A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.
First, Lab-VIEW software studied by help tool of that. Then, according to the method of stepper motor running (Half stepping, Full step drive and Micro-stepping), this panel designed in order to send differed command to stepper motors. Since these stepper motors connected to CNC mechanical shaft, the panel manipulated to benefit the capability of controlling the speed of CNC and so on.
