One stepper motor driver 3A 20V-40VDC
* Applicable voltage range :20 40VDC
* Adapt to two-phase and four-phase mixing step motor below 2A.
* Input Voltage: 20 40VDC single voltage power supply
* Current: Current of this module can be adjusted among 0 1.5A
* Driver Type: Full-bridge PWM micro-step driver
* Operating Mode: Half step and 1/8 step
* Operating Characteristic: Excel in former motor ex-factory index
* Protecting Mode: Overheating protection and lock automatic semi-flow
* Overall Dimension: 99mm 65mm 30mm
* Operating Environment: Temperature -15 40 and humidity<90%
Connecting Terminal (I/O PORTS)
* VCC: Power supply 20~40VDC
* GND: VCC power supply corresponding ground wire
* B+ and B-: Step motor one-phase wire package
* A+ and A-: Step motor other one-phase wire package. (If finding operating direction of motor is reverse, adjust A+ and A- simply)
* +5V: Max. Output current of a group of power supply provided by module is less than 100mA.
* VREF: Current reference level of motor wire package is used to test current value of motor.
* CP IN: Clock pulse input terminal (rising edge is effective) and connection diagram see right.
* CW/CCW: Motor operating direction control and operating direction of motor can be changed through controlling power level of this terminal.
Remarks: CP IN and CW/CCW terminals are both +5V controlled; if control signal is more than +5V, please connect resistance in series to control light coupling on-state current among 10~20A.
* HALF/DIV: Motor operating mode adoption: when high power level, the motor operates at half step and when low power level, the motor operates at 1/8 step.
* NC: Empty, no connected
* SGND: Light coupling negative pole
Remarks: adjusting built-in potentiometer can make current adjust during 0 1.5A: clockwise adding and anticlockwise minishing.
