Problems solved by technology

[0029] (1) When using the industrial Ethernet control method, there is a delay in the information transmission between the control system and the servo driver, which will affect the synchronous control and quick response of the multi-axis control system
[0030] (2) The motion control platform using single-chip microcomputer has relatively few internal integrated circuits, limited data processing capability, and cannot integrate complex peripheral interfaces, so it can only be applied to the application scenario of simple motion control
[0031] (3) Motion controllers using ASIC as the core have poor versatility and customizability, and cannot be compatible with various usage scenarios

Embodiment

[0392] 1. Build the test platform.

[0393] The test platform of the multi-axis motion control system is built. The test platform consists of a safety power supply, a multi-axis motion platform prototype (including the main control board MC), an upper computer PC, a handheld box, and four 80ST-M01330LMB Huada AC servo motors (built-in 17-bit absolute encoder). The prototype is connected with four servo motors through the motor power interface and the encoder interface.

[0394] The hardware test of the motion control platform mainly includes UART serial port, USB 2.0 and Ethernet interface function test. The task communication test of the platform system includes two parts: function realization and performance. Among them, the functional test checks whether the periodic task communication and non-periodic task communication between the dual cores are normally implemented. The performance test verifies the real-time and synchronous control effect of the motion control system...
