PU: load error ID tag

Hva betyr 0x63A2 ?

This fault indicates that the calibration data of the power unit (PU) is either incompatible or faulty. This leads to immediate inverter disablement and motor coasting, and requires a mains power cycle to reset.

• Incompatible power unit (PU) installed in the inverter, not matching the control unit's expected ID tag or rating.
• Corruption of the power unit's internal memory where calibration data (ID tag) is stored.
• Physical damage or electronic failure of the power unit hardware (e.g., internal communication board).
• Firmware mismatch between the control unit (CU) and the power unit (PU), preventing proper communication and identification.
• Poor electrical connection between the control unit and the power unit.

1. 1

   Perform a complete mains power cycle of the inverter (disconnect and reconnect the main supply) as specifically indicated by the fault description.

2. 2

   Verify that the power unit (PU) and control unit (CU) are correctly matched in terms of model, rating, and compatibility according to the manufacturer's documentation.

3. 3

   Visually inspect all connections between the control unit and power unit for proper seating, physical damage, or corrosion.

4. 4

   If possible, attempt to re-establish communication or re-initialize the power unit's ID tag through a specific diagnostic function in the inverter's menu.

5. 5

   If the fault persists after these steps, replacement of the power unit (PU) with a compatible and correctly sized spare is likely required.
