• When System.Cd.Storage_sdcRemovalProhibit is TRUE, removal using the SD memory card access control switch is
ignored. To remove an SD memory card while System.Cd.Storage_sdcRemovalProhibit is TRUE, set
System.Cd.Storage_sdcForcedDisable to TRUE. Then, System.Cd.Storage_sdcRemovalProhibit turns FALSE in the
system and the SD memory card can be removed.
• Removal of an SD memory card is registered with the event history (type: operation).
• Do not remove an SD memory card while the CARD READY LED is not turned OFF. Doing so may damage
the data on the SD memory card.
• Even while the SD memory card is accessed (CARD ACCESS LED is ON), holding the SD memory card
access control switch for longer than 1s operates the SD memory card forced disable function, and the SD
memory card can be stopped access (removal enabled).
■Release of the SD memory card forced disable state
The SD memory card forced disable state can be released by turning System.Cd.Storage_sdcForcedDisable from TRUE to
FALSE. Also, either of the following operation automatically sets System.Cd.Storage_sdcForcedDisable to FALSE and the SD
memory card is enabled.
Operation
Install the SD memory card again. (The CARD READY LED turns from flashing to ON.)
Turn ON the power of the Motion module again or carry out reset operation.
