PMAC2-VME  运动控制器  方便用户进行开发和调试

PMAC2-VME是Delta Tau品牌的产品。

Delta Tau是一家专门从事运动控制系统的设计和制造的公司，其产品广泛应用于各种工业领域。PMAC2-VME是一种紧凑型、模块化的运动控制器，可以用于各种需要高精度运动控制的应用场景。它采用Intel Atom处理器和DDR3内存，支持多种编程语言和操作系统，方便用户进行开发和调试。

控制器是按照预定顺序改变主电路或控制电路的接线和改变电路中电阻值来控制电动机的启动、调速、制动和反向的主令装置。

控制器的组成：PMAC2-VME由程序计数器、指令寄存器、指令译码器、时序产生器和操作控制器组成，它是发布命令的“决策机构”，即完成协调和指挥整个计算机系统的操作。

控制器的作用：PMAC2-VME主要控制电机的转速，同时兼有多种保护功能，如欠压保护、限流保护、刹车断电等。

控制器的基本功能是从主存中取出一条指令，并指出下一条指令在主存中的位置；对指令进行译码或测试，产生相应的操作控制信号，以便启动规定的动作；PMAC2-VME指挥并控制CPU、主存、输入和输出设备之间的数据流动方向。

PMAC2-VME控制器的工作原理是根据指令的要求，当前的时序及外部和内部的状态，按时间的顺序发送一系列微操作控制信号。

控制器根据产生微操作控制信号的方式不同，可分为硬布线控制器和微程序控制器。

PMAC2-VME is a product of the Delta Tau brand.

Delta Tau is a company specializing in the design and manufacture of motion control systems, whose products are used in a wide range of industrial fields. The PMAC2-VME is a compact, modular motion controller that can be used in a variety of applications requiring high-precision motion control. It uses an Intel Atom processor and DDR3 memory, supports multiple programming languages and operating systems, and is easy for users to develop and debug.

The controller is a master device that changes the wiring of the main circuit or control circuit and changes the resistance value in the circuit to control the start, speed regulation, braking and reverse of the motor in accordance with the predetermined sequence.

The composition of the controller: PMAC2-VME is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller, which is a "decision-making mechanism" for issuing commands, that is, to complete the coordination and command of the operation of the entire computer system.

The function of the controller: PMAC2-VME mainly controls the speed of the motor, and has a variety of protection functions, such as undervoltage protection, current limiting protection, brake power off, etc.

The basic function of the controller is to take out an instruction from main memory and point out the position of the next instruction in main memory. Decode or test instructions to generate corresponding operational control signals in order to initiate specified actions; The PMAC2-VME directs and controls the direction of data flow between the CPU, main memory, input and output devices.

The working principle of the PMAC2-VME controller is to send a series of microoperating control signals in the order of time according to the requirements of the instruction, the current timing and the external and internal states.

The controller can be divided into hardwired controller and microprogrammed controller according to the way of generating microoperating control signal.
