A synchronous motion control system based on SOC is proposed to meet the requirement of flexible set-ting of multi-axis stepper motor transmission ratio and multi-axis synchronization in industrial control field.The multi-axis transmission ratio and spindle motion parameters are set through PC interface,calculated and transmit-ted by ARM software system,received and analyzed by FPGA,and the ladder speed planning algorithm is realized,so as to output multi-axis pulses synchronically.At the same time,the number of multi-axis pulse,pulse delay and velocity curve are determined by logic analyzer.The results show that the system can realize high precision multi-axis synchronous motion control.
