The preferred operating frequency for the fan is 25kHz.
PWM signal frequency range from 18kHz~30kHz.
At 100% duty cycle, the fan will operate at maximum speed.
At 0% duty cycle, the fan is not rotate.
The fan will default to operate at maximum speed when the speed control input is left
connected.
At 25kHz with 20% duty cycle (Vcc = 24VDC), the fan will be able to start from a dead stop.
