1. The signal line of the driving device is suspended without fixing or shielding grounding.

2、 驱动装置布置安装不合理，应与进线滤波器电抗器一起单独组柜，不宜采用面板式安装，而应采用框架方式安装。

2. The layout and installation of the driving device is unreasonable, so it should be combined with the incoming filter reactor separately. The panel installation should not be adopted, but the frame installation should be adopted.

3、大型驱动装置至电机电缆一般不应该再经过端子过渡，而应直接出线。

3. Generally, the cable from large driving device to motor shall not pass through the terminal transition, but shall be led out directly.

4、电机电缆应使用屏蔽电缆，屏蔽层应抱箍。

4. Shielded cables shall be used for motor cables, and the shielding layer shall be hooped.

5、系统进线布置设计不合理，阻挡驱动装置冷却风道。

5. The system incoming line layout design is unreasonable, blocking the cooling air duct of the driving device.

6、主进线不宜使用端子，应采取铜排结构件压接电缆方式。

6. The terminal should not be used for the main incoming line, and the copper bar structure should be used to crimp the cable.

Analysis and comparison of common problems of complete electrical equipment. Have you been recruited?

1、DP总线未正确的固定与屏蔽，CU320模块的用于固定与屏蔽电缆线的附件缺失。

1. DP bus is not fixed and shielded correctly, and accessories for fixing and shielding cable of cu320 module are missing.

2、编码器线，装置通讯线随意悬空，未作固定，编码器线亦未作屏蔽。

2. The encoder line and device communication line are suspended at will, not fixed, and the encoder line is not shielded.

3、CU320控制单元及接口模块均未做接地处理。

3. Cu320 control unit and interface module are not grounded.

4、传动装置未安装屏蔽附件，安装位置偏低，且被线槽阻挡，导致冷却风道被阻挡，装置进出线不合理。

4. The transmission device is not equipped with shielding accessories, the installation position is low and blocked by the trunking, resulting in the blocking of the cooling air duct and the unreasonable inlet and outlet lines of the device.

5、柜体进线位置设计不合理。

5. The design of cabinet incoming line position is unreasonable.
