702：Rotor position at synchronous machine is unknown

同步電機(jī)的轉(zhuǎn)子位置未知

The rotor position of the synchronous drive is unknown.

同步驅(qū)動(dòng)器的轉(zhuǎn)子位置未知。

Either the rotor position offset or the absolute position could not be read from the encoder or the synchronous drive is used with a incremental encoder and a rotor position identification has not been executed yet.

無(wú)法從編碼器讀取轉(zhuǎn)子位置偏移或絕對(duì)位置，或者同步驅(qū)動(dòng)器與增量編碼器一起使用，并且尚未執(zhí)行轉(zhuǎn)子位置識(shí)別。

The error is also set if the encoder is switched off but the motor configuration needs an encoder.

如果編碼器關(guān)閉，但電機(jī)配置需要編碼器，也會(huì)設(shè)置錯(cuò)誤。

Reset of the error is possible.

可以重置錯(cuò)誤。

The error is set again if the cause of the error has not been corrected.

如果錯(cuò)誤原因尚未糾正，則會(huì)再次設(shè)置錯(cuò)誤。

羅蘭印刷機(jī)鮑米勒驅(qū)動(dòng)器故障修理：

Cause: 原因：

For some encoders, the absolute position can partially no longer

be read out due to contamination of the code dial. 對(duì)于某些編碼器，絕對(duì)位置可能部分不再由于碼盤(pán)受到污染而被讀出。

Remedy: 補(bǔ)救措施：

Replace encoder. 更換編碼器。

Cause: 原因

Encoder cable defective

編碼器電纜有缺陷

Remedy: 補(bǔ)救措施：

Checking of encoder cable, and replacements if applicable

檢查編碼器電纜，如有更換

Cause: 原因：

Encoder defective.編碼器有缺陷。

Remedy: 補(bǔ)救措施：

Replace encoder and carry out new notch angle

更換編碼器并執(zhí)行新的缺口角度
