PwrBd Invalid ID

Was bedeutet 111 ?

The power structure ID is invalid, meaning the main control board cannot correctly identify the connected power structure. This suggests a communication issue or a fundamental mismatch between the boards. The drive cannot start or operate safely without proper identification of its power components, leading to a shutdown.

• The main control board (MCB) cannot read or incorrectly reads the power board's unique identification code.
• Physical damage to the power board's ID chip or related circuitry on the power board.
• Corrupted power board ID data stored in its non-volatile memory due to power disturbance.
• Intermittent or poor connection between the main control board and the power board backplane.
• Installation of a power board from a different product family or incompatible series.

1. 1

   1. Perform a drive power cycle by disconnecting input power (e.g., 480VAC) for 30 seconds.

2. 2

   2. Ensure the main control board (MCB) is fully and correctly seated into its slot on the power board backplane.

3. 3

   3. Visually inspect the backplane connector between the MCB and PB for bent, damaged, or corroded pins.

4. 4

   4. Verify the power board part number and series against compatibility charts for the installed MCB using product documentation.

5. 5

   5. If the issue persists after these checks, replace the power board as its identification circuit or data may be faulty.
