Table 5-3 lists the FC firmware responses in case scenario 2:
• Interval 1 — If the calculated value of the PWM is higher than 100%, the
FC firmware will send a signal to the fan to operate at 100% duty cycle and
trigger sled throttling.
• Interval 2 — If the calculated value of the PWM duty cycle is less than or
equal to 100%, the FC firmware will send a signal to the fan to operate at
the set duty cycle.
• Interval 3 — If the calculated value of the PWM duty cycle is still higher
than 100% again, the FC firmware will send a signal to the fan to operate
at 100% duty cycle and trigger sled throttling for 1 hour.
Table 5-4 lists the FC firmware responses in case scenario 3:
• Interval 1 — If the calculated value of the PWM is higher than 100%, the
FC firmware will send a signal to the fan to operate at 100% duty cycle and
trigger sled throttling.
