Design and Realization of Frequency Divider in Servo Drivers Based on FPGA

A scheme to implement frequency divider in servo drivers is presented.At first,quadruple the input quadrature pulses,then divid frequency,finally,generate quadruple pulses.It′s possible to achieve any integral multiple frequency dividing using this method.Simulation and experiment have been done and the results are given.The feasible of the scheme is proved by the simulation results and experimental results.
