Respective diagnostic messages in the case of possible command errors:
• C2201 Parameter conversion error
• C2202 Error when writing data to non-volatile memory
After all application-specific parameter values are saved (C2200) it is also
possible to only save selected parameter values in the flash memory.
These parameters are overwritten with a current value. This is done by
• S-0-0293, C2400 Selectively backup working memory procedure
command.
The C2400 command can be used for internally saving a parameter
group the values of which have to be optimized again during operation, for
example. It is advisable to determine the IDNs of this parameter group by
clearing IDNs that are not required from the default list of
• S-0-0270, Selected IDN list of operation data to backup
Note:
In the case of "volatile storage", the C2200 command has to
be executed at least once before starting the C2400
command, because otherwise basic parameter values are
maintained for some parameter values in the flash memory.
Respective diagnostic command message:
• C2400 Selectively backup working memory procedure command
Respective diagnostic messages in the case of possible command errors:
• C2401 Parameter conversion error
• C2402 Error when saving parameters

Service Functions"
An appropriate master communication interface or the serial interface can
be used for loading and saving parameter values via the control master or
DriveTop.
Loading saved parameter values acc. to list parameter S-0-0192 to
reestablish the original status after initial commissioning is impossible in
the case of drives with absolute value encoder and modulo scaling (see
note).
Note:
In the case of drives with absolute value encoder and modulo
scaling, the backup of parameter values made after initial
commissioning acc. to S-0-0192 mustn't be loaded for
reestablishing the original parameter status! The actual
position value after the loading process would be
incorrect, but this cannot be detected on the controller
side!

If other interfaces than SERCOS interface are used for loading and
storing, communication phase "P2" has to be activated for loading
parameter sets:
