Abstract
With the rapid development of microprocessors, computer and digital communication technology,the computer control has been extended to almost all the industrial field.Currently the computer control system which has been used in industrial control are mainly about: PLC control system,based on PC bus industrial control system, based on the control system single chip and distributed control system (DCS) and field bus control system (FCS).As the PLC with stable and reliable characteristic , simple structure, low cost, easy to operate, easy to use and powerful, has become the most extensive application in general industrial control equipment and mainstay of the modern industrial automation. Therefore the control of PLC to the stepping motor and servo motor control system has been widely used, and it also has practical value.
In view of this, this design for this content has six stepper motor coordination control,through three S7-200 PLC to control step-motor drive to move up and down and with servo motor control. Mainly about motor control system design, including hardware design and software design,with commissioning and having attention with some matter .
