力士乐整控制器修理TDA系列伺服驱动器F248蓄电池故障修理

F248： Low Battery Voltage蓄电池电压低。力士乐伺服驱动器警报原因多种多样，在我们维修的众多案例中原因有的集中有点分散，原因各不统一。

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.

连接的电机有一个绝对编码器。绝对位置信息被存储在电动机反馈中。这个存储器有电池电子电路的备用电源。该电池设计用于使用寿命为10年。如果蓄电池电压降至2.8 V以下，则出现消息。绝对编码器功能保留约2周。

Instructions for Exchanging Batteries更换电池的说明

Have the following tools and accessories ready:

准备好以下工具和附件：

• Torx screwdriver, size 10•Torx螺丝刀，尺寸10

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

• New packaged battery (Part No.: 257101)•新包装电池（零件号：257101）
