Driver input signal interface functionSignal interfacePLSand and PLS- are the positive and negative ends of the control pulse signal DIRand and DIR- are the positive and negative ends of the direction signal ENAand and ENA- are the positive and negative ends of the enable signal. 24V requires a series of 2K resistorsMotor interfaceAand and A- are connected to the positive and negative ends of the A-phase winding of the stepping motor Band and B- are connected to the positive and negative ends of the B-phase winding of the stepping motor. When the A and B phase windings are exchanged, the direction of the motor can be reversed.Power connectorUse DC power supply, the recommended working voltage range is 20-50VDC, the power supply is greater than 100W, according to the actual use, the input is not more than DC40V is a suitable choiceIndicator lightThe drive has two red and green indicator lights. The green light is the power indicator light. When the drive is powered on, the green light is always on the red light is the fault indicator. When there is an overvoltage or overcurrent fault, the fault light is always on. After the fault is cleared, the red light is off. When the drive fails, only re-power on and re-enable to clear the fault.Products include: 1xdrive Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
