Abstract
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.
Claims3
An adaptive motion controller for driving a servo motor comprising
- 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
- control means including means for driving the servo motor in a test mode including
- means for setting said voltage command at a selected voltage,
- means for sequentially setting said frequency selector with a series of different frequencies,
- means for operating said servo motor at each frequency, and
- means for determining which frequency of said series of frequencies has the lowest current feedback, and
- wherein said control means further comprise means for driving the servo motor in a normal mode including means for setting said frequency selector at the frequency which has the lowest current feedback.
