cF1 Internal EEPROM Error fault in delta drive

cF1 Internal EEPROM Error fault in delta drive troubleshooting

Description

cF1 indicates a corruption in the internal memory (EEPROM) where parameters are stored. The drive cannot reliably read the saved settings.

Causes

1. Power Failure during Write: Power was cut exactly while the user was saving a parameter or while the drive was performing a reset.
2. Electrical Noise: Severe electromagnetic interference corrupted the data transfer.
3. Hardware Failure: The memory chip on the control board has physically failed.

Solution

Attempt a reset:
1. Factory Reset: Perform a parameter reset to factory defaults (usually Parameter 00-02 set to 9 or 10). This clears the corrupted memory and rewrites default values.
2. Reprogram: Re-enter the necessary motor and application parameters after the reset.
3. Replace Board: If the fault returns immediately after power cycling or resetting, the control board is defective and must be replaced.
