3.2.8 Object 1011h: Restore Parameters
This object supports the restoring of the default values for the object dictionary in non-
volatile memory. In order to avoid restoring of parameters by mistake, the device restores
the defaults only when a specific signature is written to the appropriate sub-index. The
signature is “load”. The “load” action on either CAN buses will apply to the parameters on
both buses.
The signature is a 32-bit unsigned number, composed of the ASCII codes of the signature
characters, according to the following table:
MSB
LSB
d
a
o
l
64h
61h
6Fh
6Ch
On reception of the correct signature to an appropriate sub-index, the controller will
restore the defaults in non-volatile memory, and then confirm the SDO transmission.
The
default values are set valid only after the device is reset or power-cycled.
This
means that the controller will NOT start using the default values right away, but rather
continue to run from whatever values were in the Object Dictionary prior to the restore
operation.
