Use problem solving:
A. Q: Why can't I control the speed control with a microcontroller?
Answer: If your MCU outputs 5V pulses, the series resistance should be reduced (1-10K).
B. Q: When starting and running, the red light will turn on after a while, and then the motor will not turn?
Answer: Check if the power setting is too small, the load is too large, and the motor and drive power are small. If the load is too large, it is recommended to choose a high-power motor and drive.
C. Q: What is the reason for the red light on when powered on?
Answer: This situation indicates a fault alarm, detecting whether there is an error in the relevant input or if the current is too high.
D. Q: My motor sometimes stops for a long time to start during operation, or can it not start?
Answer: This type of problem first checks whether the wiring is incorrect, and if it is correct, checks whether the power supply is too low.
