error 200745 occured at DAQmx

[Ludz]

Hello everyone.

Does anybody knows about this "error-200745 occured at DAQmx"

everytime I used 57.6KHz frequency and Initial delay of 1.

Looking forward of your help..

thanks and regards,

I think your duty cycle is too small.

Have a look at this KB 

Pulse Width Modulation (PWM) Using NI-DAQmx and LabVIEW

I'm using three sets of duty, 0%, 60% and 100%. But when my frequency is 25KHz, no problem was encountered

during program execution.

Hi, Ludz.

Could you give me some more information about your application?  What device are you using?  Are you generating a pulse train with an Analog Output channel, as indicated in a response of the first post?  Are you using an Example program?

I hope you're having a great day!

Hello Sara,

I'm using PCI-6221. Please check my attachment for your reference. My program was came also in NI examples

and modify it for my application.

regards,

Hi Ludz,

Do you get the error for every duty cycle?  Do you know which frequency or frequency range the program will give you this error?  What example program did you start with? One example you can try is the PWM-Counter Output.vi located in the example finder.  You can find the example finder at Help>>Find Examples.  When this opens, select the search tab in the top left and search for PWM.  I would try running this example with the same settings as your other program to see if you see the same behavior.
