Nonlinear curve fitting - max iterations exceeded (error -23026)

Hello,

In my application I'm using the nonlinear curve fit VI (Levenberg-Marquardt) to fit data acquired continuously using a DAQmx task. Often during the setting up of the instrument, the curves are not yet "fittable" and the max iterations defined in the termination parameters is reached.

This is OK but the problem is that it generates an error (-23026) that will stop the execution of the VI.

How can I ignore this error and continue running the VI until the termination is controlled by the tolerance parameter?

Regards,

Bernard
