Brushless DC Motor 48V QW-BLD-750 BLDC Engine Controller Speed Regulator BLDC Driver

NOTES 1. Please confirm that your motor is a brushless motor 2. Ensure that your motor has eight wires 3. The wiring in the figure below refers to the wiring of the driver that matches our company's motor. Perhaps the motor wire definition of your motor is different from ours, so you need to conduct a matching test until the forward and reverse rotation of the motor can work properly, indicating that the motor and driver wiring are successful
1.Fourmodes of speed regulation:(1). External potentiometer: through this potentiometer speed regulation;Use a suitable potentiometer with a resistance value of 10K, connect middle terminal with SV terminal, and the other two terminals are respectively connected with REF+ terminal and COM terminal. (2) . External voltage: external 0-5VDC voltage speed regulation;When the input voltage is 0.25V, the motor speed is 5% of the maximum speed; When the input voltage is about 4.7V, the motor speed is the maximum value.
2. Alarm output ALM signal:The fault output signal of the motor or drive is 5V under normal circumstances; the level is 0V when a fault occurs.
3. Positive inversion function:F/R:(1) low level input or when F/R and COM are connected, the motor will rotate anticlockwise (2) High level input the motor will rotates clockwise,
4. Start-stop :(1). low level input or when EN and COM are connected, the motor runs. (2). High level input the motor will slowly stops,
5. Brakingthe motor runs when the low level is added or EN and BRK are connected The motor brake stops when a high level is added or port suspension;
6. Peak current settingEquipped with a motor protection function, the driver provides options to set desired current number in the P-sv knob. Please note that the rate of change is ±10% .
