Servo amplifierThe function is to synthesize and amplify multiple input signals and feedback signals, and output corresponding signals to control the servo motor to rotate forward or backward according to the polarity of the synthesized signal. When the input signal and feedback signal are balanced, the servo motor stops rotating and the output shaft of the actuator stabilizes at a certain position. It mainly consists of a preamplifier, trigger, thyristor main circuit, and power supply. To meet the needs of complex multi parameter adjustment, three input signal channels and one position feedback signal channel are set up. Therefore, it can simultaneously input three input signals and one position feedback signal. In a simple adjustment system with a single parameter, only one input channel and feedback channel are used. Equivalent to a three position contactless relay and possessing significant power amplification capability.

A servo amplifier is a controller used to control servo motors, and its functional characteristics are summarized as follows:

1. Status display. The status of the servo amplifier can be displayed on a 5-digit 7-segment digital display.

2. Location system. As long as the origin is set once, it can work without resetting the origin when the power is turned on in the future.

3. Gain switching function. Different gains can be used during the operation and stop of the servo motor, and gains can also be switched during operation through external terminals.

4. Adaptive vibration suppression control. Adaptive vibration suppression control refers toServo amplifierAfter detecting the resonance point of the mechanical system, the filtering characteristics are automatically set to suppress the vibration of the mechanical system.

5. Low pass filter. Can suppress mechanical resonance that may occur when the response speed of the servo amplifier is too high.

6. Mechanical analyzer function. When using a personal computer equipped with servo setting software, the resonance frequency and characteristics of the mechanical system can be analyzed.

7. Mechanical simulator. According to the measurement results of the mechanical analyzer, the operation of machinery can be simulated on a personal computer.

8. Gain search function. By using a personal computer, the gain can be automatically adjusted to find a gain value without overshoot in a short period of time.

9. Position slope function. It can achieve smooth acceleration in response to pulse train input signals.

10. Input signal selection. Input functions such as forward start, reverse start, servo start, etc. can be defined to any pin.

11. Automatic adjustment. Even if there is a change in the load applied to the motor shaft, it can stillServo amplifierAdjust the gain to the ideal state.
