  • Page 64. Graphic commands (Graphic command I/F) Graphic commands are instructions for executing animation. CNC outputs these commands to PC. PC reads them and executes animation according to the instructions. Supported graphic commands are as follows. CODE(hex) DATA DESCRIPTION 70 Error status(1byte) erro
