摘要：In view of the fact that the need of high precision and safe production of multi-axis robot, a real-time coordinate detection method is designed by using virtual instrument software structure VISA. Programmable multi-axes controller (PMAC) is used as the control system of the lower computer, LabVIEW as the upper computer, PMAC board communicates with the upper computer through industrial Ethernet, and sends command data and pulse signal to the servos through the bus. LabVIEW uses VISA software interface to communicate with the servo drivers, uses Modbus protocol to obtain absolute position data, and calculates the current coordinates of the workbench. Experiments show that the multi-axis robot coordinate detection method based on LabVIEW can realize the coordinate detection of the moving platform, and the following error current value can also be displayed in the working interface.
