Hi I have a fan, model number FFC0612DE, the datasheet is here
http://www1.futureelectronics.com/doc/DELTA PRODUCTS CORPORATION/FFC0612DE-F00.pdf
for one of my projects I need to control the speed via PWM, I tried a pwm signal direct to the read lead (VDD input) and I managed to get control, the best frequency was around 1.3KH.
Then I decided to look at the datasheet as the fan has 4 wires, what has me confused is the difference between the yellow and the blue wire.
Blue wire is described as Frequency
and yellow described as control PWM.
I am assuming I send a pwm signal down the yellow wire, but what is the blue wire for?
Thank you for any help
LG
PS please go easy on me I am only 13, but keen to learn
