Option Board Interconnection Fault

What does CPF23 mean?

An option board was not correctly connected to the control board, or an incompatible option board was attached. This fault indicates a problem with the physical interface or compatibility between the option and control boards, preventing data exchange.

• Option board is not properly seated in its slot on the main control board, leading to intermittent or no contact.
• Physical damage to the connector pins on the option board or the corresponding slot on the control board.
• An incompatible option board model installed, which the Drive's control board cannot recognize or interface with.
• Excessive vibration or shock causing the option board to become dislodged from its connection during operation.
• Debris (e.g., dust, metal shavings) obstructing the electrical contacts between the board and the slot.

Click steps to track your progress.

1. 1

   Power off the Drive and physically remove the option board, then re-insert it firmly, ensuring all connectors are fully engaged.

2. 2

   Visually inspect the pins on the option board and the socket on the control board for any signs of bending, corrosion, or foreign material.

3. 3

   Refer to the Drive's hardware manual to confirm the installed option board's part number is compatible with the Drive model and series.

4. 4

   Verify that any retaining clips or screws designed for the option board are secured to prevent movement during operation.

5. 5

   Check the ambient conditions for excessive vibration near the Drive mounting location that could dislodge internal components.
