Clock Fault

What does CPF16 mean?

An error has occurred with the internal clock circuit of the drive, which is essential for timing and synchronization of operations. This can cause timing inaccuracies and operational issues.

Click steps to track your progress.

1. 1

   Verify stable input AC supply voltage at L1/R, L2/S, L3/T terminals against drive specifications.

2. 2

   Verify DC bus voltage stability via the drive's display or accessible test points, ensuring no significant fluctuations.

3. 3

   Inspect drive grounding connections and motor cable shielding for proper termination and integrity, ensuring minimal EMI interference.

4. 4

   Backup current drive parameters and then perform a parameter initialization to factory defaults to rule out corrupted settings.
