6.3.5 Saving Operating Data on a Memory Card
6.3.5.1 Information on Saving Data on a Memory Card
You can save all the data collected from the inverter to a memory card. The save-to-memory-card feature is disabled by
default. If a memory card is inserted into the slot of the communication unit and data storage on external storage
media is enabled, the communication unit will copy all data from the internal ring buffer to the external SD memory
card. The communication unit continues to store data on the memory card for as long as the memory card is inserted in
the slot. The communication unit creates a folder on the memory card. The name of the folder is "SC-
COM_[SerialNumber]". [SerialNumber] designates the serial number of the respective communication unit. In this
folder, the communication unit creates a new subfolder for each day. Each subfolder contains all the data collected by
the communication unit. When the memory card has reached its capacity, the LED H5 glows red and the
communication unit ceases to store data on the memory card. Replace the memory card or reformat it on the
computer.
Data loss if memory card is removed
Do not remove the memory card while the communication unit is in process of storing data. This can damage the
file system of the memory card and lead to data loss. Depending on the amount of data, the write process can
take some time.
