Speed regulation
Bld-750B have 5 speed control method as following.
1 Via built-in potentiometer
Motor speed is increase when RV knobs is rotated clockwise, when anticlockwise, motor speed decreases. If user use other speed modes, RV should be rotated anticlockwise to limit position.
2 Via external potentiometer
Use a suitable potentiometer with a resistance value of 10kΩ; When connect external potentiometer, the middle terminal connects to SV, the other two terminals connect to +5V and GND
① RV should be rotated anticlockwise to limit position.
② Notice the connection sequence of the potentiometer.
3 Via external analog signal 0-5V
When use external analog signal, the built-in potentiometer RV must be OFF (RV should be rotated anticlockwise to limit position).

4 Speed setting via pulse frequency
the motor speed is changed as the variation of pulse of frequency.
