Connecting Terminal (I/O PORTS)
1. VCC: Power supply 20~40VDC
Remarks: avoid exceeding 40V by all means, for fear damage of module.
2. GND: VCC power supply corresponding ground wire
3. B+ and B-: Step motor one-phase wire package
4. A+ and A-: Step motor other one-phase wire package. (If finding operating direction of motor is reverse, adjust A+ and A- simply)
5. +5V: Max. Output current of a group of power supply provided by module is less than 100mA.
6. VREF: Current reference level of motor wire package is used to test current value of motor.
7. CP IN: Clock pulse input terminal (rising edge is effective) and connection diagram see right.
8. 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.
9、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.
10. NC: Empty, no connected
11. SGND: Light coupling negative pole
Remarks: adjusting built-in potentiometer can make current adjust during 0～1.5A: clockwise adding and anticlockwise minishing.
Cautions:
1. Motor Connecting: this driver module applies to two-phase and four-phase mixing step motor with rated current of 2A below. Please note that motor wire shouldn't be connected wrongly, otherwise driver module will be burnt out. Connection diagram see follows:
2. Current Adjusting: connect direct-current voltmeter among VREF and GND, start motor (frequency is more than 100Hz) and adjust potentiometer (CURRENT), then current inside wire package can reach required value and relationship between wire package current and VREF is that Ｉis equal to 0.67ＶＲＥＦ
3. Avoid contacting corrosive gas.
4. When current is higher or working current exceeding 0.7A, please fix module on big metal envelope or add axial flow fan outside to eliminate heat, so that module can operates reliably for a long time.
