Abstract

The invention relates to a multi-axial movement controller and its operation based on MPC5200.The movement controller comprises the outside SDRAM, outside FLASH, ERPROM and MPC5200 micro controller connected movement controller critical module, providing the basic environment for software running of the movement controller, going through serial communication interface configuration and top position specific serial communication protocol, connecting it with the top position machine through CAN, RS232, or USB interface for digital controlled data processing and instruction transmission, separating the controller with the top position machine, easy for distributional high performance control, through signal feedback channel and interface to make rectification, counting of the feedback signal of the motor coder, inputting to the MPC5200 micro controller for computation and sending out the result to the pulse driven motor driver through the PWM output interface.

Description

technical field [0001] The invention belongs to the field of automation and advanced manufacturing, and in particular relates to a multi-axis motor motion controller based on an MPC5200 microcontroller and an operating method thereof. Background technique [0002] The motion controller is the core component of the coordinate axis motion control system of the CNC machine tool, and the motion commands of the entire machine tool coordinate axis are given by the motion controller. At present, the main form of motion controller is the motion controller based on PC standard bus. It adopts board design in hardware design, and uses "golden finger" to connect with PC in connection mode, that is, insert board card into PC standard such as ISA or PCI slot, this adopts hard connection structure The motion controller is not suitable for long-term work in harsh industrial sites (vibration, dust, oil, etc.), and because it can only work when inserted into a PC standard slot, the upper com...
