The GE-300 series motion controllers, developed by Googol Technology, are economical 3-axis DSP-based motion controllers designed for motion control systems that adopt a continuous trajectory motion mode. The velocity invariableness and transition smoothness between any two-trajectory segments during the continuous trajectory motion provide remarkable advantage and result in greatly improved machining precision. The series include the GE-300-SV and GE-300-SG, being widely used in highly complicated profile motion control systems, such as engraving machines, laser cutting machines, laser welding machines, rapid prototyping machines, ultrasonic welding machines, water jet cutters, PCB milling machines, and wafer cutting machines.
