In DDCS System, there is soft algorithm and hard algorithm; hard algorithm is processed by FPGA logic, the movement is very smoothy, and high precise; Soft algorithm is to cut the arc line to a lot of little small pieces. But only when the pulse equivalents of each axis which join into doing the circular interpolation are the same, the hard algorithm can work well; The soft algorithm has no request for pulse equivalents. So when the controller work for helix interpolation, it is better to use soft algorithm.No matter you choose the Soft algorithm or Hard algorithm, it cannot cause the losing step. Losing step must be some other reason. Soft or Hard algorithm only affect the good or bad status of the machinning.
