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

PDO Mapping No

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:
