Column name
Meaning
Block name
Describes the family of the object. If the object does not belong to a block, the object name is taken
as block name.
Object name
Defined name of the object.
Index
16 bit index that addresses the entry in the object dictionary. In case of a simple variable this refer-
ences the value of this variable directly. In case of records and arrays, the index addresses the
whole data structure. Then the 8 bit sub-index allows access to individual elements in the structure.
Sub-index
If the object is defined as a record or array, the sub-index defines an element in the structure.
Parameter name
Defined name of the parameter.
Data type
Data type of the parameter.
INTn
Integer with n bits
FLOAT32
Floating point with 32 bit
char
Character (ASC II)
STRING
String of characters
UINTn
Unsigned integer with n bits
DOMAIN
Application specific data block
Access
Access permission for the parameter.
rw
Read and write allowed
wo
Write only
ro
Read only
Persistence
Defines whether the parameter can be saved in non-volatile memory. If the persistence is set to "Y",
the saved value stays in memory even after the device is turned off. Parameters not marked as per-
sistent ("N") lose their settings after the device is turned off. The parameters with the access type
"read only" are marked with "-". This means that the parameter cannot be changed by the user.
Value range
Allowed value range for the object.
Default
Default values:
The default values in this document are firmware preset values. These values can be changed dur-
ing calibration or set up with model specific parameters during production of the servo valve.
Factory settings:
The factory settings are values which are set up model specific during production of the servo valve.
These parameters no longer contain the firmware default preset values.
Chapter "9 Storing / restoring parameters", page 295
Specification
Related (field bus) standard defining the parameter.
Possible entries:
CiA 301
Parameters correspond to CiA 301 (CANopen).
CiA 408
Parameters correspond to CiA 408.
Moog DCV
Moog defined parameters for digital control valves.
PDO mapping
If set to "Y", the parameter can be mapped into a PDO.
If set to "N", the parameter cannot be mapped into a PDO.
Short name
Unique short name.
Table 3: Field bus independent attributes
The listed default values contain the firmware preset values and not necessarily the configuration
of the delivered servo valve.
