503-26606-21 DANAHER技术规格

503-26606-21伺服驱动技术作为数控机床、工业机器人及其它产业机械控制的关键技术之一，在国内外普遍受到关注。在20世纪最后10年间，微处理器(特别是数字信号处理器——DSP)技术、电力电子技术、网络技术、控制技术的发展为伺服驱动技术的进一步发展奠定了良好的基础。如果说20世纪80年代是交流伺服驱动技术取代直流伺服驱动技术的话，那么，20世纪90年代则是伺服驱动系统实现全数字化、智能化、网络化的10年。这一点在一些工业发达国家尤为明显。

503-26606-21伺服驱动器按照其控制对象由外到内分为位置环、速度环和电流环，相应伺服驱动器也就可以工作在位置控制模式、速度控制模式和力矩控制模式。 当伺服驱动器工作在任意模式下，其对应 模式可以由三种方式给定：1、使用模拟量给定；2、参数设置的内部给定；3、通讯给定。 参数设置的内部给定应用比较少，为有限的有级调节。

503-26606-21使用模拟量给定的优点是响应快，应用于许多高精度高响应的场合，缺点是存在零漂，给调试带来困难，欧系和美系伺服多采用这种方式。 脉冲控制兼容常用信号方式：CW/CCW（正反向脉冲）、脉冲/方向、A/B相信号。缺点是响应慢，日系和国产伺服多采用这种方式。

503-26606-21我当然最推崇通讯给定的方式，这也是欧系品牌常用的控制方式，优点是给定迅速，响应快，能合理进行运动规划，特别适合凸轮控制和flying定位方式，2012年高档数控机床多采用这种方式。 通讯给定常为总线通讯方式，也有点对点通讯方式和网络通讯方式。

03-26606-21 Servo drive technology, as one of the key technologies in the control of CNC machine tools, industrial robots and other industrial machinery, has received widespread attention at home and abroad. In the last decade of the 20th century, the development of microprocessor (especially digital signal processor-DSP) technology, power electronics technology, network technology and control technology laid a good foundation for the further development of servo drive technology. If the AC servo drive technology replaced the DC servo drive technology in 1980s, then the 1990s will be a decade when the servo drive system will be fully digitized, intelligent and networked. This is particularly evident in some industrialized countries.

03-26606-21 Servo drivers are divided into position loop, speed loop and current loop according to their control objects from outside to inside, and the corresponding servo drivers can work in position control mode, speed control mode and torque control mode. When the servo driver works in any mode, its corresponding mode can be given in three ways: 1. Give it by analog quantity; 2. Internal setting of parameters; 3. Communication is given. There are few internal given applications for setting parameters, which are limited step-by-step adjustments.

53-26606-21 Using analog quantity has the advantage of fast response, and it is applied to many high-precision and high-response occasions. The disadvantage is that there is zero drift, which brings difficulties to debugging. This method is mostly used in European and American servos. Pulse control is compatible with common signal modes: CW/CCW (forward and reverse pulse), pulse/direction, A/B phase signal. The disadvantage is the slow response, which is often used by Japanese and domestic servos.

03-26606-21 Of course, I most admire the given way of communication, which is also a commonly used control way of European brands. Its advantages are quick given, quick response, and reasonable motion planning. It is especially suitable for cam control and flying positioning. In 2012, high-grade CNC machine tools mostly used this way. Communication is usually bus communication, point-to-point communication and network communication.
