专业维修博士力士乐伺服驱动器:故障解析:
E257故障含义:Continuous Current Limiting Active
持续电流限制激活
Description:故障说明:
The drive controller sets the peak current available for 400ms. Thereafter,
the continuous current limit becomes active and dynamically limits the
peak current to the continuous current.驱动控制器将峰值电流设置为400ms。之后
连续电流限制变为有效,并动态地限制峰值电流转换为连续电流。
Cause:原因:
More continuous torque was required than was available
需要比可用扭矩更大的持续扭矩
Remedy:解决措施:
1. Check the drive installation.检查驱动器安装。
2. 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)检查电机的安装情况。对于具有长时间使用,检查是否存在驾驶条件已发生变化(关于污染、摩擦、已移动等)
