Before the servo positioning operation, it is generally necessary to perform the origin return first, otherwise the servo motor may be stopped, saying that it will be "started when the origin return is not completed". So, why origin regression?
The necessity of origin regression
The so-called positioning is to let the servo motor go to a confirmed position. This direction can be incremental or absolute.
For example, if we are on the road now, we have to go 10 meters forward, which is equivalent to adding 10 meters to our bearing, and this 10 meters is an azimuth increment. And if we want to go to a coffee shop somewhere on this street, we need to know its address, assuming that the address of this street is not the house number, but 0 meters from one end of the street. In this way, we can confirm the address of each direction on this street, for example, the address of this coffee shop is the direction of 100 meters of this street, then this 100 meters is an absolute * direction, no matter which direction we are in, we can find this coffee shop by walking to the direction of 100 meters of this street.
In the positioning command, it is divided into incremental INC instruction and absolute ABS instruction.
Incremental (INC) method
Starting from the current stopping position, you can locate yourself by specifying the direction and amount of movement.
Absolute* Value (ABS) method
Locate to the specified address, which is the bearing based on the origin.
Therefore, when we need to carry out absolute * value positioning, we need to have an address on the corresponding mechanical system, which also requires a datum direction, and confirm the address of each direction on the mechanical system through this datum orientation. And this datum orientation is called the origin in the servo positioning system.

The difference between KUKA robot inverter and servo manipulator
The servo manipulator controls the manipulator's actions through servo motors and servo drives. The servo manipulator has higher control accuracy than the frequency conversion manipulator and is expensive.
Inverter manipulator is an automatic production equipment that can imitate some functions of the upper limbs of the human body, and can be automatically controlled according to predetermined requirements.
