摘　　要：为方便用户对伺服驱动系统的控制与监视,缩短电机调试周期,以Modbus为通信协议,RS232总线连接,设计了一款用于伺服驱动调试的上位机软件。上位机通过向伺服驱动系统发送命令帧实现了对电机的控制,并接受返回帧,完成对下位机的状态显示。实际应用表明,该软件运行稳定、测试准确、人机界面友好,达到设计要求。In order to facilitate the user to control and monitor the servo drive system and shorten the period of motor debugging,a host computer software for servo drive debugging was designed with Modbus as the communication protocol and RS232 bus connection.The control of the motor was realized by upper computer sending the command frame to the servo drive system,and the return frame was accepted to display the status of the lower computer.The actual application shows that the software runs stably,tests accurately,has friendly human-machine interface and achieves the design requirements.
