摘　　要：介绍了立式双动液压机的电控系统应用高速计数器和多预置计数器的两种方案,通过分 析两种方案的硬件组成、程序的控制思想及其适用性,论证了应用多预置计数器是立式双动液压机的 一种设计改进方案。This paper described two electric control systems of vertical double - acting hydraulic- press, one with a high - speed counter, and the other with a initialize counter. Through comparation of the hard-ware, the program control concept and the applicability, it shows that applying initialize counter is an improve - desing for vertical double - acting hydraulic - presser.
