The Current Command attribute represents the instantaneous value of the
commanded torque producing current signal, Iq, prior to passing through the
vector current limiter. It is tied directly to the output of torque reference path
after the 1/Kt scaling that represents the torque effort to be applied to the drive's
torque producing Iq current loop. The nominal value for 1/Kt is 1 based on 100%
rated torque being produced by 100% rated current.
