Setting SW-Limits..?!

When I am setting the SW-Limits in Max it works fine for both directions for my connected stepper motor. But when I do the same with LabView

it does not work and I also do not see any changes in Max after refreshing the parameters.

 

When I am reading the SW-Limit status (LabViwe .vi) of the motor it gives me not the correct setting whatever i have set before. It seems that I can

not set and read the correct settings from LabView, but it works when I set any limit parameters in Max.

 

For my LabView code I was directly using the standard VI's from NI - not my own code.

 

Is there anybody who knows where the problem could be?

 

thanks in advance

Hi,

 

could you please provide a little more information on your system?

 

1. Which board are you using to drive the motor?

2. Which software versions (LabVIEW, drivers)?

3. You mention that you use standard LabVIEW VIs. Could you please specify which functions you are using, and in which order?

 

Thanks.

 

Regards,

Joseph
