伺服馬達|自動增益調整，好還是不不好?|Automatic gain adjustment, good or not good?

自動增益調整功能，這個功能很方便。

Automatic gain adjustment, this feature is very convenient.

伺服控制器，會根據目前的扭力輸出，適時的調整增益的數值。

Servo controller, based on the current torque output, timely adjustment of gain.

讓使用者，不用再為調整增益而花費許多時間。

Let users do not have to adjust the gain and spend a lot of time.

但不代表所有的機台，都適合隨時隨地都在調整增益。

It does not mean all of the machines, are suitable for adjusting the gain anytime, anywhere.

特別是CNC機台，非常不適合隨時調整增益。

Especially the CNC machine, is not suitable for adjusting the gain at any time.

例：兩軸CNC畫圓，在0°,90°,180°,270°，都會有馬達反轉的動作。

Example: two-axis CNC Circle, in the 0 °, 90 °, 180 °, 270 °, will have a motor reverse the action.

如果開啟自動增益調整，就會瞬間增益不夠，而讓圓變形。

If you turn on automatic gain adjustment, it will instantly gain is not enough, and let the rounddeformation.

自動增益最好的使用時機是，讓機台在最大負載的情形下，

讓控制器調整增益，調整完畢後，就關閉自動增益調整功能。

Automatic gain the best use of time is to let the machine in case of maximum load,
Allow the controller to adjust the gain adjustment is completed, you turn off the automaticgain adjustment.

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.

Servo motor | Why can not put the origin of the middle to put the limit at the negative side!?!?

Servo motor | Why can not put the origin of the middle to put the limit at the negative side!?!?


Origin are generally placed next to the limit in the negative, almost no one put the middle, is why!?

Servo motors in the past to find the origin, only to find a direction.

If the motor stop position is at the origin of the positive direction, negative direction to find no problem.

However, if the motor stop position is at the origin of the negative direction,
To find the origin or to the negative direction, it will hit the limit.

Although the servo drive has been to find the origin, the encounter limit, will go the opposite direction to find the origin of the function.
However, the relative waste of time will be longer.

People may say, I recorded the coordinates, if it is at the origin of the positive, negative to go aboard,
If it is at the origin of the negative, go out walking.
The question is: first to the positive or the negative go!? For motor after the positive or negative to!?
