Incompat MCB- PB

What does 106 mean?

The main control board (MCB) did not recognize the power structure (PB), indicating a firmware or hardware incompatibility, or a communication issue between the two boards. This prevents proper drive initialization and operation. The drive will not be able to function until the firmware revisions are harmonized.

• Firmware version mismatch between the main control board (MCB) and the power board (PB).
• Improper seating or connection of the main control board to the power board backplane connector.
• Damage to the backplane communication pins or connectors between the MCB and PB.
• Installation of an incompatible main control board model or series with the existing power board.
• Internal power board communication circuit failure or defective identification module.

1. 1

   1. Verify that the main control board (MCB) is correctly seated and fully engaged into its slot on the power board backplane.

2. 2

   2. Carefully inspect for any visible damage, bent pins, or debris on the backplane connector between the MCB and PB.

3. 3

   3. Compare the firmware versions of both the MCB and PB using programming software (e.g., DriveTools SP); update to compatible versions if necessary.

4. 4

   4. Confirm the compatibility of the installed MCB with the specific power board model number and revision using product documentation.

5. 5

   5. If physical connection and compatibility are confirmed, consider replacing the main control board (MCB); if the fault persists, replace the power board (PB).
