Suitable motor parameters
Motors with a rated voltage of 24V are suitable for motors with a rated power of 115W or less or rated current of 7A or less to work at full capacity for a long time
Motors with a rated voltage of 12V are suitable for motors with a rated power of 40W or less or rated current of 7A or less to work at full capacity for a long time

Notes:
1. The driver power supply cannot be connected upside down. It is recommended to connect a fuse in series at the power interface, and the voltage should be between 6.5 and 27V. If the voltage is overvoltage, the drive module may be burned when powered on.

2. It is recommended that the rated output current of the power supply be more than 2 times the rated current of the motor, so as not to cause the power supply to fail to provide the current required when the motor starts, resulting in the power supply voltage falling and the power supply voltage not reaching the input voltage required by the driver, so that the drive module performs undervoltage protection. Turn off the output and cause the motor to stall.

3. The motor interface cannot be short-circuited, otherwise the drive module may be burned. It is recommended to connect a 10A fuse in series at the motor interface.

4. When switching between forward and reverse, you need to brake above 0.1S before reversing. You can't reverse the motor before it stops, otherwise the driver may be damaged.

5. When the drive module is powered off, do not directly or indirectly rotate the motor at high speed, otherwise the electromotive force generated by the motor may burn the drive module. If the application needs to rotate the motor at high speed when the drive module is powered off, it is recommended to connect a relay in series (NO and COM ends are connected in series) to the motor interface of the driver, and the relay coil is shared with the driver. In this way, when the power supply is powered off, the relay will disconnect the driver from the motor.

6. Be careful not to let the driver get wet, do not let the components on the driver board short circuit, and do not touch the pins and pads of the components on the board with your hands.
