When you set the microstep , pls stop the driver working.The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure .Output current setting Users can set the driver Microstep by the SW1-SW5 five switches. The setting of the specific Microstep subdivision, please refer to the instructions of the driver panel figure..Double pulse setting SW7 sets pulse mode, setting “on'' as double pulse mode, setting “off'' as pulse + direction mode.,CW+/CW is Clockwise ,CCW+/CCW- is Counterclockwise , need to confirm the wire of stepper motor .Automatic half current function Users can set the driver half flow function by SW6. "OFF" indicates the quiescent current is set to half of the dynamic current, that is to say, 0.5 seconds after the cessation of the pulse, current reduce to about half automatically. "ON" indicates the quiescent current and the dynamic current are the same. User can set SW6 to "OFF", in order to reduce motor and driver heating and improve reliability.Self test function When SW1-SW5 is OFF , Inner of drive send 1K pulse to test whether the motor,wire,and self is normal.signal Interface PUL+ and PUL- are the positive and negative side of control pulse signal; DIR+ and DIR- are the positive and negative side of direction signal; ENA+ and ENA- are the positive and negative side of enable signal .Motor Interface A+ and A- are connected to a phase winding of motor; B+ and B- are connected to another phase winding of motor. If you need to backward, one of the phase windings can be reversed .Power Interface It uses DC power supply,recommended working voltage is 12-40VDC,power is over 50W,voltage shouldn’t be over 40VDC and below 12VDC.Indicator Lightor There are two indicator lights. Power indicator is green. When the driver power on, the green light will always be lit. Fault indicator is red, when there is over-voltage or over-current fault, the red light will always be lit; after the driver fault is cleared, if re-power the red light will be off..Installation The size of motor driver is 115×68×24 mm,mounting holes is 100mm.Chest and upright installation are ok,we suggest upright installation. During installation, it should be close to the metal cabinet for heat dissipation.signal interface and sequence in time : Inner electric circuit of motor drive : Interface connection and installing size :
