1. MA MB phase line output connection motor 2. 5V GND motherboard comes with 5V power supply (current does not exceed 30MA) 3. VCC GND motor main power supply (external DC power supply) 4. SC speed pulse signal output. positive and negative reversing control interface (also can be connected to the external switch) 5. VR speed control signal input (onboard with potentiometer speed control can also be connected to 0-5V analog simulation PWM duty cycle to support dual signal input speed regulation). Ha Hb +5V GND Hall signal Power input, generally with Hall's motor has five corresponding lines Full patch process Stable performance with positive/reverse function Product Name: 400W Brushless Hall DC Motor Driver Model Number: ZS-X11D1 Operating voltage: 9-60V Maximum current: rated 16A 20A Maximum power: 400W Overcurrent protection: Yes Weight: about 93g. Precautions: 1. The power supply circuit on the main board has no fuse, and the built-in self-addition will cause permanent damage to the chip on the board (even 2 seconds is not allowed). 2. During normal operation, there is sampling overcurrent protection at the motor output. Since the module power and current are very large, please do not short circuit when the module is not working normally. Once the short circuit has the possibility of burning , the first wiring test machine Please use small current and low voltage test, after ok, then pass high current and high voltage, because it is bare board module, pay attention to the wiring line insulation, strong voltage is not allowed to contact the board parts. 3. Do not connect the motor that is obviously inconsistent with the voltage and current of module or is far away from the motor to avoid inexplicable damage. colour:As shown Material:plasticsize:63 x 45 x 31mm Package Contents: 1 x Driver Board 1 x group line Only the above package content, other products are not included.
