The problem of servo system zero switch

There are many ways to change, which can be selected according to the required accuracy and actual requirements. Can be done by the servo motor itself ( Some brand servo motors have complete return point function) , Can also be done by the upper computer with servo, but the principle of returning to the origin is basically the following. First, when the servo motor looks for the origin, when it touches the Origin switch, it immediately decelerates and stops, taking this point as the origin. Second, when returning to the original point, directly find the Z-phase signal of the encoder, and when there is a Z-phase signal, immediately decelerate and stop. This method of returning to the original is generally only applied to the rotating shaft, and the returning speed is not high and the accuracy is not high.
