GE-300 Series Motion Controller



Googol's GE 300 Series motion controllers deliver precise, Three-axis DSP based control in a low-cost package, it was designed for motion control equipments that adopt continuous trajectory motion mode. The velocity invariableness and transition smoothness between any two-trajectory segments during the continuous trajectory motion are their most remarkable advantages, and therefore the smoothness of the machining surface and machining precision can be greatly improved. This series are widely used in highly complicated profile motion control equipments, such as engraving machines, laser cutting machine, laser welding machine, ultrasonic welding machine, water jet cutter, PCB milling machine, and wafer cutting machine, etc.
