Terminal Board not Connected

¿Qué significa CPF25 ?

This fault indicates that the terminal board is not properly connected to the drive. A loose or disconnected terminal board will disrupt essential I/O functionality and communication, preventing normal drive operation.

• Terminal board connector not fully seated in its receptacle on the drive main board.
• Physical damage to the terminal board connector pins or the drive's mating receptacle.
• Broken latching mechanism on the terminal board preventing secure connection.
• Accumulation of dust or debris in the connector socket preventing full electrical contact.
• Damage to the flexible PCB cable (if present) connecting the terminal board to the main board.
