1. Explanation of the procedureA. Simple method:Drva D1000 D1100 Y0 Y4　　　Drva This is the absolute position Control command, D1000 is absolute position designation, D1100 is the pulse output frequency, Y0 pulse output address, Y4 is the direction output, it has two states on and off, if the D1000 is negative, Y4 is off, then if the load is a positive turn, If the D1000 is positive Y4 is on, the load is reversedTwo, detailed Http://wenku.baidu.com/li
