Drive technology solutions for multiple engraving machine

at present, the stone carving machine has been slowly into the stone industry. It is convenient and quick, high efficiency. Is indispensable to stone carving enterprise is now on machine tool. Explain the principle of stone carving machine is below? He said that if the work?
ninety percent of the stone carving machine in the market now are using ray racing driver. Below I to simple know about the connection mode and working principle of the driver. Stepper motor is the electrical pulses into angular displacement actuator open-loop control components. Under normal circumstances stop position of the motor depends on the pulse signal frequency and pulse number, stepper drives are used to control the step motor running controller.
from another Angle is to give the motor a pulse signal, motor is turned a step Angle. Drive is to segment the stepping Angle such as to the motor a pulse, motor rotation. Degrees, if use drive to segment, so a pulse to stone motor, the motor will turn. Degrees. That is to say, motor rotation of Min unit is smaller.

P port connection:
PUL electric pulse signal. Step motor rotation, stop, speed control and stop bit high level direction signal inversion DIR. Control of stepping motor rotation direction. Low level forward. Drive under the condition of charged, ENA enable signal. When the high electricity at ordinary times. Motor is not charged, can be arbitrary rotation by hand, is generally used in maintenance and anti-collision.
