Motion controller

The invention discloses a motion controller which comprises a Core board, an MC board and a power supply module, wherein the Core board is mounted on the MC board in an insertion manner. The power supply module supplies corresponding voltages to the Core board and the MC board. The Core board comprises an ARM process, a memory module, a storage module and a data exchange module. The MC board comprises an FPGA, a DA module, a motor driving module and a signal input/output module. The motion controller aims at requirements of specific devices in different industrial fields. Only adjustment on the hardware of the MC board is required, and adjustment on the hardware of the Core board is not required. A development period of a product is shortened. Furthermore the ARM processor is utilized on the Core board. Because the ARM has peripheral resources such as USB, serial ports and network ports, outer expansion of a corresponding interface chip is not required, thereby simplifying hardware design and improving system hardware reliability.
