应用PLC高速计数功能实现数控机床工作台的控制

Application of PLC High Speed Counter in Numerical Control Machine Tool Worktable

数控机床的驱动性能及位置控制性能是决定机床性能的关键.直流伺服电动机带动机床工作台,通过编码器检测电动机的转速,利用PLC的高速计数功能实现电机转速及机床工作台位移的检测,通过PLC输出脉冲的设定,完成对伺服电动机转速控制,进而实现对工作台的进给控制.

The drive property and location control property are important for numerical control machine. DC servo motor drags tool worktable, coder measures motor speed. The high speed counter and output phase of PLC control motor speed and tool workbench location.
