力士樂伺服驅(qū)動器維修公司：上海仰光電子在力士樂REXROTH伺服維修方面已經(jīng)形成一套完善的維修技術(shù)流程，擁有大部分力士樂型號維修軟硬件測試系統(tǒng)，兼維修技術(shù)經(jīng)驗，經(jīng)過數(shù)10多年的維修技術(shù)積累，博士力士樂維修修復(fù)率可達96%左右,現(xiàn)在我們主要談?wù)勛罱槍ακ繕夫?qū)動器hcs系列報E251故障維修成功案例：
博世力士樂伺服驅(qū)動器維修測試臺：
E251含義：Motor Overtemperature Warning
電機過熱警告
Description:
As soon as the temperwature warning threshold (145°C) is exceeded, warnig E251 is generated and the drive complies with the command value.一旦超過溫度警告閾值（145°C），就會生成警告E251，驅(qū)動器符合命令值。
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)可以無限持續(xù)，而不會發(fā)生斷電。直到超過溫度錯誤閾值，才會立即斷電。

Cause:原因：
The motor became overloaded. The effective torque required of the motor
was above the allowable standstill continuous torque for too long.電機過載。電機所需的有效扭矩長時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)
檢查電機的安裝。對于已使用的系統(tǒng)長時間以來，檢查驅(qū)動條件是否發(fā)生了變化（在
污染、摩擦、移動的部件等）
