F248： Low Battery Voltage蓄電池電壓低。力士樂(lè)伺服驅(qū)動(dòng)器警報(bào)原因多種多樣，在我們維修的眾多案例中原因有的集中有點(diǎn)分散，原因各不統(tǒng)一。

Cause:原因：

The connected motor has an absolute encoder. The absolute position information is stored in the motor feedback. This memory has a battery powered backup for the electronic circuit. The battery is designed for a operating life of 10 years. If the battery voltage drops below 2.8 V, this message appears. The absolute encoder function is preserved for about 2 weeks.

連接的電機(jī)有一個(gè)絕對(duì)編碼器。絕對(duì)位置信息被存儲(chǔ)在電動(dòng)機(jī)反饋中。這個(gè)存儲(chǔ)器有電池電子電路的備用電源。該電池設(shè)計(jì)用于使用壽命為10年。如果蓄電池電壓降至2.8 V以下，則出現(xiàn)消息。絕對(duì)編碼器功能保留約2周。

Instructions for Exchanging Batteries更換電池的說(shuō)明

Have the following tools and accessories ready:

準(zhǔn)備好以下工具和附件：

• Torx screwdriver, size 10•Torx螺絲刀，尺寸10

• Needle nose pliers, torque wrench•尖嘴鉗、扭矩扳手

• New packaged battery (Part No.: 257101)•新包裝電池（零件號(hào)：257101）

上海仰光電子科技有限公司專(zhuān)業(yè)從事各品牌伺服驅(qū)動(dòng)器維修,伺服電機(jī)維修。If the control voltage of the installed battery is turned off, the absolute position is lost.如果已安裝電池的控制電壓關(guān)閉失去了位置。

The absolute position must be re-established through the process of the command Set Absolute Measurement.

必須通過(guò)命令“設(shè)置絕對(duì)測(cè)量"。
