The electronic control part of the mechatronics precise positioning device uses a programmable logic controller as the control core to send instructions to change the motor's rotational speed and direction.In order to achieve fast and precise positioning,on the one hand,it is necessary to select the hardware equipment for the electri-cal control part,including programmable logic controllers,stepper motors,servo motors,touch screens,and com-munication optical cables;On the other hand,it is necessary to scientifically allocate the In put/Out put(I/O)ports of programmable logic controllers and design electrical control programs to further improve the effectiveness of pre-cise positioning devices.
