9 Storing / restoring parameters
The electronics of the servo valve provide a non-volatile memory which allows storing parameters. The cur-
rent values of all parameters declared as non-volatile (persistence = "Y") can be stored in a non-volatile mem-
ory on the servo valve. Three storing / restoring operations are possible:
• Parameters can be stored in the non-volatile memory.
Chapter "9.1 Storing parameters", page 296
• Parameters are automatically restored while power on.
The stored parameters are automatically reloaded during a power on cycle.
• Factory settings can be restored
Chapter "9.2 Restoring parameters to factory settings", page 297
The following table describes the behavior of the savable and volatile parameters when performing a store pa-
rameters, servo valve bootup or restore parameters operation.
Parameters are stored and restored in accordance with the procedure described in the common
device profile CiA 301.
Operation
Non-volatile parameters (persistence = "Y")
Volatile parameters (persistence = "N")
Default value defined
for the parameter
Default value = "None"
Bootup servo valve
Parameter values will be loaded.
Factory default values will
be loaded.
No values will be loaded.
Store parameters
Parameter values will be saved.
No values will be saved.
No values will be saved.
Restoring factory settings
Factory values of the parameters will be loaded.
Factory default values will
be loaded.
No values will be loaded.

The write access to any parameter will not affect its default value.
