10 OBJECT DICTIONARY
10.1 Object dictionary list

OBJECT DICTIONARY
Each data such as control parameters, command values, and feedback values is handled as an object composed of an
address, object name, data type, access rule, and other elements. The object data can be exchanged between the master
station (controller) and the slave stations (servo amplifiers). The aggregate of these objects is called object dictionary.
10.1
Object dictionary list
The object dictionary list structure is as follows.
Item
Explanation
Data Type
Indicates the object size.
Access
Indicates whether the object can be read or written.
ro: Only reading is available.
wo: Only writing is available.
rw: Reading and writing are available.
Variable mapping
Indicates whether the object can be mapped in cyclic communication.
Default
Indicates the initial value of the object.
Range
Indicates the object range. If a value outside the range is written, a parameter external error (error code CCD4h) occurs.
Units
Indicates the object unit.
-: No unit
r/min, mm/s: In the linear servo motor control mode, the unit is mm/s. In other control modes, the unit is r/min.
pos units: This is the positioning command unit.
The unit can be changed to 10
STM

(STM-4)
[inch], 10
-3
[degree], or [pulse] with the setting of [Pr. PT01].
STM can be changed with the "Feed length multiplication" (STM) setting of [Pr. PT03].
EEP-ROM
Indicates whether data can be stored in the non-volatile memory.
: Data cannot be stored in the non-volatile memory. The value of the data written from the controller returns to the
value of "Default" when the power is shut off.
: Data can be stored in the non-volatile memory with [Store Parameters (1010h)].
Data is saved in the servo parameter corresponding to the object. For the corresponding servo parameters, refer to
"Parameter".
Parameter
Indicates where data is stored in the non-volatile memory.
