GT-400 Series Motion Controller


The GT-400 series motion controller is a universal controller developed by Googol Technology. The series has several product versions, including the GT-400-SV, GT-400-SG, GT-400-SP, GT-400-SE and GT-400-SD, widely used in applications ranging from simple point-to-point motion control equipment to highly complicated profile motion control equipment, such as measuring machines, engraving machines, NC lathes, machining centers and robots.



  • Adopt high-performance DSP and FPGA technology
  • servo/step motor controls
  • Sampling period is programmable. The minimum interpolation period of four axes is 200μs. The minimum control period of single-axis motion is 25 μs
  • Motion mode: point-to-point motion, linear interpolation, circular interpolation, velocity control, manual pulse generator interface, and electrical gear. Programmable T-curve planning and S-curve planning. On-the-fly update motion control parameters
  • All the position and parameter registers are of 32 bits
  • Hardware capture home switch and index signal of encoder
  • Set following error limit, acceleration limit and output limit, to ensure safe and reliable control
  • PID (Proportional-Integral-Derivative) digital filters with velocity and acceleration feed-forward, and integral limit and output bias compensation
