力士樂(lè)伺服驅(qū)動(dòng)器維修公司：上海仰光電子在力士樂(lè)REXROTH伺服維修方面已經(jīng)形成一套完善的維修技術(shù)流程，擁有大部分力士樂(lè)型號(hào)維修軟硬件測(cè)試系統(tǒng)，兼維修技術(shù)經(jīng)驗(yàn)，經(jīng)過(guò)數(shù)10多年的維修技術(shù)積累，博士力士樂(lè)維修修復(fù)率可達(dá)96%左右,現(xiàn)在我們主要談?wù)勛罱槍?duì)力士樂(lè)驅(qū)動(dòng)器hcs系列報(bào)E251故障維修成功案例：
博世力士樂(lè)伺服驅(qū)動(dòng)器維修測(cè)試臺(tái)：
E251含義：Motor Overtemperature Warning
電機(jī)過(guò)熱警告
Description:
As soon as the temperwature warning threshold (145°C) is exceeded, warnig E251 is generated and the drive complies with the command value.一旦超過(guò)溫度警告閾值（145°C），就會(huì)生成警告E251，驅(qū)動(dòng)器符合命令值。
This state can last infinitely without a powering down occurring. Not until the temperature error threshold is exceeded will an immediate powering down take place.這種狀態(tài)可以無(wú)限持續(xù)，而不會(huì)發(fā)生斷電。直到超過(guò)溫度錯(cuò)誤閾值，才會(huì)立即斷電。

另請(qǐng)參閱F219電機(jī)過(guò)熱停機(jī)
Cause:原因：
The motor became overloaded. The effective torque required of the motor
was above the allowable standstill continuous torque for too long.電機(jī)過(guò)載。電機(jī)所需的有效扭矩長(zhǎng)時(shí)間高于允許的靜止持續(xù)扭矩。
Remedy:
Check the installation of the motor. For systems which have been in use
for a long time, check to see if the drive conditions have changed (in
regards to pollution, friction, components which have been moved, etc)
檢查電機(jī)的安裝。對(duì)于已使用的系統(tǒng)長(zhǎng)時(shí)間以來(lái)，檢查驅(qū)動(dòng)條件是否發(fā)生了變化（在
污染、摩擦、移動(dòng)的部件等）
