fan control through PWM using digital output of sbRIO

[satoo]

Hi all.

I am a new user of LabVIEW, so excuse if the question sounds basic.

I want to control two 4 wire fans (required for ventilation purposes) using PWM outputs. I am using sbRIO 9627 and would like to control digital RIO Mazzine ports (DI01, DI02...) to control the fans. I would like to know what could be the easiest logic in terms of LabVIEW VI that can control the fans rpm.

Hi Satoo,

Sorry you've been waiting a while to hear back. I am assuming that you have managed to have this fixed by now, but if not, you can see some example code here:

There's also this white paper that briefly describes PWM: https://forums.ni.com/t5/Example-Code/Pulse-Width-Modulation-PWM-IP-Core-for-LabVIEW-FPGA/ta-p/39961...

Thanks,
