7CM系统是一种三座标任意两联动具有直线插补和自动过象限的圆弧插补机能的闭环数控装置。其控制部分的核心是采用16位字长的高速微处理器,系统采用直流电机作驱动电机,用旋转变压器或感应同步器作为反馈控制装置。根据需要,还可以增加各种附加机能,形成扩展型系统。 本文仅对7CM系统中位置控制单元作介绍。 一、7CM系统位置控制原理 7CM系统的位置控制器,包括位置控制单元和位置检测单元两部分。它和速度控制单元组成位置控制系统。其示意图如下: 位置检测单元检感旋转变压器(或感应
7CM system is a closed-loop numerical control device of three-coordinate arbitrary two-linkage circular interpolation with linear interpolation and automatic quadrant. The control part of the core is the use of high-speed 16-bit microprocessor word, the system uses DC motor drive motor, with a resolver or induction synchronizer as a feedback control device. According to the need, you can also add a variety of additional functions to form an extended system. This article only describes the position control unit in 7CM system. A, 7CM system position control principle 7CM system position controller, including position control unit and position detection unit in two parts. It and the speed control unit form the position control system. The schematic diagram is as follows: The position detection unit detects the resolver (or induction)
