How does the PLC drive the stepper motor?
General PLC drive stepper when two signals, one is angle pulse, another way is the direction of the pulse, PLC inside the so-called general displacement instructions, send trapezoidal pulse to a stepper drive, so you can start to bring the impact of buffer.
Corresponds to a certain pulse stepper motor, corresponding to a certain rotation angle. The PLC can also emit pulses, but the pulse voltage is not enough, so the PLC output pulse is required to be amplified by the step driver to drive the stepper driver, which is equivalent to the pulse of PLC, which is the command pulse.
Stepper motor is to receive the stepper driver to the pulse signal, such as two phase stepper, AB phase, respectively, rotate the output positive and negative pulse (in a certain order), stepper motor can run,
