传感器输出机械角θ信号，从系统接口XIO板进入CTR主控板，经R/D转换成θr，再以转子角速度ωr形式，直接将速度反馈送到速度调节器。
转矩给定T_R将来自于速度调节器的SFC_T_R进行转矩限制处理和di/dt运算，求出最终的转矩基准IQ_R信号。ID_R是磁通给定信号，它有以下功能：在基速以下，保持磁通恒定，电机恒转矩调速；基速以上，保持电压恒定，磁通按一定比例减少，电机恒功率调速。
处理器主板在矢量计算控制系统完成IGBT触发信号后，把触发脉冲传送到逆变器，控制IGBT导通和关断，得到所需电机近似于正弦波的输入电压和频率，进而调节电机转速。
2.3数据通信
传动系统和PLC间通信采用FL-NET总线,光纤连接，变频器与HUB之间，以太网通讯。结构见图7。
EN：Ethernet接口模板 I/O：输入输出模板 EGD: Ethernet Global data
FL-NET：FL-NET模板 Switch：开关
PLC系统配置了一块FL612接口模块和一块EGD模块，与各变频器进行数据交换。各变频器地址均在EGD中配置，传动与PLC及传动与传动之间数据交换都是通过EGD来完成。
FL-NET网络以Ethernet为物理层，采用总线拓扑结构，是日本采纳的一种PLC网络标准，其协议栈高层为UDP/IP+ UDP/IP+独自循环通信协议，以保证通信的实时性。
PLC系统与传动系统间数据交换基于EGD(Ethernet Global Data)以太网全局数据处理通信，EGD协议是美国GE自动化公司基于以太网技术的数据交换协议，它以数据报文形式在一个发送者和多个发送者之间实现100Mbps数据高速传送，遵循UDP/IP独自循环通信协议。数据发送时间间隔短，安全性强，不易丢失，各站为双向角色，既是服务器也是客户端。
3. 系统调试
从图5中可以看出，这是一个典型的双闭环控制系统，TMd-10e2提供了多种调试手段，从静态的电机自测试到负荷调试，其目的都是为了确保系统的稳定和快速响应。
3.1 系统转矩优化测试Fully meet the requirements of real-time acquisition and control.
Other PLC fixed communication data storage addresses are inconvenient for application. S7-1200 can define different data addresses for different sub stations.
Some PLC communication instruction packages such as Omron or delta fix the data read by each communication in a specific register. When you want to use it, you can "transfer" it out of this register for use. This always means that when PLC reads different data of the same equipment or different equipment, you must "plan" to "move" the data you need from the public fixed data register "accurately" and "timely" according to different times, otherwise the public fixed data register may be replaced by "new" data refresh, resulting in data confusion. To complete these tasks, you must have good programming habits and write a lot of programs for timing processing. If the amount of data is large, it is definitely a test for an engineer.
S7-1200 is much more flexible in this regard. You can put the data you read into any defined data background data block, which is very easy and simple.
