How to set current limit > 8.5A on XTR6-110 supply suing XTR example?

[jbarton]

I am trying to use a Xantrex XTR6-110 power supply for a simple project.  I downloaded the XTR drivers from the NI site and have successfully ran the XTR example VI.  However, when I try to increase the current limit above 8.5A  I get the following error:

Driver Status:  (Hex 0xBFFA0010) Invalid value for parameter or property.

When I enter any current limit below 8.5A it runs fine.

The XTR6-110 has a voltage range of 0-6V and a maximum current of 110A.  I am not sure why I can not go above 8.5A current limit unless the driver is specific for the XTR100-8.5 supply which only has a current max of 8.5A.

I am new to Labview and would appreciate any advice.  Thanks.

Specific drivers for the XTR6-110 exist.

Thanks for your reply.  This is the driver set I downloaded.  Not sure why I can not set the current limit over 8.5A when I run the XTR Example VI.

Hmmm.... it appears that the page for the XTR6-110 simply provides a link that brings you to the generic set of drivers. Unfortunately, that's an IVI driver, which means it just passes the front panel controls into a DLL, so there's no way to see from LabVIEW what the problem is - you'd have to dig into the DLL source code. It's likely these drivers came from Xantrex directly, so you may wish to contact them.

By the way, I'm assuming you're referring to the "limit" control that's underneath the "behavior" control.

Hi, 

You can turn off Range Checking to workaround this error.  To do this, use the Initialize with Options VI, and then input the string "RangeCheck = 0".  You should now be able to set the current limit higher than 9 amps. 

Cheers,
