在驱动器内部的电流环，速度环和位置环（变频器没有该环）都进行了比一般变频更的控制技术和算法运算，在功能上也比传统的伺服强大很多，主要的一点可以进行的位置控制。

通过上位控制器发送的脉冲序列来控制速度和位置（当然也有些伺服内部集成了控制单元或通过总线通讯的方式直接将位置和速度等参数设定在驱动器里），驱动器内部的算法和更的计算以及性能更优良的电子器件使之更于变频器。

可编程逻辑控制器的系统硬件、软件配置及功能应与装置规模和控制要求相适应。熟悉可编程序控制器、功能表图及有关的编程语言有利于缩短编程时间，因此，工程设计选型和估算时，应详细分析工艺过程的特点、控制要求，明确控制任务和范围确定所需的操作和动作，然后根据控制要求，估算输入输出点数、所需存储器容量、确定可编程逻辑控制器的功能、外部设备特性等，后选择有较价格比的可编程逻辑控制器和设计相应的控制系统。

The current ring, speed ring and position ring inside the drive (the frequency converter does not have the ring) are more control technology and algorithm than the general frequency conversion, and are much more powerful than the traditional servo in function, and the main point can be the position control.

The speed and position are controlled by the pulse train sent by the upper controller (of course, some servo internal integrated control unit or directly set the position and speed parameters in the drive through the bus communication), the algorithm and more calculation and better performance of the electronic devices inside the drive make it more than the inverter.

The system hardware, software configuration and function of the programmable logic controller should be adapted to the device scale and control requirements. Familiar with programmable controller, function chart and related programming language is conducive to shortening programming time, therefore, in the selection and estimation of engineering design, the characteristics of the process and control requirements should be analyzed in detail, the control task and scope should be defined to determine the required operations and actions, and then according to the control requirements, Estimate the number of input and output points, the required memory capacity, determine the functions of the programmable logic controller, the characteristics of external devices, etc., and then select the programmable logic controller with a higher price and design the corresponding control system.
