Items Description
Memory Capacity XMC supports up to 32 GB Micro SD memory card. Supports SPI Mode, SD and SDHC.
File System FAT32
Voltage Range 2.7 ~ 3.6V
Static Tolerance Should satisfy IEC 61000-4-2
Number of Detachments Up to 10,000 times
Current Consumption Up to 100 mA when reading or writing
Number of Read/Writes Up to 100,000 times
Size 15 mm x 11 mm x 1 mm

XMC supports up to 32 GB Micro SD memory card but there is a limit on the storage amount used.

  • Only 6.4 GB of the memory card is used. This is to prevent excessive processing time when accessing large amounts of SD memory.

  • The SD memory state may affect main task time when performing reads or writes.

  • The Micro SD memory card needs to be formatted to FAT32 before being used in the XMC controller.

  • When using SD memory for a long time, formatting on a regular basis is required to maintain peak performance.

  • Verify that SD memory card writing is completed before powering off or resetting the motion controller. If the motion controller is power cycled during a memory card write, damage may occur to the SD memory card file system and any data in the write buffer will be lost and not written to the SD memory card.

  • A small amount of time is required for suspension of the datalogging. The time required to stop datalogging when receiving a stop command will depend on the amount of data collected.

  • Do not forcibly remove the SD memory card during a read or a write. This will damage the file system of the memory card. Only remove the SD memory card after disabling the datalog functionality by pressing the SD CMD button on the front for more than 3 seconds.

  • Close the cover on the XMC to prevent the SD memory card from being removed due to machine vibration.
