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
Explanation
Indicates the object size.
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.
Indicates whether the object can be mapped in cyclic communication.
Indicates the initial value of the object.
Indicates the object range. If a value outside the range is written, a parameter external error (error code CCD4h) occurs.
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.
STM
The unit can be changed to 10
STM can be changed with the "Feed length multiplication" (STM) setting of [Pr. PT03].
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".
Indicates where data is stored in the non-volatile memory.
