The invention relates to the technical field of
laser cutting, and specifically relates to a
control system based on multi-axis synchronous movement of an
EtherCAT bus, for a
laser cutting head. The
control system based on the multi-axis synchronous movement of the
EtherCAT bus, for the
laser cutting head is characterized in that a
signal end of an
EtherCAT main
station is bidirectionally connected with a motor driver for the
laser cutting head; a
signal output end of a PD controller is connected with a
signal input end of an EtherCAT communication controller through a communication line; theEtherCAT communication controller is bidirectionally connected with a first main control
board processor through a communication line; the first main control
board processor is bidirectionally connected with a second main control
board processor through a communication line; the second main control board processor is bidirectionally connected with a lens
motor controller through ports separately;and the first main control board processor is bidirectionally connected with a sensor control board through a line port P18. Compared with the prior art, a whole
laser cutting process is dynamically monitored and corresponding key process parameters are collected by virtue of an EtherCAT
bus technology, any manual intervention is not needed, and a spot
diameter size, a focus position and other parameters are automatically adjusted.
