A general fault has been detected within the drive's control circuitry. This indicates an internal malfunction of the control logic, affecting overall drive operation. (Similar to CPF14).
Click steps to track your progress.
Verify input voltage (L1, L2, L3) and frequency at the drive's input terminals against nominal specifications and check for phase imbalance.
Inspect all control wiring connections (e.g., digital I/O, analog I/O, communication cables) for loose terminals, damage, or improper shielding.
Inspect drive cooling fans for proper operation and ensure heatsinks and ventilation openings are free from dust and obstructions.
Review relevant drive parameters related to control modes, I/O configuration, and safety functions to ensure correct setup and integrity against a known good configuration.
