Im trying to drive a ACIM 3 phase motor from a disntance. The dev kit is +- 80 meters away from the motor. the motor doesnt spin (or at least its trying to spin) with the new parameters which i have got from the instaspin gui app. is there anyway to compensate cable length with in code.

Im using lab 2a.

    re-identify the motor with the wiring, or at least run RsRecalc to get a better Rs value.

    The Ls may have changed as well....you can also try just using a meter by hand if for some reason the motor can't be ID'd in the installation.
