Machines function optimally when the drives are perfectly adapted to the power train. This ensures that a high-quality product is produced at the highest machine cycle rate with a minimum production error rate. To achieve this, the control loop in the inverter is set to be machine-specific. Until now, a drive expert would need several hours to complete this task during the commissioning phase. The time required for this manual setting would depend on the complexity of the motor control loop. But now, this adjustment can be done faster – and better.
High-precision tuning of the control loop in the drive is a basic requirement in many machine applications – e.g., assembly robots, storage and retrieval machines (SRM), packaging machines. This is the only way to achieve competitive machine performance. To achieve this exact tuning, the drive specialist has to invest a lot of time during commissioning. By using the Lenze auto-tuning function, commissioning times have been significantly reduced for Lenze customers in a wide variety of applications.
The physical models commonly used to represent the motor control loop for a machine are only of limited use in practical applications for optimum control loop setting of the drive axis. The reason for this is deviations in the behavior between the physical model of a machine and the real machine. The optimization of the control setting is currently carried out in several tests on the real machine by a drive specialist.
从1943年开始的Ziegler/Nichols振荡法通常用于控制环路优化。此方法易于应用，而不是基于模型，并产生强大的控制结果。
Lenze现在已经自动化了电动机控制回路的测量以及Lenze I系列伺服逆变器的控制环参数的设置，并显着简化了该过程。该方法集成在Lenze自动调节中。除了伺服逆变器外，不需要其他测量组件，因为在自动调整时，驱动器本身就会与位置编码器和电动机电流的实际值一起自动调整。自动调整完成后，计算控制循环参数的设置并存储在驱动器的配置中。现有的物理电动机控制回路会自动迅速测量，并对真实机器进行精确适应。避免了先前由于模型偏差或手动调整期间发生的错误。此过程节省了调试时间，很健壮，可为机器提供可再现的结果和最佳性能。即使有复杂的控制循环挑战，例如“齿轮反弹”或“可变负载”，自动调整功能也可靠地安全。
The Lenze auto-tuning function can be executed with the Lenze tools EASY Starter and PLC Designer. Attention was paid to the simplest operation and feedback so that commissioning engineers, without expert knowledge, can also execute these functions.
Lenze客户的反馈已经在机器中使用了此过程，一直是积极的。特别是，与先前的手动程序相比，简单，健壮的原理和巨大的优化速度被认为是巨大的优势。不仅可以改进机器的周期时间，而且还可以改善机器的输出，这一事实也提供了高度的满意度。
自汉诺威·梅斯（Hannover Messe）2021年以来，自动调整功能就可以使用。自那时以来，所有i950和i700伺服逆变器都可以执行自动调整功能。通过固件更新，可以通过自动调整功能扩展贸易展览会之前出售的设备。
