Abstract
The article presents a numerical control system of a multi-axis machine built using a programmable logic device.The system consists of PC, motor controller (based on FPGA), power stages and motors. The complete code of controller was written in the VHDL language and implementing in Xilinx Spartan 3 board. The PC program was created using LabVIEW.The logical and functional tests of the system have been carried out. The application of a programmable device enables its quick configuration according to the requirements set by the user.The main advantage of FPGA is the option to expand to following modules, such as the incremental encoder support module, PWM, FOC etc. In these applications, the advantage of the programmable system becomes visible, which due to its specifics, is built for parallel processing or generating signals.
