ABB ZMU-02 inverter memory card

The data encryption function cannot be enabled

Possible reasons: The firmware version of the memory card is too old and does not support the latest data encryption function; The encryption key is not configured correctly, causing the encryption function to fail to start properly.

Solution: Update the memory card firmware to the latest version in a timely manner to obtain complete data encryption support; Use the official tools provided by ABB to generate and correctly configure encryption keys to ensure the proper functioning of encryption functions.

Memory card lifespan expiration prompt

Possible reason: The write/erase frequency of the memory card has reached its design limit (usually about 3000 P/E cycles), and as the usage time increases and write operations become frequent, the memory card gradually ages.

Solution: Immediately backup important data in the memory card to prevent data loss; Timely replace the new memory card to ensure the normal operation of the device's data storage function. Some devices support the use of wear leveling algorithms to extend the lifespan of memory cards, which can be enabled in the device settings (if the device has this feature).
