Study of Stepper Motor Control using Programmable Logic Controller (PLC) based on Industry 4.0

Stepper motors have found applications in multiple domains of technology. The use of stepper motors in automation and robotic projects is extremely notable; for example, dot matrix or inkjet printers make use of two stepper motors to control positioning, whereas CNC router machines might require around three or four stepper motors for three-axis position control. Basically, stepper motors are helpful in applications where exact positioning of a component or activity is required. Here below, we have discussed the control methods for a stepper motor and investigated in-depth about its control using a programmable logic controller (PLC) and the use of an HMI for interfacing it.
