论述了基于西门子S7-200 PLC控制伺服电机实现高精度灌装定量的方法.PLC中的高速计数器HSC0在第12工作模式中对控制伺服电机的脉冲输出口Q0.0进行高速计数,实现灌装定量的功能.该灌装定量方法具有精度高,稳定性好等优点.%This paper discusses the based on Siemens S7-200 PLC control servo motor to realize high precision filling quantitative method. High speed counter of PLC HSC0 in 12 working mode to control the servo motor Q0.0 pulse output of high speed counter, so as to realize the function of filling the quantitative. The filling quantitative method has high precision, high stability.
