Keypad Loss (Cannot Write to LCD, Adv. Code 2)

What does 24 mean?

This fault indicates an issue with the keypad or its connection where the drive is unable to write data to the keypad's LCD display. This prevents the display of status, parameters, or fault information to the user, effectively rendering the local interface unusable for monitoring or configuration.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Try reseating the keypad connection multiple times, or gently cleaning the contacts.

2. 4

   If possible, try testing with a known good keypad to isolate whether the issue is with the keypad unit itself or the drive's communication interface.
