Panasonic servo motor use effect how, in addition to related to the performance of the motor and drive, servo drive the adjustment of the parameters is also a crucial factor.How to adjust the parameters of the servo driver?Let‘s take a look at.
Servo drive is the main performance parameters of the adjustment has three: the proportions of the position loop gain, speed loop gain, integral time constant speed ring.
Principle of parameter adjustment speed loop, speed loop system is stable (not oscillation) under the premise of allowing overshoot and only one wave head, overshoot is the fastest speed loop response, and the system stability.
Speed loop proportional gain and integral time constant using default values can meet the needs, adjust the proportion of position loop gain, can reduce the position offset, improve position following features.Suggested that adjust the proportion of position loop gain.
Proportion to the position loop gain adjustment principle is in position loop system stable work, position without out-of-tolerance (overshoot), increase the proportion of position loop gain, to minimize the position offset.Simple method is to increase the proportion of the position loop gain, until the system position error (overshoot), and then reduce the proportion of the position loop gain, is has good stiffness proportion of position loop gain.
Servo drive and system how to earth?Correct shielding meet is located in the reference potential point is inside of the circuit.This point depends on whether the noise source and receiving ground at the same time, or empty.To ensure that current in the same point grounding makes the shield will not through the shield.
1. In the majority of servo system, all the public and the earth in the signal terminal is meet together.Many kinds of way to connect the earth produces ground loops can easily affected by noise and produce flow in different reference points.
2. In order to maintain a constant reference voltage command, to the signal of the servo drive to received signals from the controller.Will receive the external power supply, which will harm the work of the controller and the servo driver (such as: the encoder 5 v power supply).
3. Shield grounding is relatively difficult, correct shielding meet is located in the reference potential point is inside of the circuit.This point depends on whether the noise source and receiving ground at the same time, or empty.To ensure that current in the same point grounding makes the shield will not through the shield.
