  GE series 8--axis motion controllers developed by Googol Technology Ltd is a low cost 8-axis DSP based motion controller, specially designed for point-to-point motion control. Owing to its capability of perfect positioning and velocity profile curves, it is used for quick and accurate positioning applications, and suitable for the equipments that adopt high-speed and high-precision point-to-point motion modes, such as PCB drilling machine, SMT, Bonding machine, etc.
Main Features
