(This drive is not cooling under the conditions of rated current 12A, rated current 12A ~ 15A need to do simple cooling, 15A ~ 20A need to do thick heat. Motor rated power is generally refers to the output power, consider the motor work loss, so the calculation Rated current to be considered motor efficiency, rated current = rated power / rated voltage / efficiency)
How to use it
1. Use the microcontroller to control the motor rotation wiring method
Single-chip power supply to connect the drive module COM; PWM pin to the microcontroller's PWM output, for speed, or directly connected to the high-level full speed operation; IN1, IN2 and the microcontroller's two IO connected to control the motor is reversing and Brakes; 5VO can provide 5V power supply for the microcontroller.
2. Use only the keys to control the motor reversing the wiring method
PB1 and PB2 are two keys. When the PB1 is pressed and PB2 is not pressed, IN1 is high, IN2 is low, the motor is turning; when PB2 is pressed and PB1 is not pressed, IN1 is low, IN2 is high, Motor reverse; when PB1 and PB2 are bounced, IN1 and IN2 are low, the motor brake.
3. Use OUR PWM generator to the motor speed control wiring method
PWM generator can be set by the key, select the frequency and duty cycle to control the motor speed; PB1 and PB2 for the two buttons were to control the direction of rotation of the motor, when PB1 and PB2 are bounced, the motor is braking.
Precautions
1. The drive supply voltage should be between 6-36V. If the power exceeds the rated voltage, it may burn the drive; the voltage is too low, the load current is large, may also cause the drive to burn. It is recommended to connect the 20A fuse in series at the power supply.
2. In the forward and reverse switching time is best to brake more than 0.1S and then reverse, otherwise it may damage the drive.
3. Since the control signal line is very fragile, any signal lines (orange terminals) of the control signal can not be routed together with the wiring of the power supply or motor during use. Otherwise, the drive may be burned and difficult to be repaired.
4. When the drive is powered down, do not turn the motor quickly, or the motor's electromotive force may burn the drive. If the application requires the drive to power down when the machine should also quickly turn the motor, it is recommended in the drive motor interface string of a relay, relay coil and drive power supply. In this way, when the power supply is turned off, the relay disconnects the drive from the motor.
5. The drive should be connected to the motor before it is powered on, otherwise it may burn the fuse or drive.
6. Motor interface must not be short-circuited, otherwise it may burn the fuse or drive.
7. Note that the drive does not get wet, do not let the components on the drive board short circuit, do not touch the components on the board pins and pads.
8. Please carefully read the product before use, if your error caused the module damage, or you have unauthorized replacement of the module device, no refund.
