博世力士乐伺服驱动器维修测试台：
E251含义：Motor Overtemperature Warning
电机过热警告
Description:
As soon as the temperwature warning threshold (145°C) is exceeded, warnig E251 is generated and the drive complies with the command value.一旦超过温度警告阈值（145°C），就会生成警告E251，驱动器符合命令值。
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.这种状态可以无限持续，而不会发生断电。直到超过温度错误阈值，才会立即断电。

Cause:原因：
The motor became overloaded. The effective torque required of the motor
was above the allowable standstill continuous torque for too long.电机过载。电机所需的有效扭矩长时间高于允许的静止持续扭矩。
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)
检查电机的安装。对于已使用的系统长时间以来，检查驱动条件是否发生了变化（在
