主信号指定。该虚拟主信号是一个脉冲信号，可以从中得出旋转，速度和位置的方向。

主驱动器的引用要么通过模拟信号以传统方式进行，要么通过fieldbus上的设定点进行。然后，此主驱动器将信号转换为虚拟主信号，该信号可作为追随者驱动器以及主本身的参考值。

Leobendorf Wafer Machine专家使用与主信号的同步，例如在圆锥烤箱的追随者驱动器中。在随后的过程中，每个轴最多八个轴相互同步。来自PLC的脉冲信号用作主信号。在启动驱动器之前，所有这些都将移至参考位置（归乡）。通过具有不同的变速箱和不同的电动机，通过齿轮比的精确调节，带有变速箱的开路中使用的PM电动机实现了角度同步同步。这消除了对八个轴和伺服控制器的完整编码系统的需求。此外，烤箱可以更快地启动，并且已经简化了工程学体育投注必威

高可靠性以较低的成本

除了简单的参数化外，IMC还提供了高度可靠性，这要归功于经过证明的AC驱动技术和故障时轻松进行故障排除。通常可以由操作员进行推荐，不需要经过特殊培训的人员。集成的运动控制器通过较少的组件以及减少停机时间来降低OEM和用户的成本。体育投注必威
