Abstract
The 3-axis Motion Control and Amplify Combination System controls and drives most of the brushed and brushless servomotors in industrial manufacturing. The system combines motion control and amplify in high integration module. The system employs DSP and FPGA technologies to support 3 amplifier axes, spanning a variety of voltages and power ranges (12A x 85V). Two digital control loops of outer position loop and inner current loop are designed with frequencies of 4 kHz and 20 kHz respectively. A user-friendly interface allows users to perform controller and motor setting, current and position loop tuning, and diagnosis. The DLL library provides a Visual C++ environment fro the development of various application softwares.

Features
• Integration of high performance motion control and servo amplifier
