5 SDO service
5.1
General
The device supports 1 SDO server (Expedited read/write, segmented read)
5.2
Save/load parameters
The device supports saving parameters to a non-volatile memory.
5.2.1
Save
Writing “save” to 0x1010-x saves the corresponding objects to the non-volatile memory. After a reset or power-on, the
parameters are loaded from the non-volatile memory. The SDO request to 1010h-x is answered after saving.
5.2.2
Load
Writing “load” to 1011h-x restores the corresponding objects. The parameters are restored after a reset or power-on.
5.2.3
Safe non-volatile operation
To ensure safe non-volatile operation, the time between access object 1010h-x or 1011h-x and a reset or power-on has
to be at least 600 ms.
5.2.4
Side effect
Save/Load operations interrupt the updating of position.
