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