There is no way of determining the position of a servo that has been plugged in, until it's position has been set. Therefore, if an initial position is important, it should be set as part of initialization.</p><p>The range here is -23 - 232, each corsponding aproximately to an angle in degrees. -23 corresponds to a PWM of 0, which means that the motor is not being driven at all, and so can be freely rotated. Note that most servos will not be able to operate accross this entire range. Typically, the range might be 25 - 180 degrees, but this depends on the servo.</p></div></div><div class="section"><div class="sectionTitle" onclick="toggleSection(this.parentNode)"><img src="../icons/collapse_all.gif" /> Exceptions</div><div class="sectionContent"><table class="exceptions"><tr><th class="exceptionNameColumn">Exception</th><th class="exceptionConditionColumn">Condition</th></tr><tr><td><a href="8edb365f-379f-1439-651c-18f12eafc13e.htm">PhidgetException</a></td><td>If this Phidget is not opened and attached, or if the index is out of range.<br /></td></tr></table></div></div><p><div id="footer"> </div>Assembly: Phidget21.NET (Module: Phidget21.NET) Version: 2.1.3.23</p></div></body></html>?? 快捷鍵說明
