F822 Motor Encoder Failure: Signal too Small
電機(jī)編碼器故障：信號(hào)太小

Description:說明：
The motor encoder signals are monitored.
監(jiān)測(cè)電機(jī)編碼器信號(hào)。
If the signal amplitudes as measured via AK1 and AK2 are outside of the allowable region between Uss = 12.0V and Uss = 18.0 V, then the error message appears. 如果通過AK1和AK2測(cè)量的信號(hào)幅度在Uss=12.0V和Uss=18.0V之間的允許范圍之外，則出現(xiàn)錯(cuò)誤消息。
The drive becomes torque-free and an optional brake is immediately activated.
驅(qū)動(dòng)器無(wú)扭矩，可選制動(dòng)器立即啟動(dòng)。

Cause:原因：
1. Defective feedback cable.
反饋電纜有缺陷。
2. Defective feedback.
反饋有缺陷。

Remedy:解決措施：
For 1. Check the feedback cable.
檢查反饋電纜。
Lay the power cables separate from the feedback cable.
將電源電纜與反饋電纜分開放置。
The cable shield must be connected to the drive controller.
電纜屏蔽必須連接到驅(qū)動(dòng)器控制器。
(See also project reference of the drive control).
（另請(qǐng)參見驅(qū)動(dòng)器控件的項(xiàng)目參考）。
For 2. Exchange motor.更換電機(jī)。
