Servo positioning by pulse laser cutting machine

Servo positioning by pulse laser cutting machine, and basically can understand it, servo motor to receive a pulse, will rotate one pulse of the corresponding point of view, so as to realize the displacement, because, the function of the servo motor itself has a pulse, so each rotation Angle of a servo motor, send out the corresponding number of pulses, in this way, and the servo motor to accept pulse forming the echo, or closed loop, as a result, the system will know how many pulses sent to the servo motor, how much charge pulse back again at the same time, in this way, can be very precise control of the motor rotation, so as to realize accurate positioning, can reach 0. 001mm。
