Item Type: Input Voltage: DC 12-48V Input Input: 1-5A Current, Select Drive Stepper Motor Output Current: 0.2A-5A Temperature Operating Temperature: -10-45; Storage Temperature -40 -70 Humidity: No Condensation, No Drop Gas prohibits combustible gas and conductive dust Set the Number of Steps Per Motor Step for the Motor 200(synchronizing), 400 (2 segments), 1600 (8 segments), and 3200 Steps (16 segments). Power Interface: 1. DC and, DC-: Connect the drive power DC and: DC Power Supply Level, Power Supply Voltage Dc 12 To 48v, Maximum Current 5a DC-: DC Power Supply Negative Level. 2. A and A-B and B-: Connecting Two-Phase Hybrid Stepping Motor The connection between the driver and the two-phase hybrid stepping motor and the four-wire system, the parallel and series connection of the motor windings, and the connection method, the high-speed performance is high, but the driving current is large (the motor winding current is 1.73 times), when the driving current is equal series connection when the motor winding current Troubleshooting: State Light Indication RUN: The Green Light Works Normally. ERR: Red Light, Power, Indicator Light, Power Indicator Control Signal Definition: PUL and: stepping pulse signal input side or positive pulse signal input positive terminal PUL-: Negative input of negative input pulse signal or positive pulse signal DIR and: input the positive direction step direction signal or input positive terminal negative pulse signal DIR-: Negative terminal for step direction signal input or reverse pulse signal input in negative direction EN and: Offline can reset the signal input EN-: Offline resettable signal input negative 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.
