Tips: Position loop gain of servo system

The position loop gain is the parameter that determines the instruction position following, which has a close relationship with the workpiece surface quality. It is only effective only when the servo drive works in position mode. When the servo motor stops running, the proportional gain of the position loop omcreases, which can improve the rigidity of the motor, namely the locking machine strength.
The reactive mode of the servo system depends on the position loop gain. When the position loop gain is increased, the position loop and the accuracy will be improved, while the adjustment time and cycle time will be reduced. But the position loop gain is limited by the characteristic of the speed loop and the mechanical characteristics. In order to improve the reactive mode, if only the position loop gain is increased, as a whole response of the servo system, it is easy to generate vibration. So please pay attention to the reactive mode while increasing the speed loop gain.

1. Characteristics: If the position loop gain is improved, the higher the reactive mode is, the shorter the positioning time is. Too many increase cause vibration and overshoot.

2. Adjustment principle: We should increase the position loop gain in order to reduce the position lagging while ensuring the system stability of the position loop with the precondition of position not exceeding error (overshoot). The simple method can increase the position loop gain to overshoot, and then decreases the position loop gain, which is the gain of the position loop with good rigidity.
