Hi, I have been developing motor controller around the imc102t device... i have tested several examples under various conditions and have been working on fine tuning motor and pfc control parameters. Randomly today when i uploaded a new configuration file for a test run with the motor, i got an AC input frequency fault showing on the dashboard of ISD. I can still start and run the motor but i can not identify what has caused this fault to show up... the connected ac line tests at 59.99hz on my multimeter, so it does not appear to be a problem with the ac line frequency. i checked signal continuity and resistance values for all the components from the ac line up to the input pins on the chip with no issues detected. I didn't change any parameters in my configuration that should have affected frequency detection so i am quite confused as to what is going on. 

As i said i can still run the motor but i would like to understand what is going on here to hopefully avoid future problems

Thanks, Dan

Hi

Once the problem occurs is it persistent or a one time condition.

Best Regards
