    • An adaptive motion controller for driving a servo motor. The adaptive motion controller has an amplifier including a voltage command which can be set at a voltage at which the amplifier will be operated, a frequency selector which can be set at a frequency at which the amplifier will be operated, a power supply having a current feedback, and a control for driving the servo motor in a test mode wherein the voltage command is set at a selected voltage, and the frequency selector is sequentially set with a series of different frequencies. The servo motor is operated at each frequency, and the frequency of the series of frequencies that has the lowest current feedback is determined and the frequency selector is set at that frequency when the amplifier is operated to drive the servo motor.
    • 一种用于驱动伺服电机的自适应运动控制器。 自适应运动控制器具有放大器,该放大器包括可以设置在放大器将被操作的电压的电压指令,可以设置在放大器将被操作的频率的频率选择器,具有电流的电源 反馈,以及在电压指令被设定为选定电压的测试模式下驱动伺服电动机的控制,并且频率选择器依次设置有一系列不同的频率。 伺服电机在每个频率下工作,确定具有最低电流反馈的一系列频率的频率,并且当驱动放大器驱动伺服电机时,频率选择器被设置为该频率。
