GT-400-SCAN Laser Scanner motion Controller
This motion controllers is developed based on DSP processor and FPGA technology. GT-400-SCAN laser scanner motion controller can control scanner, motors and laser synchronously and effectively. Its is using PCI bus hardware interface and it can provide up to 4-axis pulse output and each motion axis is mutually independent. With larger memory, higher control performance, and more precise control command set, the controller is widely used in the industrial fields such as sophisticated processing, semiconductor incision, high speed forming and laser drilling, etc.

Technical Specification

Motion Control:

  • 4 Pulse/direction or CW/CCW independent output for Step motor or servo motor control
  • Able to realize cylinder and large breadth flat mark
  • 1 MHz maximum step output rate for each axis
  • Programmable LIMIT and ALARM protection
  • Hardware capture signal : INDEX signal of each axis, HOME switch and Probe
  • T curve velocity profile
Scanner Control:
  • Voltage output for scanner control, which consists of 2 axes of linear interpolation and 2 axes of circular interpolation, and three-dimensional dynamic focus function (optional).
  • 10us scanner control cycle
  • Motion buffer can contain up to 10000 motion commands, providing a high real time control capacity
  • Pause, stop and restore for the buffer motion
  • 2 Modes of the mark on fly: mark on the fly without encoder feedback and mark on fly with or without encoder feedback.
  • 3 Modes for the raster images scanning which can scan black-and-white image and grayscale image
  • Field correction algorithm in board
  • Have jump-laser-on function
Laser Control
  • Able to control CO2 and YAG laser sources to give flexible FPK and STANDBY signals
