摘要
详述了用PLC控制步进电机实现数控系统的定位控制功能的方法,新型PLC的高速脉冲输出功能有效的避免了扫描周期的影响,完成快速移动和精密定位。
This paper describes particularly the method with which PLC controls stepping motor to accomplish orientation function in NC system. The new type of PLC is able to output high-speed pulses that can avoid PLC scan cycle impact validly and drives stepping motor to finish orientation.
