Diagnostic message power supply erroneous

What does E353 mean?

The Indramat HVE or HVR power supply unit cyclically sends status and error messages via a serial connection to the connected controller (DIAX04 SSE-03VRS). This warning is generated if the controller does not receive several sequential messages, indicating a communication breakdown.

• The serial interface of the power supply unit (HVE/HVR) is defective.
• A break or damage in the serial connection lines (bus cable) between the power supply unit and the controller.
• The serial interface of the controller (DIAX04 SSE-03VRS) is defective.

Click steps to track your progress.

1. 1

   Visually inspect the serial bus cable connecting the HVE/HVR power supply unit to the DIAX04 SSE-03VRS controller for any signs of damage or loose connections.

2. 2

   Check the termination and continuity of the bus cable, and replace it if necessary.

3. 3

   If the bus cable and connections are verified, consider replacing the HVE/HVR power supply unit if its serial interface is suspected to be defective.

4. 4

   If the fault persists after checking the cable and power supply, the serial interface of the DIAX04 SSE-03VRS controller may be defective, requiring controller replacement.
