BLDC Controller BX-1

12V-24VDC 8A Control Board Explanation：

Voltage: 11V-28V.

Current: Cont. Max=8A (12V/24V),

Current protection: 9 A(12V/24V),

Max Electric speed: 240000rpm(No hall); 60000rpm(Hall)

Speed control model: open loop or close loop control (Switch to select),

Speed adjustable way: 1. internal pot-meter(SPD2), reduce speed by rotating ccw and increase in CW.

Speed adjustable way 2: Outer Pot-meter. Add a pot-meter between : "SPD" and "GND", or add a 0-5v power supply to adjust speed outer of "SPD". It's linear between speed and voltage Normally, we select 1 which has a better result from above 2 ways, please make a short circuit between "SPD" and "GND" if need way 1 only. If need way 2only, please rotate internal pot-meter to mnimum in CCW. Start/Stop: Star if make a short circuit between "RUN" and"GND".Stop if open.

CW/CCW: CCW if make a short circuit between "REV" and "GND". CW if open.

Speed signal: “PLS" is pulse output.3 pulse 1 rpm. Pulse amplitude is +5v.(note: Rotor speed=electric speed/poles(pairs)).

Protection function: Current protection, thermal protection, voltage protection, motor stall protection, starting protection,etc.

Note: When use Hall model (suitable for 120 degree phase of sensor）you need to connect 5 wires of Hall first(don't make wrong connection of +5v and GND) and then connect 3 wires of motor, as 3 phase of Hall and 3 phase of motor mus correspond to each other. If motor works abnormally. please modify connection of motor wire, 6 connections totally. When power on, controller will recognize if has a hall or not. In case Hall wire is connected, motor works in Hall model, or works without Hall.
