RPM Calculation Using NI 6001 and DAQmx

[mihneeaaaaaaaa98]

Hello, I need some help with an RPM calculation. I’m using an NI 6001 and have extracted pulses from DAQmx, where 4 pulses correspond to one full rotation. Now, I need to determine the real-time RPM of the rotating system.

For example, I have a motor, and I need to measure its RPM in real-time based on the pulses received. What would be the best approach to achieve this using DAQmx? Any suggestions or guidance would be greatly appreciated!

Thanks!

Since USB-6001 has a limited counter function, I think the best approach is to acquire the pulse waveform using analog input and then use Pulse Measurements VI to compute the period.

Could you be more specific about how Pulse Measurements VI processes the signal? I’d like to understand its accuracy and whether there are any limitations in detecting the period using this method.
