1011h – Restore default parameters
This object controls the restore of parameters in non-volatile memory to their default values, according to the commu-
nication and device profile.
In order to avoid restoring of parameters by mistake, restoring is only executed when the signature “load” is written to
the sub-index 1, so that all parameters are restored in non-volatile memory.
The restore default parameters write access structure is specified in the following figure.

By read access the sub-index 1 of this object, the device provides information about its restoring capabilities. Giving
the value of 1, it means that the device can restore parameters on command.
The default values are set valid after the device is power cycled.

For the GEFRAN RK5C CANopen device, the Restore default parameters command does not apply to these objects:
-
COB-ID SYNC (1005h)
-
COB-ID EMCY (1014h)
-
COB-ID of TPDO1 (1800h, sub-index 1)
-
COB-IDs of 1st SDO (1200h, sub-index 1 and 2)
The value of the above listed objects is modified only after a change of the Node-ID value.
