Hi Kuroro,
Thanks for posting on the forum, we will certainly do our best to help you out!
The Power up reset error can typically be cleared in several different ways. First, it is often possible to clear this error by going to Measurement and Automation Explorer and Initializing your Motion controller hardware. When this doesn't help, sometimes the best way to clear this status is by running a LabVIEW VI that contains nothing but the "Clear Powerup Reset Status" VI. This VI can be found on the LabVIEW palette at All Functions>>NI Measurements >> Motion >> FlexMotion >> Advanced >> Clear powerup reset state.vi.
One of these two things will hopefully resolve the problem you are experiencing. I am not sure what you mean when you say that you put a web browser program on your motion controller, but if you have any other questions, feel free to ask. As always, the more information the better!
Hope this helps,
Robert
