RAM Anomaly (Remote Display)
Schneider Electric · Altivar 312 Variable Frequency Drive
Hva betyr rAM.E ?
This error indicates that the remote display terminal has detected an internal Random Access Memory (RAM) anomaly. This points to a critical internal hardware malfunction within the display terminal's temporary data storage. The terminal's ability to process and display information will be impaired.
Vanlige årsaker
- Internal Random Access Memory (RAM) data corruption within the remote display unit due to transient errors or hardware degradation.
- Manufacturing defect in the RAM chip of the display unit, causing unreliable data storage and retrieval.
- Transient power disturbances (sags, surges) affecting the display's control power supply (e.g., 24VDC), leading to memory corruption.
- Electromagnetic discharge (ESD) damage to the display's internal circuitry, impacting RAM functionality.
- Critical internal hardware malfunction within the display terminal's memory components preventing proper operation.

1. Power cycle the remote display unit by physically disconnecting it from the drive for at least 30 seconds and then reconnecting it.
- 2
2. Monitor the quality of the incoming control power supply to the drive and, consequently, the display (e.g., 24VDC) for any sags, surges, or transients.
- 3
3. Ensure proper static discharge (ESD) precautions are followed when handling or installing the remote display unit to prevent future damage.
- 4
4. If the display has configurable internal settings, perform a factory reset via the display menu (if accessible) to clear any potentially corrupted volatile memory.
