变频器控制在工业自动化领域有着广泛的应用，其主要目标是控制电机的运行状态。根据目前控制系统的发展趋势，使用 Visual C++的 MFC 类编写串口程序，以 ModBus 为通信协议，经RS-232转 RS-485电路，实现利用上位机对台达变频器 VFD-M 的所有参数进行设置，使对变频器的实时控制成为现实，最终实现面向现场的自动化控制。

Converter control system has been widely used in the automation industry region . The basic function of the convert-er in the system is to control the running state of a motor . According to the current development of control-system , we design to control converters directly by a personal computer . We introduce how to set all kinds of parameters of the Delta converter VFD-M based on the ModBus protocol and the RS-232/485 converting circuit with the usage of the MFC in Visual C++ manipulating the Serials . As a result , we meet the need of real-time control . And further more , we make it possible to manipulate the control on-site automatically .
