1010h Store Parameters
Object description
This object supports the saving of parameters in non volatile memory. By read access the device provides
information about its saving capabilities.
Entry description

In order to avoid storage of parameters by mistake, storage is only executed when the signature "save" is
written to Subindex 1.

On reception of the correct signature in sub-index 1 the device stores the parameter and then confirms the
SDO transmission (initiate download response). If the storing failed, the device responds with an Abort SDO
Transfer (abort code: 0606 0000h). If a wrong signature is written, the device refuses to store and responds
with Abort SDO Transfer (abort code: 0800 002xh).
On read access to Sub-Index 1 the device provides information about its storage functionality with the
following format:
