1011h Restore Default Parameters
Object description
With this object the default values of parameters according to the communication and device profile are
restored. By read access the device provides information about its capabilities to restore these values.
Entry description
Sub-Index 00h
Name number of entries
Access ro
PDO Mapping No
Data Type UNSIGNED 8
Default Value 01h
Sub-Index 01h
Name restore all default parameters
Access rw

Data Type UNSIGNED 32
Default Value 01h
In order to avoid the restoring of default parameters by mistake, restoring is only executed when the signature
"load" is written to sub-index 1.

On reception of the correct signature in sub-index 1 the device restores the default parameters and then
confirms the SDO transmission (initiate download response). If the restoring failed, the device responds with
an Abort SDO Transfer (abort code: 0606 0000h). If a wrong signature is written, the device refuses to restore
the defaults and responds with an Abort SDO Transfer (abort code: 0800 002xh).
The default values are set valid after the device is reset (reset node or power cycled)
On read access to sub-index 1 the device provides information about its default parameter restoring capability
with the following format:
