1. The signal line of the driving device is suspended without fixing or shielding grounding.
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. Generally, the cable from large driving device to motor shall not pass through the terminal transition, but shall be led out directly.
4. Shielded cables shall be used for motor cables, and the shielding layer shall be hooped.
5. The system incoming line layout design is unreasonable, blocking the cooling air duct of the driving device.
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 bus is not fixed and shielded correctly, and accessories for fixing and shielding cable of cu320 module are missing.
2. The encoder line and device communication line are suspended at will, not fixed, and the encoder line is not shielded.
3. Cu320 control unit and interface module are not grounded.
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. The design of cabinet incoming line position is unreasonable.
