From the RPLIDAR manual:

Since USB adapter’s control signal MOTOCTL is fixed to high level, RPLIDAR’s scan motor is
always rotating at its highest speed which makes RPLIDAR working on a relative high scan
frequency. You can configure RPLIDAR’s scan frequency by controlling motor speed.
By connecting MOTOCTL signal to the device has PWM output function such as MCU’s
PWM output I/O port, RPLIDAR’s scan frequency can be locked in a proper value by adjust
duty ratio of PWM using the scan frequency feedback provided by RPLIDAR core.

If you need more help for this sensor, ask your questions to RPLIDAR support.
