伺服馬達|執行回原點動作,跑出兩個點?action execution back to the origin, ran out of the two points?

一般回原點動作,都是先到機台的原點sensor,再找馬達的Z點。
General movement back to the origin, the origin of the machine are first sensor, and thenfind the Z motor point.

如此一來,應該只會有一個點,不應該跑出兩個點位!?
So, it should be only one point, two points should not run out!?

但如果在碰到原點sensor時,也剛好在馬達的Z點呢!!
If you encounter the origin sensor, the Z also just point it at the motor!!

有可能這次原點,剛好過Z點一個脈波,
May be the origin, just over a pulse point Z,

下次回原點剛好在Z點前,
Next back to the origin point in the Z just before the

就會產生回原點有兩個不同點的情形了。(兩個點位的距離是馬達一圈的距離。)
Will produce two different points back to the origin of the case. (The distance between twopoints is the distance around the motor.)


解決方式:
把原點SENSOR,移開現在的位置,就可以了。
Resolution:
The origin SENSOR, remove the current position on it.
