rexroth博世力士樂伺服驅動器維修：隨著伺服系統(tǒng)的大規(guī)模應用，伺服驅動器使用、伺服驅動器調試、伺服驅動器維修都是伺服驅動器在當今比較重要的技術課題，越來越多工控技術服務商對伺服驅動器進行了技術深層次研究。當力士樂伺服驅動器報警F276故障Absolute Encoder Error。我們首先應該弄明白其含義絕對編碼器錯誤。

注塑機力士樂伺服驅動器維修案例：

Description:故障說明：

When turning off the drive controller with a absolute encoder (multiturn), the actual feedback position will be stored. When powered up, the absolute position given by the encoder is compared to the stored position. If the deviation is larger than the paramaterized "P-0-0097,AbsoluteEncoderMonitoring Window", the error "F276, Absolute Encoder Error" will appear and be given to the control system.當用絕對編碼器（多匝）關閉驅動控制器時，將存儲實際反饋位置。通電后將編碼器給出的絕對位置與存儲的位置如果偏差大于參數(shù)化的“P-00097，AbsoluteEncoderMonitoring Window“，錯誤”F276，Absolute

“編碼器錯誤”將出現(xiàn)并提供給控制系統(tǒng)。

Cause:原因：

1. Turning on for the first time (invalid stored position).

首次打開（存儲位置無效）。

2. The motor was moved further than allowed by the parameter in the absolute encoder monitoring window, P-0-0097, while it was turned off.當電機關閉時，電機的移動超過絕對編碼器監(jiān)控窗口P-0-0097中的參數(shù)所允許的范圍。

3. Incorrect position initialization位置初始化不正確

Remedy:解決措施：

1. Press S1 to reset the error and set the absolute position.

按S1重置錯誤并設置絕對位置。

2. The motor was moved while turned off and sits outside of its permissible position. Check to see if the displayed position is correct in relation to the machine zero point. Reset subsequent errors.電機在關閉時移動，位于其允許位置之外。檢查顯示的位置相對于機器零點是否正確。重置后續(xù)錯誤。

3. An accident may occur by accidental shaft movement. Check absolute position informartion. A feedback defect is present if the absolute position information is false. The motorshould be exchanged and sent to the INDRAMAT Customer Service .意外軸移動可能會發(fā)生事故。檢查絕對位置信息。如果絕對位置信息為假，則存在反饋缺陷。應更換電機并聯(lián)系上海仰光電子客戶咨詢部。
