Clear power up status question

[sameervm]

Hi,

I have been using NI-Motion controller 7334 along with UMI-7764 for a while.  Today the error 70072 "The FlexMotion controller is in power up reset state. Please execute the Clear Power Up Status function or VI before sending any commands to the controller" was reported when I tried to execute my application VI. What could have happened to cause this error suddenly?

I initialized the controller using measurement and automation program.  After this initialization, the error is gone and stepping motors move, but other functions do not work in my application VI.  If I restart the computer, the error returns.  Also, the stepping motors move when computer is OFF. I am not sure if I am doing the correct procedure to clear power up status.

Any help to resolve this issue is appreciated!

Just to give an idea about my knowledge level, I am not familiar with LabView programming.

Thanks!

Hello Sameer,

The motion controller goes into the power up reset state after the computer or the motion controller is reset.  Initializing the motion controller from the NI Measurement and Automation Explorer (MAX) is a valid method of clearing the motion controller of this state. 

Can you elaborate on what other functions in your VI stop working after you initialize your motion controller in MAX? 

If your motors move when the computer is turned off, you may not have the inhibit lines connected properly.  

Best Regards,

Hello McCarty,

Thank your for the reply.  I could make my application VI work now.

Is it possible to set not to "reset the power up state" everytime computer or controller restarts.

Thank you!

Hello Sameer,

Attached VI will :

1. Check if the controller is in the Power Up Reset state
2. Clear the Power Up Reset state if needed
3. Initialize the controller. Settings Name must be an existing motion configuration.
   

Hope this helps
