cF2 Read/Write Error fault in delta drive

cF2 Read/Write Error fault in delta drive troubleshooting

Description

Similar to cF1, cF2 indicates a failure to write data to the internal memory. This often happens during startup checks.

Causes

1. Control Board Aging: Component degradation over time.
2. Loose Keypad: On some models, poor connection between the keypad and the drive can cause communication data errors mistaken for memory errors.
3. Power Instability: Unstable control voltage (low 24V or 5V rail).

Solution

Hardware check:
1. Power Cycle: Turn off the drive completely, wait for the display to go dark, and power on again.
2. Check Connections: Reseat the keypad and any ribbon cables connecting the control board to the power board.
3. Repair: If persistent, this requires professional board-level repair or drive replacement.
