rexroth博世力士樂(lè)伺服驅(qū)動(dòng)器過(guò)熱警告維修：
E251含義：Motor Overtemperature Warning
電機(jī)過(guò)熱警告
Description:故障說(shuō)明：
As soon as the temperwature warning threshold (145°C) is exceeded,
一旦超過(guò)溫度警告閾值（145°C）
warnig E251 is generated and the drive complies with the command value.，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。

湖州力士樂(lè)驅(qū)動(dòng)器修理：：
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:補(bǔ)救措施：
Check the installation of the motor.
檢查電機(jī)的安裝。
For systems which have been in use for a long time, check to see if the drive conditions have changed (inregards to pollution, friction, components which have been moved, etc)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）
