Notes to take when the幫我翻譯ㄧ下好媽

When the vertical axis exists, select the DC power supply that has a long voltage

hold time to decrease the amount of vertical axis falling during power–off

(including a power failure).

If the operating voltage drops to less than or equal to 21.6V, the CNC releases

servo activation. Therefore, when the hold time for 24 VDC during AC

power–off is too short, servo activation is released before the breaks are applied

because some peripheral circuit detects power–off. This may increase the

amount of vertical axis falling.

Generally, a power supply with sufficient power capacity tends to increase the

hold time during power–off.

    當垂直的軸存在時,選擇有久電壓佔用時間減少垂直的軸下落在力量期間的相當數量的直流電源(包括電源故障)。 如果工作電壓下降到小於或等於21.6V, CNC發布伺服活化作用。 所以,當佔用時間為24 VDC在AC力量期間是太短的時,發布伺服活化作用,在斷裂是應用的之前,因為一些周邊電路查出力量。 這也許增加相當數量垂直軸下落。 通常,在力量期間,電源以充足的功率電容傾向於增加佔用時間。
