Problem Integrating ATI-DAQ F/T Sensor

[th.st.]

Hello!

Since this week we have a problem with our ATI-F/T sensors.

The forces and torque values are measured by the sensor and collected as voltages by the DAQ card (NI-6220).

In our LV program we are using libraries etc. provided by ATI-IA to convert the voltage values into force/torque values by means of a calibration matrix. To calculate this calibration matrix LV loads a calibration file (*.cal) and reads the calibration values provided by ATI-IA.

Unfortunately LV doesn't read the *.cal files anymore.

No error code shows up and the VI isn't broken, too.

The voltages are still put our by our VI so "just" the transformation isn't working at the moment.

Now we don't know exactly what happend and why LV isn't able to read the *.cal file anymore.

The LV version we are using is 12.0f3.

We hope we can get some help from you.

Thank you in advance!

Hi there!

We were able to break down the problem to a library from ATI.

The library is available here (atidaqft-mx.llb).

Using only the single VIs contained inside the library and setting breakpoints to read out the values of the single steps we were able to see were the "error" is located.

The last A x B function only gives out a NaN values. Although the values before are sent correctly.

Do you have a idea how to solve this problem?

Thank you!
