HENGSTLER RS53 sine?cosine encoder was selected, in combination with 13?bit sine wave signal interpolation subdi?vision chip iC?NQI and the HEIDENHAIN ND281B digital readouts, a high precision AC servo drive and control experimental platform was built. The initialization registers of iC?NQI chip were configured by using serial BISS communication protocol, which was accom?plished by FPGA and VHDL. The current speed, absolute angle and position value of sine?cosine encoder could be digital read real?time. Experimental results show that iC?NQI devices can run smoothly with reliable performance, its positioning accuracy can reach 0?005° ( 18") , repositioning accuracy can reach 0?001° ( 3?6") , the requirements of high resolution, high dynamic performance of servo motor control are met. It has important practical application values in industries with high accuracy, high speed CNC machining systems.
