<b>Parameter notes:</b><br /></p><p><ol><li><b>Ls</b>, <b>Lp</b>, <b>Lpp</b> must all be specified.</li><br /></p><p><li>The initial value of <b>Pm</b> or the value coming from an separate mechanical load model, if used, is multiplied by speed raised to the power <b>D</b> to determine the effective mechanical load seen by the motor.</li><br /></p><p><li>The parameters <b>Vt</b> and <b>Tv</b> define under-voltage tripping logic.  A timer is started if the terminal voltage falls below <b>Vt</b> per unit and continues to run until voltage rises above <b>Vt</b>.  If voltage has not risen above <b>Vt</b> when the timer reaches <b>Tv</b> the motor is tripped immediately.</li><br /></p><p><li>Per unit parameters are on the motor MVA base.  The MVA base is calculated during initialization as the initial motor<b> P</b> in MW divided by the loading factor (<b>Lfac</b>) parameter.</li><br /></p><p></ol><br /></p>
