F226:Description:說明：

The level of the DC bus voltage will be monitored by the drive controller. If

the DC bus voltage falls below a minimal threshold, the drive

independently shuts down according to the set error reaction.

直流母線電壓的水平將由驅(qū)動(dòng)控制器監(jiān)控。如果直流母線電壓低于最小閾值根據(jù)設(shè)定的錯(cuò)誤反應(yīng)獨(dú)立關(guān)閉。

Cause:原因：

1. The power source has been interrupted without first switching off

the drive enable (RF).

電源在未首先關(guān)閉的情況下中斷驅(qū)動(dòng)使能（RF）。

2. Disturbance in the power supply

電源干擾。

Remedy:排查思路：

For 1 Check the logic regarding the activation of the drive within

the connected control.

檢查內(nèi)部驅(qū)動(dòng)器激活的邏輯連接的控件。

For 2 Check the power supply.

檢查電源。

The error can be cleared by removing the control enable signal.

可以通過移除控制啟用信號來清除錯(cuò)誤。
